Creating a Windows XP password reset disk is a great way to protect yourself from the possibility of forgetting your account password. With it, you can easily reset your password and get right in to Windows XP. While there are ways to recover lost passwords without a password reset disk, they are often complicated and time consuming.
Be proactive by creating a password reset disk today. With a password reset disk, forgetting your password is no longer a crisis.
Follow the easy steps below to create a password reset disk for your Windows XP account:
Difficulty: Easy
Time Required: Creating a password reset disk for your Windows XP logon usually takes less than five minutes
Here's How:
1.
Click on Start and then Control Panel.
2.
Click on the User Accounts link.
Note: If you're viewing the Classic View of Control Panel, double-click on the User Accounts icon.
3.
In the pick an account to change area of the User Accounts window, click on your Windows XP user name.
4.
In the Related Tasks area on the left, click the Prevent a forgotten password link.
5.
When the Forgotten Password Wizard window appears, click Next
Note: You will need a floppy disk drive and a blank floppy disk.
6.
On the next screen, verify that a blank floppy disk is inserted in your floppy disk drive.
Click Next to continue.
7.
With the disk still in the drive, enter your current account password in the text box and click Next.
8.
Windows XP will now create the password reset disk.
When the progress indicator shows 100% complete, click Next and then click Finish in the next window.
9.
You can now remove the floppy disk from your computer.
Label the disk "Password Reset" and store it in a safe place.
Tips:
1.
Not a Windows XP user? Creating a password reset disk in Windows Vista is very similar to creating a password reset disk in Windows XP.
2.
You only need to create a password reset disk for your Windows XP logon password once. No matter how many times you change your password, this disk will always allow you to create a new one.
3.
While a password reset disk will certainly come in handy if you ever forget your password, keep in mind that anyone who possesses this disk will be able to access your account at any time, even if you change your password.

Before You PC Power Supplies
Power supply units (PSUs) are often overlooked when building a computer system. A poor quality PSU can greatly reduce the life span of a good system or cause instability. A high quality PSU can also help reduce the noise or heat generated within a computer system. Whether you are buying one for a new computer or replacing a old unit, here are some tips for purchasing a PSU.
Avoid Power Supplies Under $30
Most power supplies that are priced below $30 generally do not meet the power requirements of the latest processors. To make matters worse, the components used in them are of inferior quality and more likely to fail over time. While they may power the computer system, inconsistencies in the power to the components will tend to cause instability and damage to the computer.
ATX12V Compliant
Developments in processors, the PCI Express bus and graphics cards have all increased the amount of power required to operate them. To help provide this extra power, the new ATX12V standard was developed. The problem is that there are still a large number of older ATX power supplies available. Even if you are replacing an older power supply, ATX12V units are backwards compatible.
* ATX12V vs. ATX Power Supplies
Knowing the Wattage Ratings
Wattage ratings on power supplies can be deceptive as this is the total combined wattage of all the voltage lines. With the increased demands by components, the total required output particularly for the +12V line has become increasingly important. Ideally a power supply should have at least 18A on the +12V line. The actual load you need will vary depending upon your components.
* PC Power Supply Wattage
Low or No Noise
Power supplies generate a lot of noise from fans used to keep them from overheating. If you don't want a lot of noise, there are a number of options available. The best choice is for a unit that either uses larger fans that move more air through the unit at slower speeds or to get one with temperature controlled fans. Another option is fanless or silent power supplies that generate no noise.
* Silent PC Power Supplies
MTBF: Mean Time Between Failures
MTBF is the rating given by a manufacturer for the typical amount of usage a unit will have before a possible failure. Roughly 50% of units fail before this and 50% live longer. The higher the MTBF rating, the better the quality of the power supply. Avoid units with ratings of below 20,000 hours as this only equates out to roughly 2.25 years of continuous usage.
Power Efficiency
Power supplies convert voltages from wall outlets to lower levels used by the PC. During this conversion, some power is lost as heat. The efficiency level of the PC determines how much extra power must be put into the power supply to run the PC. By getting a more efficient power supply, you end up saving money through the use of less overall electrcity. Look for a unit that has the 80Plus logo showing that it has passed certification.

Having the Right Type And Number of Connectors
There are a variety of different power connectors that come off a power supply. Some of the different connectors include 20/24-pin power, 4-pin ATX12V, 4-pin Molex, floppy, 6-pin PCI-Express graphics and 8-pin PCI-Express graphics. Take stock of what power connectors your PC components require to ensure you get a power supply with the appropriate connectors.

PC Power Supply Efficiency
How The Efficiency Rating of A Power Supply Can Save You Money
Introduction
Personal computers use a tremendous amount of power these days. As the processors and components get more powerful, so does the amount of energy they need to consume. Some desktop systems now can consume almost as much power as a microwave oven. The problem is that even though your PC may have a 500W power supply, the amount of power that it actually pulls from the wall could be much higher than this. This articles takes a look at how much energy a power supply uses and what consumers can do when making a purchase to try and reduce that consumption.
Power In Versus Power Out
The electrical power that is supplied to your house runs at fairly high voltages. When you plug your computer system into the wall for power, this voltage does not flow directly to the components within the computer. The electrical circuits and chips run at much lower voltages than the current coming from the wall outlet. This is where the power supply comes in. It converts the 110/220V incoming power down to the 3.3, 5 and 12V levels for the various internal circuits.
Changing the voltages from one level to another requires various circuits that will lose energy as it gets converted. This means that the amount of power in watts used by the power supply will be greater than the amount of watts of energy that is supplied to the internal components. This energy loss is generally transferred as heat to the power supply and is why most power supplies contain various fans to cool the components.
The big thing to remember is that if you computer uses 300W of power on the inside, it is using more power from the wall outlet. The question is, how much more?
High Efficiency Power Supplies
The efficiency rating of a power supply determines how much energy is wasted or lost when it converts the wall outlet power to the internal power components. For example, a 75% efficiency power supply that generates 300W of internal power would draw roughly 400W of power from the wall. The important thing to note about a power supply is that the efficiency rate will vary depending upon the load amount on the circuits as well as the condition of the of the circuits.
Many power supply manufacturers are beginning to label units as high efficiency or HE. This is really a marketing term that can vary between manufacturers and even models. One high efficiency model might reach 80% efficiency levels while another might reach 85% efficiency. In addition, that 85% efficiency unit may only reach that percentage when it is at a 50% power load. When the unit is at 25 or 75% power loads, it may only have a 70% or lower level of efficiency.
Some manufacturers are now listing the power supply efficiency ratings. It should be noted that many of these still list the optimal efficiency level. Only a few will list the efficiency levels for various load levels on the power supply. Be sure to look for these numbers before buying any PC power supplies.
ENERGY STAR And Power Supplies
The Enery Star program was originally established by the EPA as a voluntary labeling program designed to indicate energy efficient products. It was initially established for computer products to help corporations and individuals mitigate energy expenditures. A lot has changed in the computer market since the program was initially established back in 1992.
Early ENERGY STAR products did not have to meet very strict energy efficiency levels because they didn't use as much power as they do now. Because of these increasing levels of power consumption, the ENERGY STAR program has been modified multiple times. The latest revision takes effect in July of 2007 and makes a very specific standard for the ENERGY STAR label for computer power supplies.
In order for new power supplies and PCs to meet the ENERGY STAR requirements, they must meet an 80% efficiency rating across all rated power output. This means that if the computer is running at 1%, 100% or any level in between, the power supply must reach a minimum 80% efficiency rating in order to get the label. This means that many high efficiency labeled power supplies will not meet this requirement. After all, if it only has 75% at a one quarter load, it fails to meet the guidelines.
These new ENERGY STAR guidelines should help users in finding a power supply that will help meet the needs of their computer systems yet still provide cost savings thanks to the efficiencies. Eventually, the ENERGY STAR group will look to increase the requirements from the 80% efficiency to a higher 85% at some future date.
When looking for a power supply, look for one that carries the 80 PLUS logo on it. This means that the power supply efficiency has been tested and approved to meet the ENERGY STAR GUIDELINES. The 80 PLUS Program provides a list of power supplies that have meet the requirements. This list is updated periodically and provides downloads of PDF's with their test results to let you see exactly how efficient they were.
Conclusions
The amount of power that we consume has become a major issue. Personal computers are becoming a standard item in the home similar to TVs and stereos. Because of this, it is important to try and select equipment that is as energy efficient as possible. By knowing what it really means for a power supply to be efficient, consumers can help reduce their power consumption and make some difference with the environment at the same time.

Saitek Cyborg Rumble Pad Review
The Bottom Line
If you are a PC gamer that prefers to play games with a gamepad rather than a mouse and keyboard, the Saitek Cyborg Rumble Pad is a very good gamepad. No matter if you prefer the Xbox 360 style control layout or the PS3 controller design; the Saitek Cyborg Rumble Pad can do what you want and has robust programming options. Overall the Saitek Cyborg Rumble Pad performs very well.
Pros
* Changeable layout
* Programmable buttons
Cons
* USB cable is too short
Description
* Robust, but somewhat overwhelming software allows lots of programming options.
* The Cyborg-module is hot swappable during a game if you decide to use a different layout.
* No drivers are needed to use the Cyborg Rumble Pad.
Guide Review - Saitek Cyborg Rumble Pad Review
The most unique feature of the Saitek Cyborg Rumble Pad is the Cyborg-module that houses the D-pad and left analog stick. An eject button on the bottom of the controller releases the Cyborg-module and allows you to arrange the left analog stick in two positions, a PS3 style layout puts the left and right analog sticks next to each other and the Xbox layout puts the left analog stick up higher on the control and places the D-Pad next to the right analog stick. You can change the module around during a game as well.
Another nice feature of the Saitek Cyborg Rumble Pad is the FPS buttons that when pressed lowers the sensitivity of the game pad to a setting of your choosing to make activities like sniping in game easier to pull off. The buttons on the controller have a nice tactile feel and the entire gamepad feels well built.
The only real problem I had with the Saitek Cyborg Rumble Pad during testing was that my desk is large and my PC far from my display which made the USB cable too short. The cable is about six feet long, but if you work from a large desk like I do you may find that isn’t enough cord. The Saitek SST software allows you to bind any mouse or keyboard stroke to the controller for complete customization. It is also nice that you don’t need to use the software or any drivers; you can simply plug the Saitek Cyborg Rumble Pad in and play.

Kodak EasyShare 5300 All-in-One Printer Review
Features & Specifications
Kodak’s middle of the road printer is what we are having a look at today. The Kodak EasyShare 5300 All-in-One Printer copies, scans, and prints just as you would expect an all-in-one to do. The biggest feature of the 5300 is the ink prices. Kodak moved the print head from the cartridge into the printer which allowed them to make inks much less expensive. You can get the black ink cartridge for $9.99 and the color ink cartridge costs $14.99. A kit with both cartridges is $22.99. The Epson RX700 I bought a year or so back takes six separate ink cartridges with each color cartridge costing $12.99 and the black cartridge costs $17.09. It cost me $64.95 for the color cartridges alone, when I could find them.
The print quality of the Kodak EasyShare 5300 All-in-One Printer is every bit as good as any photo printer I have used. Photographs have vivid colors, prints are smudge-proof and skin tones are realistic. You can’t tell the difference between prints form the Kodak EasyShare 5300 All-in-One Printer and ones I developed professionally. The printer can put out black document pages at 32 ppm and Kodak quotes print time for a 4x6 borderless print at 28 seconds on fastest print speeds.

The scanner is great for scanning documents and allows you to scan to application or to a memory card. The paper tray holds 100 sheets of standard paper with a sliding tray for photos that can hold 20 4x6 sheets. In addition to 4x6 prints, you can print up to 8x10 shots as well using the main paper tray. Business users will like the optional duplexer that allows automatic double sided printing. An optional Bluetooth attachment is also available for wireless printing.
The copy function allows you to scale the output from 20% to 500% of the originals size. Copying sheets is fast and the printed output is sharp and legible. A memory card reader on the front panel accepts SD, XD, Memory Stick and CF cards. The Kodak EasyShare 5300 All-in-One Printer has a 3” LCD display that allows you to see images on a memory card and print them without needing a computer. A USB port on the front panel allows printing from PictBridge enabled cameras and USB drives as well. You can perform very limited editing function on the printers LCD screen which amount to zooming and rotating images.
Using the Kodak 5300 All-in-One
In use I printed a 4 x 6 borderless print of my daughter on best photo quality setting and it took 38 seconds on Kodak Premium Photo Glossy paper. Kodak’s print speeds are quoted in the fastest print speeds, so you expect best quality to take longer. The photo looked fantastic and was dry and ready to be handled as soon as it left the printer.
Printing paper documents on best print setting in black with a few blue highlights took 27 seconds. Printed output was sharp and very legible. I also scanned a few documents to memory card. The scanned output was exceptional with crisp letters and no distortion or noise in the documents. The only real problem I had with the Kodak EasyShare 5300 All-in-One Printer was that using the limited editing functions was a bit difficult. I could zoom in on a photo easily. However, when I decided I liked the original photo better, I could not get the printer to zoom back out so I could print the entire photo without removing the memory card and starting over.
Overall, the Kodak EasyShare 5300 All-in-One Printer is a great printer. It uses cheap inks that still have every bit of the quality of much more expensive print systems. You will pay more to get the Kodak EasyShare 5300 All-in-One Printer than you will for competitor’s products, the 5300 sells for $199. The first time you have to buy ink though, the extra cost upfront will be a distant memory.
Kodak’s middle of the road printer is what we are having a look at today. The Kodak EasyShare 5300 All-in-One Printer copies, scans, and prints just as you would expect an all-in-one to do. The biggest feature of the 5300 is the ink prices. Kodak moved the print head from the cartridge into the printer which allowed them to make inks much less expensive. You can get the black ink cartridge for $9.99 and the color ink cartridge costs $14.99. A kit with both cartridges is $22.99. The Epson RX700 I bought a year or so back takes six separate ink cartridges with each color cartridge costing $12.99 and the black cartridge costs $17.09. It cost me $64.95 for the color cartridges alone, when I could find them.
The print quality of the Kodak EasyShare 5300 All-in-One Printer is every bit as good as any photo printer I have used. Photographs have vivid colors, prints are smudge-proof and skin tones are realistic. You can’t tell the difference between prints form the Kodak EasyShare 5300 All-in-One Printer and ones I developed professionally. The printer can put out black document pages at 32 ppm and Kodak quotes print time for a 4x6 borderless print at 28 seconds on fastest print speeds.

The scanner is great for scanning documents and allows you to scan to application or to a memory card. The paper tray holds 100 sheets of standard paper with a sliding tray for photos that can hold 20 4x6 sheets. In addition to 4x6 prints, you can print up to 8x10 shots as well using the main paper tray. Business users will like the optional duplexer that allows automatic double sided printing. An optional Bluetooth attachment is also available for wireless printing.
The copy function allows you to scale the output from 20% to 500% of the originals size. Copying sheets is fast and the printed output is sharp and legible. A memory card reader on the front panel accepts SD, XD, Memory Stick and CF cards. The Kodak EasyShare 5300 All-in-One Printer has a 3” LCD display that allows you to see images on a memory card and print them without needing a computer. A USB port on the front panel allows printing from PictBridge enabled cameras and USB drives as well. You can perform very limited editing function on the printers LCD screen which amount to zooming and rotating images.
Using the Kodak 5300 All-in-One
In use I printed a 4 x 6 borderless print of my daughter on best photo quality setting and it took 38 seconds on Kodak Premium Photo Glossy paper. Kodak’s print speeds are quoted in the fastest print speeds, so you expect best quality to take longer. The photo looked fantastic and was dry and ready to be handled as soon as it left the printer.
Printing paper documents on best print setting in black with a few blue highlights took 27 seconds. Printed output was sharp and very legible. I also scanned a few documents to memory card. The scanned output was exceptional with crisp letters and no distortion or noise in the documents. The only real problem I had with the Kodak EasyShare 5300 All-in-One Printer was that using the limited editing functions was a bit difficult. I could zoom in on a photo easily. However, when I decided I liked the original photo better, I could not get the printer to zoom back out so I could print the entire photo without removing the memory card and starting over.

Vista and PC Audio
How Changes By Microsoft Affected PC Audio
In the early years of computers, audio consisted of just a few series of beeps to simulate music and sound. Of course today we have multichannel surround sound with environmental effects. Then Microsoft went and rewrote the rules of audio on the PC with the Vista operating system. You may have already experienced this if you are running the new OS, but if you are thinking of upgrading your operating system or buying a new PC and audio is important then you need to know about the issue.
What Changed And Why
In previous versions of Windows, hardware audio support was developed as a means of improving the audio output and reducing the strain of audio processing by the CPU. In order to do this, the audio drivers allowed the sound hardware to tie into the kernel level of the operating system. This had unintended consequences that could reduce the stability of the whole OS. One driver error could cause the whole OS to lock up or even worse, blue screen.
In order to increase stability and security in the Vista operating system, audio processing was removed from the kernel level and moved to the user space similar to standard applications. What this meant is that direct hardware calls could not be done and must be handed by a software application. If there is now an issue with the audio software under Vista, only the audio application would be affected while the remaining OS will continue to function.
The Resulting Problem
Since all audio under Vista now runs through a software application at the user level, hardware acceleration has essentially be rendered useless. This is particularly true for any application that was written using the DirectSound3D audio calls or the Creative EAX audio extensions. Games or applications that were written to use these features are now handled by a software interpreter for the new audio stack. Positional audio is still possible, but environmental effects are lost. In some cases, the application may even fail to use positional audio and have only basic stereo output.
Now, for someone that was just using their PC computer to listen to digital audio tracks that were only stereo, such as MP3s, this doesn't really have much of an impact. What they may not know is that the audio hardware previously offloaded this audio processing away from the CPU. Much of that processing has returned to the CPU level under Vista. This is maybe a few percentage points on the CPU usage, but it can still make a difference. Direct3D positional audio with effects causes an even greater impact.
Vista Audio Solution
The industry knew about these changes from Microsoft well in advance of the release of Vista. Thankfully, Creative and Apple picked up development of a solution that was originally developed for use with the Linux operating system. A company called Loki Entertainment developed a platform called OpenAL as a means to provide cross platform hardware accelerated audio. Thus, an application written to use OpenAL could have full positional audio along with environmental effects whether the application was run on hardware used with Windows, OS X or Linux. Loki didn't survive, but their API was continued after they dissolved.
The only drawback to this new OpenAL system was that it requires both the audio hardware and the applications to be written with the API. There are a number of game engines that were developed with this in mind, but that still requires the hardware support. If both of these exist, then full hardware audio acceleration and environmental audio extensions will exist.
What It All Means
Hardware accelerated audio is still possible with Windows Vista, it just encountered a bit of a slowdown. Certain older games may have lost much of their audio processing and unless they are patched by the publishers (something not likely to happen) will not experience anything more than stereo audio in Vista. The main thing is that some existing games and future audio development with hardware audio acceleration is possible with the proper software and hardware.
If you are looking at purchasing a new computer with Windows Vista installed on it or are looking to upgrade to Vista with an existing system, is is important to look closely at the audio hardware on the computer. Check with the manufacturers to ensure that the hardware has compatible OpenAL drivers. This is the only way to experience the full audio potential within Vista. If not, get used to stereo audio output.

Top 5 23-Inch and Up Widescreen LCD Monitors
Widescreen displays are quite popular for notebook computers, but they are still quite limited for desktop systems. They are great for those looking for extra workspace without using dual monitors or for video playback. Here are my selections for the best format widescreen LCD monitors 23" and larger based upon my research and experience.
1. Dell UltraSharp 3007WFP-HC 30"
Dell's UltraSharp 3007WFP monitor set a lot of standards for the large computer monitor market. For one it made the huge screens much more affordable. They have gone and improved on that monitor by replacing the backlighting on it to provide an increased color gamut supported by the monitor. The result is the 3007WFP-HC that provides some of the best color support available on the market. The screen retains its 2560x1600 resolution that requires a Dual-Link DVI graphics card to use. It also has the built-in 4 port USB hub and media card reader.
2. Apple Cinema HD 30"
Apple set the standard for large widescreen monitors with the release of its Cinema displays. It continues to produce some supperb, if pricey computer screens on the market. The Cinema HD 30" screen provides some of the best and most minimalistic screens available on the market. Its excellent brushed aluminum frame is just amazing to see in action. Like the Dell, it features a 2560x1600 resolution that requires a compatible dual-link DVI graphics card. Unlike the Dell screen though, it does feature as many connectors or features beyond this. It does have two USB 2.0 and two FireWire 400 ports for peripherals though.
3. Samsung SyncMaster 275T 27"
30" screens are great, but they do have their problems. You have to have the desk space and graphics card to use them. Then there is the small pixel size that can be difficult to read. 27" screens are a great alternative for those wanting a large screen but don't have what it takes for a 30". Samsung's SyncMaster 275T offers a large amount of screen space with the more universal 1920x1200 resolution. This makes the screen easier to read but still provide plenty of workspace. With superb contrast ratio, brightness and response times, this is one screen you definitely want to look into. Supports DVI, VGA, component, composite, s-video inputs and has built-in speakers.
4. Dell UltraSharp 2407FPW-HC 24"
The UltraSharp 2407WFP-HC is very similar in design and features to that of the UltraSharp 3007WFP-HC but in a smaller package. Based on the previous 2407WFP model, it features the improved backlighting to add in the wider color gamut that is very important for those working with computer graphics. All of this with it's exceptional contrast ratio, brightness and response times. It features DVI, VGA, Component, Composite and S-Video inputs. It also features a four port USB 2.0 hub and a media card reader.
5. HP LP2465 24"
HP is one of the largest computer companies in the world, but it hasn't really been known for making monitors. The HP HP2465 provides people with the option for a solid computer monitor without all the extra connectors and components that generally go unused. It's 1920x1200 screen resolution provides plenty of space with a strong 1000:1 contrast ratio and 500 cd/m2 brightness rating. it can be used with either a DVI or VGA graphics card, but doesn't have any of the more traditional video connectors for TV and DVDs. It does support a 4-port USB hub for easy peripheral connections.

Top 5 Widescreen 20 to 22-inch LCD Monitors
Widescreen displays are quite popular for notebook computers, but they are still quite limited for desktop systems. Thankfully the smaller widescreen monitors are becoming much more common and affordable. Here are my selections for the best 20 to 22 inch widescreen LCD monitors based upon my research and experience.
1. Gateway FPD2275W 22"
22-inch screens are now coming down in the price close to the 20-inch screens and the Gateway offers and excellent value and is packed with features. The display features the traditional 1680x1050 with a good level of brightness and contrast. It also comes with a wide variety of connectors including DVI, VGA, Component, Composite and S-Video with picture-in-picture possible. The screen also comes with a 4-port USB 2.0 hub for connecting extra peripherals to your PC. The EZ-Tune software is its only real problem and can be problematic for Vista users. Of course, most video card drivers allow the same adjustments as the Gateway software.
2. Dell UltraSharp 2007WFP 20.1" LCD
Dell's UltraSharp 2005WFP monitor was extremely popular and successful. Dell has updated this monitor with the new 2007WFP model. It has an updated case that is styled much like their 30" LCD monitor. This is particularly a strong choice for those looking for a small widescreen display with great color and brightness. Response times are quick and able to handle fast motion or graphics. Ports include a DVI with HDCP support, VGA, composite and S-Video. Also included is a 4-port USB 2.0 hub. Dell also offers an option 10W speaker bar that can be attached to it.
3. NEC MultiSync LCD225WXM 22"
NEC's 22-inch widescreen LCD screen doesn't offer as many connectors as some of the other screens on this list, but then again most people only use their monitor with a single PC. What the MultiSync LCD225WXM does offer up instead is a higher 1000:1 contrast ratio that is higher than many in this segment and it does this without sacrificing the refresh rate. It also offers in some integrated speakers for those who want to clean up their desktop of clutter. A solid monitor without all the frills.
4. Samsung SyncMaster 226BW 22"
Many people are amazed by the Samsung SyncMaster 226BW screen. In particular, it does an exceptional job at display quick motion without the tearing or ghosting. This is due to its 2ms grey-to-grey response time rating. Brightness and contrast is on par with other 22-inch LCD screens. The drawback is that the screen does lose some color depth as it uses a 6-bit panel and dithers colors. It features both a DVI and VGA connector for hooking it up to a PC. Overall a great screen for those looking at heavy PC gaming or video work.
5. HP L2045w 20"
Some might be surprised to see HP on this list, but they have actually begun producing some very good quality monitors for the price. Take the L2045w 20-inch screen for example. While it doesn't offer a wide range of connectors or features, it works very well for the price. The has a lower 600:1 contrast ratio, but it does provide the same brightness levels and good response times. It features a DVI and VGA connector as well as a two port USB 2.0 hub. One thing that users need to be aware of is that it does not come with a DVI cable.
1. Gateway FPD2275W 22"
22-inch screens are now coming down in the price close to the 20-inch screens and the Gateway offers and excellent value and is packed with features.

What Computer Should I Buy?
A Questionnaire to Help Determine the Right Computer
This is the most common question that people have when they visit the About PC Hardware / Reviews site is "What Computer Should I Buy?". In order to better answer this question, this questionnaire has been put together. Through questions about budget, computer applications and usage, it will try to determine the best computer to match your needs.
What to Expect
The questionnaire will range between 10 and 13 questions in length. Each question is presented as a single web page with either single or multiple answers. Single answer questions will automatically load the next question. Multiple choice questions will require the selection of all relevant answers followed by the "Next" button to move to the next question.
Some questions may also contain some additional text between the question and answers to clarify what is being asked.
Once all of the questions are answered, a results page entitled "Your Chosen System" will be displayed. On this page will be two sections. The first section will name the category of computer that best suits your usage and budget. Following this will be a link to a selection of the best computers that match this category of computer. For most people, this is all they will need.
The second section will present a set of recommended specifications presented in a table. This will break down the specifications by category and recommended items to look for. Some of the entries in the table will have links to more detailed information or selections about the given specification.
All links presented on the results page are designed to open the relevant page in a new window so it is not necessary to constantly move back and forth between your results and additional information.
Disclaimer
While a lot of effort was put into this questionnaire, there will be some instances where the results may not be what you expect. In most cases, this will be due to the differences in the budget and the intended use of the computer. Many of the most advanced computing tasks such as gaming or desktop video will require more expensive equipment not found in the budget systems or even some of the more mainstream computers. Thus, a computer listed in the best selection for the category may not have all the features listed in the recommended specifications.
Requirements
In order to go through this questionnaire, you will need to be running a browser that has JavaScript turned on. If this function is turned off, the first question will be displayed, but you will be unable to answer the question or continue on to the other questions.

Connect Two Home Computers for File Sharing
Methods for networking two computers
The simplest kind of home network contains exactly two computers. You can use this kind of network to share files, a printer or another peripheral device, and even an Internet connection. To connect two computers for sharing these and other network resources, consider the options described below.
Connecting Two Computers Directly With Cable
The traditional method to network two computers involves making a dedicated link by plugging one cable into the two systems. Several alternatives exist for networking two computers in this manner:
* Ethernet crossover cable
* Null modem serial cable or parallel peripheral cable
* Special-purpose USB cables
Ethernet - Of the above choices, the Ethernet method is preferred as it supports a reliable, high-speed connection with minimal configuration required.
Additionally, Ethernet technology offers the most general-purpose solution, allowing networks with more than two computers to be built fairly easily later. If one of your computers possesses an Ethernet adapter but the other has USB, an Ethernet crossover cable can still be used by first plugging a USB-to-Ethernet converter unit into the computer's USB port.
Serial and parallel - This type of cabling, called Direct Cable Connection (DCC) when using Microsoft Windows, offers lower performance but offers the same basic functionality as Ethernet cables. You may prefer this option if you have such cables readily available and network speed is not a concern. Serial and parallel cables are never used to network more than two computers.
USB - Ordinary USB cables must not be used to connect two computers directly to each other. Attempting to do so can electrically damage the computers! However, special USB cables designed for direct connection exist that can be used safely. You may prefer this option over others if your computers lack functional Ethernet network adapters.
To make dedicated connections with Ethernet, USB, serial or parallel cables requires
1. each computer have a functioning network interface with an external jack for the cable, and
2. the network settings on each computer appropriately configured
One phone line or power cord cannot be used to directly connect two computers to each other for networking.

Jabra JX10 Bluetooth Headset Review
The Bottom Line
The Jabra JX10 has great call quality and is comfortable to wear for most users. The JX10 is also small and stylish and allows you to use both your hands in the car or in the office rather than holding your phone to your ear. If you are looking to shed your clunky VOIP headset and go hands free the Jabra JX10 is a great way to do that.
Pros
* Can work with PC VOIP
* Great call quality
Cons
* Users with small ears may find it uncomfortable to wear
Description
* Should work with most PCs and notebooks via Bluetooth dongle for VOIP.
* Lightweight, stylish and comfortable headset frees both your hands for typing at the desk or driving in your car.
* Jabra even made the charge cradle attractive with the JX10.
Guide Review - Jabra JX10 Bluetooth Headset Review
If you are into using VOIP via your computer you may not realize that with a Bluetooth dongle for your computer or notebook that you can use a Bluetooth headset like the Jabra JX10 to make calls via your computer. The cool part is that by doing this you can make calls on your PC and your cellular phone with one headset.
The Jabra JX10 is a very cool looking Bluetooth headset that is small and comfortable to wear yet doesn’t give up call quality for the sake of small size. For testing the Jabra JX10 I used my PC and Skype as well as my Motorola Razr cellular phone.
The JX10 is an in the ear design with a clip that goes around your ear for added security. The earpiece weighs in at a mete 10 grams, which is 1/3 of an ounce, and it is less than 1.5” in length. Once you get the JX10 in your ear you quickly forget you are wearing it.
Jabra uses DSP technology to automatically control the volume of the JX10 to match the environment you are calling from and reduce background noise, and it does this very well. Controls on the top of the JX10 allow you to answer calls from your cellular phone and allow for one touch paring of the JX10 to your PC or your phone.
Talk time is up to six hours and up to 200 hours on standby. You can charge the JX10 via your PC USB connector or a desk cradle. Jabra also made the charge cradle attractive, which is a change, form the cords you normally see with Bluetooth headsets.
In my testing I had no problem synchronizing the JX10 to my Acer TravelMate notebook via the internal Bluetooth receiver. Call quality was as good with the Jabra JX10 with VOIP as it is with my dedicated PC headset. The Jabra JX10 feels good in the ear and is comfortable for extended use. I found call quality to be fantastic whether I was in my office using VOIP or in the car talking on my cellular phone.

Top 5 Mainstream Desktop PCs
Mainstream desktop PCs are those that fall in the middle of the price range between those considered to be in the budget or performance categories. In general, these systems will provide the best overall value for your dollar. Systems in this category will cost under US$1600 with a monitor or US$1250 without one. All picks are based upon my research and experience.
1.Gateway GM5478
Gateway's retail products have come a long way and offer some spectacular value. The GM5478 is a strong mix of performance and features that also carries a very attractive price. Its Intel Core 2 Quad Q6600 quad core processor is great for those looking to multitask or do lots of video editing. The 500GB of hard drive space provide plenty of storage space and come in handy with its analog and digital TV tuner. It even comes with a decent GeForce 8500 GT graphics for those looking at some casual PC gaming. Overall a very strong value.
2.HP Pavilion m8120n
It was tough call for the top spot as the HP Pavilion m8120n just missed out to the Gateway. Overall, the build quality of the HP system was a bit better, but the difference in price and features in the end dropped it to second. Like the Gateway, it has a Core 2 Quad Q6600 processor but it comes with 3GB of memory and 640GB of total storage space. This makes it slightly better for those doing the digital video and multitasking. Its downfall comes from the older GeForce 7350 LE graphics board that lacks Direct X 10 or much 3D performance. So really, it comes down to a choice of casual gaming and price versus more memory and storage.
3.Dell Inspiron 530
Dell's new Inspiron 530 desktop systems are more geared towards the budget segment, but it is still possible to configure it to be competitive with their own XPS 410 desktop. For those willing to spend a bit more, you can get a Core 2 Duo E6550 processor, 2GB DDR2 memory, 320GB hard drive and a GeForce 8600GT graphics card. The best part is that the systems often come with the Dell line of LCD panels that are some of the best available on the market. Definitely a choice for those looking for a solid all around system, or a budget system if so inclined.
4.Velocity Micro Vector GX
The Vector GX system is qutie a bit older than other desktop systems on this list, but Velocity Micro has done a good job on keeping the specifications competitive. In fact, they now offer three different "versions" of the system. One for home offices with Intel processors, another with AMD processor and a Campus Edition. Of these, the Campus Edition offers the best choice of components and features including a Core 2 Duo E6320, 2GB DDR2 Memory, 250GB hard drive and GeForce 8600 GT graphics card.
5.ABS Ultimate I-Spirit E6400
ABS is generally known for custom built PCs, but for those that need a system without the wait or don't care as much about selecting which components will be used ABS has introduced their new Ultimate Spirit desktops. The I-Spirit E6400 is based off the Core 2 Duo E6400 that provides a solid amount of performance for the price. Users do only get a single gigabyte of memory, 250GB of hard drive space and an older GeForce 7600 GT. What they do get is a very reasonably priced desktop PC system that is several steps above the budget oriented desktops without breaking the bank.

ABS Ultimate I-Spirit E6400 Ready-To-Ship Desktop PC
The Bottom Line
For those looking for a desktop computer system with a bit more power than what is found in the budget systems but don't want to go through the hassle of customizing it to their needs, ABS's new Ultimate I-Spirit E6400 desktop PC offers a solid general purpose computer without the frills.
Pros
* Relatively Low Cost
* Dedicated Graphics Card
Cons
* Would Run Smoother With Two Gigabytes RAM
* Smaller Hard Drive
* No Software Bundle
Description
* Intel Core 2 Duo E6400 Dual Core Desktop Processor
* 1GB PC2-5300 DDR2 Memory
* 250GB 7200rpm SATA Hard Drive
* 18x DVD+/-RW Dual Layer Burner with LightScribe
* NVIDIA GeForce 7600 GT Graphics with 256MB Memory
* Intel HDA Audio
* Gigabit Ethernet
* Six USB 2.0, One FireWire
* Windows Vista Home Premium
Guide Review - ABS Ultimate I-Spirit E6400 Ready-To-Ship Desktop PC
The new Ultimate Spirit line of desktop PCs is a big departure from ABS's normal business. Instead of highly customizable systems, the Spirit come preconfigured for quick shipping and better retail placement. The I-Spirit E6400 is a low cost mainstream desktop PC that strikes a good balance between cost and performance.
The system is based around the Intel Core 2 Duo E6400 dual core desktop processor. This is one of the original Core 2 Duo desktop processors that provides a good amount of performance but is slightly below what most companies offer in their mainstream desktops. It is matched up with 1GB of PC2-5300 DDR2 memory. It would be nice to see ABS include 2GB for smoother performance with Vista, but it is an easy and inexpensive upgrade after purchase.
Storage is alright. The 250GB hard drive is a bit small compared to the 320GB drives used in most other desktop systems. It should provide plenty of storage space unless you expect to be doing a lot of desktop video work. The 18x dual layer DVD burner is quite standard, but it does include LightScribe support for burning labels directly to compatible media.
One area that budget systems tend to fail on is graphics. Their integrated graphics can't handle much in terms of 3D especially when it comes to PC gaming. ABS includes an older but still viable GeForce 7600GT graphics board with the I-Spirit E6400. It doesn't support Direct X 10 and has limited ability for filters, but is great for casual gamers.
The I-Spirit E6400 is a great option for those looking for a bit more out of a computer than what the budget systems offer. It is also a good platform for those looking to add upgrades after the purchase.

Alienware Aurora 7500 Desktop PC
The Bottom Line
Alienware's Aurora 7500 is well suited for those looking for a customizable gaming system. The problem is the base cost of the system makes it difficult to get any options that will make it more competitive with other mainstream desktops in the same price range.
Pros
* Good Dedicated Graphics Card
* Many Upgrade Options Available
Cons
* Only One Gigabyte Memory
* Smaller 250GB Hard Drive
Description
* AMD Athlon 64 X2 4600+ Dual Core Desktop Processor
* 1GB PC2-6400 DDR2 Memory
* 250GB 7200rpm SATA Hard Drive
* 20x DVD+/-RW Dual Layer Burner
* NVIDIA GeForce 8600 GTS Graphics with 256MB Memory
* Integrated 7.1 Audio
* Dual Gigabit Ethernet
* Eight USB 2.0, Two FireWire, One FireWire 800
* Windows Vista Home Premium
Guide Review - Alienware Aurora 7500 Desktop PC
Alienware's Aurora 7500 is probably the least expensive model desktop they offer, and yet it's base configuration barely makes it into my mainstream desktop category. This means that users who want any customization or upgrades will quickly add to the cost of the system.
The Aurora line of desktops is based upon the AMD Athlon series of processors rather than the Intel Core models. The base configuration for the Aurora 7500 comes with the Athlon 64 X2 4600+ dual core processor. This is a fine processor with a long history, but it does fall behind in many performance metrics compared to similarly priced Intel processors. The big drawback though is the base 1GB of memory included with the system. It would be nice to see the base include 2GB as programs run much smoother with that in the Vista OS.
Storage is decent, but falls slightly behind what is offered in most mainstream desktops. The 250GB hard drive falls below the more standard 320GB drive in competing systems. It is possible to upgrade this but that adds to the cost. A faster 20x dual layer DVD burner is included though for handling CD and DVD media.
Graphics is where the Aurora 7500 does outshine most mainstream system. The GeForce 8600 GTS graphics card can handle 3D gaming alright. It definitely is a step up from what most mainstream desktops are using. Those series about gaming will want a higher 8800 series processor though.
What this means is that the Aurora 7500 is probably a good system for those that want to do PC gaming but have a tighter budget. As a mainstream general purpose PC, it probably is not the best choice on the market.

Guide Review - Dell Inspiron 530 Mainstream Desktop PC
Dell's first Inspiron desktop computer system really is geared more towards the budget oriented consumer than the performance minded. That doesn't mean the Inspiron 530 can't be configured as a mainstream PC, it just means that it requires more customization.
The highest level of processor currently offered on the Inspiron 530 is the Intel Core 2 Duo E6550 dual core. This is actually a quite powerful desktop processor and is a step up from what many other companies are offering in their mainstream PCs. One gigabyte is offered standard, but users are advised to opt for the 2GB of PC2-5300 DDR2 memory so that applications run smoothing in the Windows Vista operating system.
There are a wide range of storage options for the Inspiron 530, but most users will probably find sufficient space with the base 320GB 7200rpm hard drive. Large 500GB hard drives or multi-drive configurations are available if you need more. A standard 16x dual layer DVD burner comes standard.
What Dell does offer with the Inspiron 530 that many other companies don't include is a monitor. In the case of this unit, the SE198WFP 19” widescreen is included. While not as nice as the UltraSharp, it still is a decent monitor. The upgrades GeForce 8600GT graphics is also a nice option for those potentially looking to use their system for PC gaming. Although not really powerful, it can still handle the task.
Overall, the Inspiron 530 desktop is a very strong offering, but consumers will need to put up with the customization processor to get the system that they want.
Dell's Inspiron 530 desktop is a very flexible system that can be configured as a low cost budget system or as a mainstream system. In terms of those looking for a moderately priced performance system, it has potentional for those willing to go through the process of customization and parts selection to get it configured just right.
Pros
* Strong Dual Core Processor
* Decent Dedicated 3D Graphics Card
* Includes 19" Monitor and Speakers
Cons

LTB Audio Q-Bass 2.1 Wireless Headphones Review
The Bottom Line
I haven’t used a set of headphones with bass levels as good as those of the LTB Audio Q-Bass 2.1 Wireless Headphones in a long time and have never had a wireless set of headphones perform this well. The levels of bass produced by these headphones are very impressive, yet the bass doesn’t overwhelm the other aspects of your music or movies. If you are looking for a good set of headphones for movie watching, gaming or VOIP you should seriously consider the LTB Audio Q-Bass 2.1 Wireless Headphones, they are hard to beat.
Pros
* Great wireless range
* Fantastic bass
* Mic works well for VOIP
Cons
* Ear cups could use thicker padding
* Poor positional audio when gaming
Description
* Wireless range and sound quality are fantastic.
* The ear cups could use thicker padding for added comfort.
* These headphones have the best bass levels I have heard in a long time.
Guide Review - LTB Audio Q-Bass 2.1 Wireless Headphones Review
The LTB Audio Q-Bass 2.1 Wireless Headphones are a wireless set of headphones that use 2.4 GHz technology for a range of up to 30 meters. I was able in testing to get 50 feet from the transmitter before I lost the signal. The headphones have a diversity antenna using GSFK modulation for improved reception and the tech works. Wireless range is simply fantastic.
The LTB Audio Q-Bass 2.1 Wireless Headphones have levels of bass that you just don’t hear from headphones of any sort. The bass sounds great when watching movies and listening to music. Gaming with the headphones was good too from a bass perspective, but positional audio isn’t great. You really have to get into 5.1 surround sound headphones to get decent positional audio quality.
The headphones are powered by an internal rechargeable battery that charges via USB. The transmitter plugs into your USB port as well. The LTB Audio Q-Bass 2.1 Wireless Headphones require no drivers to operate. I simply plugged them into my PC and they were recognized and worked immediately.
The tiny internal mic works surprisingly well for VOIP chats and gaming. Everyone in the room could clearly hear me, and I could clearly hear them. The mic even did a good job of filtering out background sounds in the room. The left ear cup has the power button, volume controls and pairing button. The ear cup padding was the only other source of irritation for me. My ears touched the inside of the speakers and it was uncomfortable. A bit more padding there and these headphones would be nearly perfect.

Logitech VX Nano Cordless Laser Mouse for Notebooks Review
The Bottom Line
After spending time with the Logitech VX Nano there is no doubt that it is amongst the best notebook mice available. The VX Nano even beats the Logitech VX Revolution by using similar technology, but with more polished. The VX Nano is simply a superb mouse for notebook users.
Pros
* Very compact
* Tiny wireless receiver
* Long battery life
Cons
* Navigation buttons are in an odd location
Description
* The position of the navigation buttons means you use your index finger rather than your thumbs to activate them.
* The navigation buttons are positioned so they are difficult to reach.
* The Nano receiver can be stored under the battery door when you want to unplug it.
Guide Review - Logitech VX Nano Cordless Laser Mouse for Notebooks Review
Logitech introduced a new notebook mouse recently called the Logitech VX Nano. The Nano uses the same scroll wheel as the Revolution VX. The free wheel mode makes scrolling long web pages or documents fast and easy. Unlike the VX Revolution, the VX Nano doesn’t require that you pick the mouse up to change from click scroll to free wheel mode,you simply click the scroll wheel to change click modes on the Nano.
The Logitech VX Nano uses a wireless receiver that only protrudes 7mm from the side of your laptop when plugged in. This Nano wireless receiver design means that you don’t have to unplug the receiver to store or move your laptop.
The Nano has 800 dpi resolution, which is very typical of standard use mice. The laser engine is very accurate and tracks well on any surface but mirrors and clear glass. Wireless reception from the mouse to the Nano receiver is fantastic and in testing I could get about 30 feet from the receiver without loosing connectivity.
Logitech claims the included pair of AA batteries will last for up to six months of use, though heavy users will undoubtedly see less battery life. The Logitech VX Nano has a quick search button under the scroll wheel that goes to your favorite search engine with a button press. The scroll wheel has left and right click functionality and a pair of keys for navigating web pages is located to the left of the left mouse button.
In use the Logitech VX Nano is great, the sensitivity is enough for most users, mobile gamers will want more sensitivity though. The tiny Nano receiver is how wireless receivers should be sized and the ambidextrous design feels great in the hand. You can reprogram all the keys to other functions in SetPoint save the right and left main buttons and the scroll wheel click. Logitech also includes a padded carry bag to help keep the Logitech VX Nano safe during travel.

Gateway GM5478 Desktop Personal Computer System
The Bottom Line
Gateway tried to pack a lot of features into the Gateway GM5478 and it succeeds for the most part. It certainly will provide an excellent experience for those working on digital video or heavily multitasking, but it is a bit definicient in terms of its graphics or for those that don't multitask.
Pros
* Quad Core Processor
* Large Hard Drive
* TV Tuner Included
Cons
* Fairly Underwhelming 3D Graphics Card
* Quad Core Processor Won't Benefit Single Tasked Users
* Door Covering Ports On Front Panel Quite Flimsy
Description
* Intel Core 2 Quad Q6600 Quad Core Desktop Processor
* 2GB PC2-5300 DDR2 Memory
* 500GB 7200rpm SATA Hard Drive
* 16x DVD+/-RW Dual Layer Burner
* NVIDIA GeForce 8500 GT Graphics Wiht 256MB Memory
* Digital (HDTV) and Analog TV Tuner
* Intel HDA Audio With Stereo Speakers
* v.92 56Kbps Modem and 10/100 Ethernet
* Six USB 2.0, Two FireWire and 15-in-1 Card Reader
* Vista Home Premium, MS Works 8, Power2Go, McAfee Internet Security
Guide Review - Gateway GM5478 Desktop Personal Computer System
Gateway's GM5478 is the first of their retail line to use the Q6600 desktop processor. This will greatly benefit those users that doing a lot of video work or heavy multitasking. On the other hand, if the system will be used for more single tasked environments, then a different model with a faster dual core processor is probably a better choice. They have included 2GB of PC2-5300 DDR2 memory to let it run the Vista Home Premium OS smoothly.
Most mainstream desktop computers still come equipped with 250 or 320GB hard drives. Gateway includes a larger 500GB hard drive with the GM5478 because the system also comes with an HDTV tuner. This extra space provides some room for the PVR functions that can be used with the tuner. The system also has a slot on the front panel for use with the optional Gateway Portable Media Drive. Optical storage is handled by a dual layer DVD burner that can be used for recording or playback of CDs or DVDs.
While the Gateway GM5478 does feature one of the new NVIDIA GeForce 8500 GT graphics boards that support the Direct X 10 graphics engine of Vista, it still leaves much to be desired. The graphics board does support some accelerated high definition video decoding, but not to the level of those found in the ATI Radeon HD 2600 products. It also does not provide much in terms of 3D graphics acceleration for gaming beyond the most basic of casual PC games.
What the Gateway GM5478 does is put together a very solid desktop PC for those looking to do digital video or heavy multitasking. While it has a few flaws in terms of the graphics, they can easily be compensated with a few upgrades.

HP Pavilion m8120n Mainstream Desktop PC
The Bottom Line
HP's Pavilion m8120n desktop computer system has some very powerful processing and storage capabilities that make it an excellent choice for those working with digital video or heavily multitasking. Having said that, the system is probably not the best choice for those looking to use it in a more single task environment or for 3D graphics.
Pros
* Quad Core Processor
* Lots Of Memory And Hard Drive Space
* TV Tuner Included
Cons
* Limited Graphics Capabilities
* Quad Core Not Useful For Those That Don't Multitask
Description
* Intel Core 2 Quad Q6600 Quad Core Desktop Processor
* 3GB PC2-5300 DDR2 Memory
* Two 320GB 7200rpm SATA Hard Drives
* 16x DVD+/-RW Dual Layer Burner with LightScribe
* NVIDIA GeForce 7350 LE Graphics with 128MB Dedicated Memory
* Digital (HDTV) and Analog TV Tuner

Guide Review - HP Pavilion m8120n Mainstream Desktop PC
HP made a very interesting choice by using the Intel Core 2 Quad Q6600 for the Pavilion m8120n desktop PC. The processor is a major boost for those that heavily multitask or look at doing computer work while also using the PVR features of the system. If the computer won't be used heavily for video or mulitasking, then the processor ends up being slower than a comparably priced dual core system. This should be an important factor when considering purchasing the system.
The Pavilion m8120n comes with a somewhat odd 3GB of PC2-5300 DDR2 memory. This actually gives it a bit more functionality when multitasking and doing digital video than those with just 2GB. The twin 320GB hard drives provide it with plenty of storage space for storing programs and videos. A door on the left side of cases front panel also hides a slot that can be used for HP's portable drive accessory. For optical storage, a LightScribe compatible DVD burner is included.
The one major flaw in the Pavilion m8120n design is its graphics. The GeForce 7350 LE graphics board included is a step up from an integrated package, but it lacks performance for boosting high definition video or 3D gaming. HP should have considered using a new Radeon HD 2400 or 2600 board if they wanted to boost video processing or a GeForce 8600 for 3D graphics instead of the older 7350 used.
While the Pavilion m8120n is not a home theater specific system, the HDTV compatible TV tuner and 802.11b/g wireless networking can allow the desktop to be used as one. It is much better suited as a desktop system with secondary TV functions while working or in the study.

Lenovo ThinkCentre M55p Desktop PC
The Bottom Line
Lenovo's ThinkCentre M55p desktop computer system features a very powerful dual core processor and a solid warranty and service place to go with it. This makes it a great choice for the business, but it sacrifices some other features more geared towards business that make it only an average choice overall for the consumer.
Pros
* Solid Warranty and Service
* Strong Dual Core Processor
Cons
* Small Hard Drive
* Integrated Graphics
Description
* Intel Core 2 Duo E6600 Dual Core Desktop Processor
* 1GB PC2-5300 DDR2 Memory
* 160GB 7200rpm SATA Hard Drive
* 16x Dual Layer DVD+/-RW Burner
* Intel GMA 3000 Integrated Graphics With 256MB Shared Memory
* Intel HDA Audio
* Gigabit Ethernet
* 10 USB 2.0 Ports
* Windows XP Professional
Guide Review - Lenovo ThinkCentre M55p Desktop PC
The ThinkCentre line of computer systems has always been geared towards business rather than consumers, but that doesn't stop Lenovo from also selling them to the average consumer.
One of the big benefits of the business focus is the emphasis on a strong processor at the heart of the system. While most mainstream desktops are featuring either the AMD Athlong 64 X2 or lower end Intel Core 2 Duo E6000 series processors, Lenovo has chosen to use the higher end E6600 model. This gives it a bit more performance than the average mainstream desktop. It is matched up with a single gigabyte of PC2-5300 DDR2 memory that is sufficient given the system uses the Windows XP Professional OS instead of the new Vista.
The drawback here is the lack of storage in the ThinkCentre M55p. Most new desktops come with at least 250GB or more of storage space. Instead this system uses a fairly anemic 160GB hard drive. This may cause storage problems for those doing a lot of multimedia work. At least Lenovo has finally started to equip their desktops with DVD burners rather than the older CD-RW combo or DVD burners in previous models.
Don't expect much in terms of multimedia either. The system uses all integrated audio and graphics that is sufficient for basic computing tasks. This does mean that the system doesn't have sufficient power for advanced 3D graphics, but it can be upgraded thanks to its PCI Express x16 graphics slot.
The end result is a very solid system for business users that don't really need to do any multimedia work. It will work for consumers looking for a general purpose PC, but it will end up costing more for upgrades compared to other systems currently available.

Systemax Vitality DH43IV Desktop PC
The Bottom Line
Systemax's Vitality DH43IV is a set of compromises that will work for some users and not others. In lew of a dedicated graphics processor or a faster processor, consumer get more memory and hard drive space for running and storing applications.
Pros
* Two Full Gigabytes of Memory

Guide Review - Systemax Vitality DH43IV Desktop PC
8/6/07 – Systemax made some interesting choices when putting together the Vitality DH43IV desktop system. Take for example the processor. They use an Intel Core 2 Duo E4400 dual core processor. While this is a decent processor, it has a lower clock speed and bus speed than the E6400 found in many similarly priced systems. On the other hand though, they include two full gigabytes of memory that lets the system run programs more smoothly with the Vista operating system.
While they may have selected some slower processor components, Systemax has provided some fairly strong storage components. Most mainstream desktops still ship with 250 or 320GB hard drives. The Vitality DH43IV comes equipped with a very sizable 500GB drive that provides plenty of storage. This is important because it also comes with a TV tuner that can be used as a PVR that can quickly eat up storage space. A fairly standard 18x dual layer DVD burner is included for reading or recording CDs and DVDs.
One area that the Vitality DH43IV suffers though is in the graphics department. Systemax has decided to use the integrated Intel GMA 3000 graphics processor that users up to 256MB of the system memory. This is fine for general computing purposes, but it does not support Direct X 10 or have sufficient power for even casual 3D gaming. Thankfully the system has a PCI Express x16 graphics cards slot so a discrete graphics card can be installed.
The end results is a compromise on performance and graphics for storage space and PVR capabilities. This may work well for some people but makes the system more specialized then a strong overall choice in a desktop.
Systemax's Vitality DH43IV is a set of compromises that will work for some users and not others. In lew of a dedicated graphics processor or a faster processor, consumer get more memory and hard drive space for running and storing applications.

What is Overclocking?
Introduction
Many people probably don't know what overclocking is but have possibly heard the term used before. To put it in its simplest terms, overclocking is taking a computer component such as a processor and running at a specification higher than rated by the manufacturer. Every part produced by companies such as Intel and AMD are rated for a specific speeds. They have tested the capabilities of the part and certified it for that given speed. Of course, most parts are underrated for increased reliability. Overclocking a part simply takes advantage of the remaining potential out of a computer part that the manufacturer is unwilling to certify the part for but it is capable of.
Why Overclock a Computer?
The primary benefit of overclocking is additional computer performance without the increased cost. Most individuals who overclock their system either want to try and produce the fastest desktop system possible or to extend their computer power on a limited budget. In some cases, individuals are able to boost their system performance 25% or more! For example, a person may buy something like an AMD 2500+ and through careful overclocking end up with a processor that runs at the equivalent processing power as a AMD 3000+, but at a greatly reduced cost.
There are drawbacks to overclocking a computer system. The biggest drawback to overclocking a computer part is that you are voiding any warranty provided by the manufacturer because it is not running within its rated specification. Overclocked parts that are pushed to their limits also tend to have a reduced functional lifespan or even worse, if improperly done, can be destroyed completely. For that reason, all overclocking guides on the net will have a disclaimer warning individuals of these facts before telling you the steps to overclocking.
Bus Speeds and Multipliers
To first understand overclocking a CPU in a computer, it is important to know how the speed of the processor it computed. All processor speeds are based upon two distinct factors, bus speed and multiplier.
The bus speed is the core clock cycle rate that the processor communicates with items such as the memory and the chipset. It is commonly rated in the MHz rating scale referring to the number of cycles per second that it runs at. The problem is the bus term is used frequently for different aspects of the computer and will likely be lower than the user expects. For example, an AMD XP 3200+ processor uses a 400 MHz DDR memory, but the processor is in fact using a 200MHz frontside bus that is clock doubled to use 400 MHz DDR memory. Similarly, the new Pentium 4 C processors have an 800 MHz frontside bus, but it is really a quad pumped 200 MHz bus.
The multiplier is the multiple that the processor will run at compared to the bus speed. This is the actual number of processing cycles it will run at in a single clock cycle of the bus speed. So, a Pentium 4 2.4GHz "B" processor is based on the following:
133 MHz x 18 multiplier = 2394MHz or 2.4 GHz
When overclocking a processor, these are the two factors that can be used to influence the performance. Increasing the bus speed will have the greatest impact as it increases factors such as memory speed (if the memory runs synchronously) as well as the processor speed. The multiplier has a lower impact than the bus speed, but can be more difficult to adjust.
Let's look at an example of three AMD processors:
CPU Model Multiplier Bus Speed CPU Clock Speed
Athlon XP 2500+ 11x 166 MHz 1.83 GHz
Athlon XP 2800+ 12.5x 166 MHz 2.08 GHz
Athlon XP 3000+ 13x 166 MHz 2.17 GHz
Athlon XP 3200+ 11x 200 MHz 2.20 GHz
Let's then look at two examples of overclocking the XP2500+ processor to see what the rated clock speed would be by changing either the bus speed or the muliplier:
CPU Model Overclock Factor Multiplier Bus Speed CPU Clock
Athlon XP 2500+ Bus Increase 11x (166 + 34) MHz 2.20 GHz
Athlon XP 2500 + Multiplier Increase (11+2)x 166 MHz 2.17 GHz
In the above example, we have done two changes each with a result that places it at either the speed of the 3200+ or a 3000+ processor. Of course, these speeds are not necessarily possible on every Athlon XP 2500+. In addition, there may be a large number of other factors to take into consideration to reach such speeds.
Because overclocking was becoming a problem from some unscrupulous dealers who were overclocking lower rated processors and selling them as higher priced processors, the manufacturers started to implement hardware locks to make overclocking more difficult. The most common method is through clock locking. The manufacturers modify traces on the chips to run only at a specific multiplier. This can still be defeated through modification of the processor, but it is much more difficult.
Voltages
Every computer part is regulated to specific voltages for their operation. During the process of overclocking the parts, its possible that the electrical signal will be degraded as it traverses the circuitry. If the degradation is enough, it can cause the system to become unstable. When overclocking the bus or multiplier speeds, the signals are more likely to get interference. To combat this, one can increase the voltages to the CPU core, memory or AGP bus.
There are limits to the amount of additional voltage that can be applied to the processor. If too much voltage is applied, the circuits inside the parts can be destroyed. Typically this is not a problem because most motherboards restrict the possible voltage settings. The more common problem is overheating. The more voltage supplied, the higher the thermal output of the processor.
HEAT!
The biggest obstacle to overclocking the computer system is heat. Today's high-speed computer systems already produce a large amount of heat. Overclocking a computer system just compounds these problems. As a result, anyone planning to overclock their computer system should be very aware of the needs for high performance cooling solutions.
The most common form of cooling a computer system is through standard air cooling. This comes in the form of CPU heatsinks and fans, heat spreaders on memory, fans on video cards and case fans. Proper airflow and good conducting metals are key to the performance of air cooling. Large copper heatsinks tend to perform better and the greater number of case fans to pull in air into the system also helps to improve cooling.
Beyond air cooling there is liquid cooling and phase change cooling. These systems are far more complex and expensive than standard PC cooling solutions, but they offer a higher performance at heat dissipation and generally lower noise. Well-built systems can allow the overclocker to really push the performance of their hardware to its limits, but the cost can end up being more expensive than processor to begin with. The other drawback is liquids running through the system that can risk electrical shorts damaging or destroying the equipment.
Component Considerations
Throughout this article we have discussed what it means to overclock a system, but there are a lot of factors that will affect whether a computer system can even be overclocked. The first and foremost is a motherboard and chipset that has a BIOS that allows the user to modify the settings. Without this capability, it is not possible to modify the bus speeds or multipliers to push the performance. Most commercially available computer systems from the major manufacturers do not have this capability. This is why most people interested in overclocking tend to buy specific parts and build their own systems or from integrators who sell the parts that make it possible to overclock.
Beyond the motherboards ability to adjust the actual settings for the CPU, other components must also be able to handle the increased speeds. Cooling has already been mentioned, but if one plans on overclocking the bus speed and keeping the memory synchronous to offer the best memory performance, it is important to buy memory that is rating or tested for higher speeds. For example, overclocking an Athlon XP 2500+ frontside bus from 166 MHz to 200 MHz requires that the system have memory that is PC3200 or DDR400 rated. This is why companies such as Corsair and OCZ are very popular with overclockers.
The frontside bus speed also regulates the other interfaces in the computer system. The chipset uses a ratio to reduce the frontside bus speed to run at the speeds of the interfaces. The three major desktop interfaces are AGP (66 MHz), PCI (33 MHz) and ISA (16 MHz). When the frontside bus is adjusted, these buses will also be running outside of specification unless the chipset BIOS allows for the ratio to be adjusted down. So it is important to know how adjusting the bus speed can impact stability through the other components. Of course, increasing these bus systems can also improve performance of them, but only if the components can handle the speeds. Most expansion cards are very limited in their tolerances though.
Slow and Steady
Now those who are looking to actually do some overclocking should be warned not to push things too far right away. Overclocking is a very tricky process of trial and error. Sure a CPU may be able to be greatly overclocked in the first try, but it is generally better to start out slow and gradually work the speeds up. It is best to test the system fully in a taxing application for an extended period of time to ensure the system is stable at that speed. This process is repeated until the system does not test fully stable. At that point, step things back a bit to give some headroom to allow for a stable system that has less chance of damage to the components.
Conclusions
Overclocking is a method for increasing performance of standard computer components to their potential speeds beyond the rated specifications of the manufacturer. The performance gains that can be obtained through overclocking are substantial, but a lot of consideration must be done before taking the steps to overclocking a system. It is important to know the risks involved, the steps that must be done to obtain the results and a clear understanding that results will very greatly. Those who are willing to take the risks can get some great performance from systems and components that can end up being far less expensive than a top of the line system.
For those who want to do overclocking, it is highly recommended to do searches on the Internet for information. Researching your components and the steps involved are very important to being successful.

Remember that this is just a guide of recommended products.
There are many alternative components available that will perform just as well. In addition to the name of the item, a link is included for price comparison shopping for the components.
The HTPC PC Components
* Case – Silverstone Lascala LC20
This full size case is designed to blend in with home theater equipment and provides plenty of space for all of the components to be installed.
* Power Supply – Antec Phantom 500W
With noise such an important factor for a HTPC, the Antec fanless 500W power supply is perfect for such a project.
* Motherboard – ASUS P5K-V
This motherboard offers an excellent choice for a HTPC that can fit a standard ATX motherboard thanks to its Intel G33 chipset and passive component cooling.
* Processor – Intel Core 2 Quad Q6600
With HD video streams and multiple video sources, the lower cost quad core processor can really help out with the multitasking in a HTPC.
* Memory – Mushkin PC2-6400 2GB DDR2 Kit
Even though most systems will run smoothly with a single GB of memory, the 2GB kit provides better performance with tasks such as video compression.
* Video Card – Sapphire Radeon HD 2600 XT
Since video is the primary purpose of a HTPC, the video card of choice is the new Radeon HD 2600 XT thanks to its ability to offload high definition video decoding from the CPU. About the only drawback is the lack of an HDMI connector on the current crop of cards.
* Audio Card – Auzentech X-Meridian 7.1
The X-Merdian 7.1 card features Dolby Digital Direct so that it can output 5.1 audio over a standard SPD/IF digital connector for a compatible amplifier or speakers.
* Capture Card (Digital) – AverMedia MTVPEMCER
This PCI-Express x1 card supports both analog and digital HDTV broadcast signals. It also comes with an USB infrared blaster to control cable and satellite receivers.
* CD/DVD – Lite-On LH-20A1S 20x DVD+/-RW Dual Layer
Even though BluRay and HD-DVD drives are available, the prices are still too high. This drive is a realiable low cost model that is great for playback and burning of CDs or DVDs.
* Hard Drive – Samsung SpinPoint T 500GB SATA
Sure, there are larger drives on the market but for the price, the Samsung drive offers lots of space and very little noise. You can always install two if you need more space for video.
* Operating System – Windows Vista Home Premium
Vista Home premium adds in all of the multimedia features once found in the XP Media Center Edition to this new OS.
What Else is Needed
This list of components will make up the heart of the computer system, but it still needs a few parts. Since the system will be use in a living room environment, a wireless keyboard and mouse would probably be the best best for using it from your couch. A good place to start is to check out the About PC Peripherals site. The system is also best hooked up to a high definition TV monitor. So, if you are in the market for a HDTV as well, check out the About TV and Video site.
Putting it All Together
Of course, once you have all the parts, the computer system will have to be assembled and installed. Tutorials on the various steps required to install the parts together into the computer system can be found in one of two ways. I have available a 5-day E-mail Newsletter Course that puts the steps in a logical order or you can just dive right into the individual Tutorials themselves.
ntroduction
Many people don't realize how easy it is to put together a computer system from parts. In fact, many systems that users build can outperform purchased desktop computer systems. The biggest challenge of putting together a computer system is typically finding what parts to buy. That is where this guide comes in.
Analysts had been predicting that computers would become a staple of the living room entertainment system. It wasn't until the past year that this has really become possible thanks to the introduction of HDTV. Now a PC can sit in a media center and act as a computing hub as well as video and audio. These systems are known as home theater PCs or HTPCs. This guide was put together as a a template for those looking to put together a computer to do all these tasks.
