Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.


1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.





2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.





3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.





4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.





The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.





Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.





Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.





5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.





6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.





7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.





8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.





9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.





10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.





11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.





12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.





13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.





14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.





15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.





16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.





17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.





18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.





19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.





20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.





21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.





22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.





23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.







Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.


Simple Tweaks for Peak PC Graphics Performance




Adjust the settings for your graphics board and display to improve image quality.





When it comes to your PC, looks definitely matter. Tiny text, blurry images, and flickering screens aren't just annoying, they can lead to eyestrain, lost productivity, and a bill from the glazier for replacing the window you toss your monitor through out of frustration. But you don't have to give your display the heave-ho: A few simple adjustments to your graphics card and other Windows settings can ensure peak visual performance.





Your PC's graphics card is controlled by its Windows driver, so get the latest driver release for your board. To see what version you have, right-click the desktop and choose Properties to open the Display Properties dialog box, then click Settings, Advanced, Adapter (in Windows XP, also select Properties, Driver).





Visit your graphics-card vendor's Web site to download the most recent version of the driver, but don't install beta drivers. These are works in progress that may cause more trouble than they're worth.





Sight-Saving Settings





Here are a few settings that should be available for all graphics drivers.





Resolution: This is the number of dots--or pixels (short for "picture elements")--displayed on your screen. The higher the resolution, the more dots per inch, and the sharper the displayed image (if your monitor supports the higher resolution). High resolutions increase the processing demands on your graphics board and PC.





The graphics cards in most computers made in the last three or four years support resolutions of at least 1024 by 768--meaning the screen image is composed of an orthogonal array 1024 pixels across and 768 pixels tall--and some support screen resolutions as high as 1600 by 1200. However, many older systems, as well as some newer budget systems, have a top resolution of only 800 by 600.





To adjust screen resolution, open Display Properties and click Settings. Slide the 'Screen area' or 'Screen resolution' bar to a higher (More) or lower (Less) resolution. Though higher resolutions improve image quality, they also shrink icons, text, and other on-screen objects. Experiment to find the setting that's right for you. For most people, 1024 by 768 is the highest resolution they can read easily on a 17-inch CRT monitor.





Color depth: This setting is the number of colors that your graphics card supports. The more colors available for use, the more realistic the image, but again, the more colors on your screen, the greater the processing demands on your system.





Your graphics card's color-depth settings are listed in Display Properties under the Settings tab on the Colors drop-down menu ('Color quality' in Windows XP). Each is named for the number of bits it assigns to each pixel: True Color (also called 24-bit color) makes 16,777,216 colors available, while High Color (16 bits) supports 65,536 colors. At lower than 16-bit color, your images may suffer. Many drivers no longer offer 8-bit (256 colors) or 15-bit (32,536 colors) settings.





New PCs often support 32-bit color, which offers the same 16 million-plus colors as True Color. The extra 8 bits control image opacity. This is useful in fast-moving 3D games but of little help in most business apps.





Refresh rate: Expressed in hertz, or cycles per second, this tells how often the phosphors that glow to create an image on a CRT screen are reenergized--that is, the times per second that the screen's image is redrawn. A refresh rate that's too low can cause annoying screen flicker. Even if you don't see the flicker, slow refreshes can cause eyestrain and headaches.





Conventional wisdom says your refresh rate should be no less than 72 Hz. Some experts say the minimum rate is 80 Hz. Try different refresh rates until you find the one that works for you. Note that if your refresh rate is too high, you could lose image opacity. Still, few of us can discern rates higher than 85 Hz.





To adjust your screen's refresh rate in Windows XP, open Display Properties and click Settings, Advanced, Adapter, List All Modes. Pick a combination of refresh rate, screen resolution, and color depth from the list of supported values.





To change your refresh rate in other versions of Windows, open Display Properties and then click Settings, Advanced, Adapter. Select an option from the 'Refresh rate' drop-down menu. If you see no options there, however, your graphics board and monitor don't support multiple refresh rates.





Even in that case, you might be able to increase your display's refresh rate by decreasing your screen resolution or your color depth. All three specs compete for graphics-processing capacity, so if your graphics system is running at its maximum, try increasing one setting and lowering another. For example, reducing color depth from 32-bit to 16-bit--no big deal if you never look at photos--may free up enough processing power to let you bump your refresh rate from an annoying 60 Hz to an eye-pleasing 72 Hz. Or you may be able to increase resolution from 800 by 600 to 1024 by 768. There's no guarantee, but these tricks might work.





Windows automatically sets your screen refresh rate to a safe but slow 60 Hz when it can't detect your monitor. To confirm that Windows XP correctly recognizes your monitor, open Display Properties and click Settings, Advanced, Monitor. If your monitor isn't listed under 'Monitor type', download and install the device's driver from the manufacturer's Web site.





In other versions of Windows, verify that Plug and Play is enabled. Make sure your monitor is listed under 'Display' on the Settings tab in Display Properties, and then click Advanced, Monitor. Verify that Automatically detect Plug & Play monitors is checked. If it isn't, select it and then reset your refresh rate to a level that is higher than Windows' default 60 Hz.





DirectX: This Windows component controls multimedia functions. To check your current DirectX version, click Start, Run, type dxdiag, and click OK. Choose the System tab and look under System Information on the lower part of the screen. DirectX 9 is the latest version; if you don't have it, download it from Microsoft.



Touch Those Dials!





You can improve the image quality of your monitor via its built-in controls. The options vary by display manufacturer and model, but you should find brightness and other controls on most monitors.





Adjust brightness and contrast: Use this gray-scale image on your screen. Be sure you can see as many of the image's 17 shades as possible; the two or three darkest may be tough to view in a bright room.





Center and align: Few monitors come straight from the factory with optimal screen geometry. Use your monitor's screen-placement controls to center your displayed image, keep its edges straight, and minimize unfilled screen space.





To avoid eyestrain and other physical problems, put the top of the screen at eye level and at arm's length from your head (your best position may vary). Orient your screen to avoid glare from lights and windows. If that's not possible, get a glare filter such as Kensington's $34 GlareMaster.





Clean it: Gently wipe your screen with a soft, lightly moistened cloth. Unless the monitor is really filthy, avoid cleaning solutions, which can damage delicate screen coatings. Clean the dust from the cooling vents in the monitor's case; overheating is your display's lethal enemy.





Graphics Triage





If your screen goes blank, the problem is likely due to a disconnected monitor cable, an unplugged power cord, or a too-low brightness setting. Monitors do die, however. If you smell something burning or hear popping sounds, your monitor could be failing--turn it off immediately. Monitors have been known to spontaneously combust.





Corrupted graphics drivers cause all kinds of PC problems. To check for a damaged graphics driver, install the plain-vanilla VGA driver that comes with Windows. If your troubles disappear, reinstall a clean copy of the monitor's original driver, or an updated version.





Some graphics boards don't work or play well with other hardware devices. Windows allows you to disable graphics-acceleration functions for the sake of compatibility. Open Display Properties and click Settings, Advanced, Troubleshooting in Windows XP and 2000, or Settings, Advanced, Performance in Windows 98 and Me. Move the slider under 'Hardware acceleration' to the left to disable your graphics acceleration.





A shaking or shimmering image on your screen may be due to nearby magnetic fields. Keep clocks and other appliances that use electric motors, and those that use a lot of electricity (such as microwave ovens), far from your monitor. Power lines behind walls can cause interference, so try moving the display away from nearby walls.





If your screen image is washed in blue, red, or green, check for a loose cable connecting your graphics board to your monitor. Look for bent pins inside the cable connector; you can often straighten them with needle-nose pliers. If on-screen objects have a rainbow cast, some monitors have convergence controls that you can use to tune the image.





Living in a Flat World





Notebook displays are fine-tuned in the factory to work with the system's other hardware; your desktop's flat panel likely isn't. And tuning an LCD isn't the same as tuning a CRT monitor. If both your LCD and graphics board support Digital Visual Interface connections, make sure they're using them. Vendors don't always ship a DVI cable with cards that produce both analog and digital signals, so you'll have to replace the analog cable. If your display supports DVI but your graphics card doesn't, upgrade your card.





Make sure your LCD is set to its native resolution. Many flat-panel displays don't look good at other resolutions. Unfortunately, some 15-inch LCDs have a native resolution of 1024 by 768 dpi, which makes text minuscule. The solution is to open Display Properties, click Appearance, and change the setting on the 'Font size' drop-down menu to increase the size of your text. (Most browsers include their own font-size settings.)





In Windows XP, open Display Properties, click Appearance, Effects, and check Use the following method to smooth screen fonts. Select ClearType to see a big improvement in the appearance of many of your fonts.

PCStats have a new advanced guide out for flashing your video card BIOS! While this *not* something for the novice to undertake, flashing your video card BIOS may lead to performance and feature enhancements.




We recently ran an article on flashing (reprogramming) the BIOS (Basic Input/Output System) of your motherboard to enable new features and fix errors. That got us thinking that we'd only covered half the story. Sure, hardware enthusiasts have been upgrading the BIOS on their motherboards for years, but what about the other components of a computer system?





Here's a snap:





Video cards in particular have an interesting history in relation to the BIOS flashing procedure. While motherboard BIOS fixes generally add support for new processors and fix hardware glitches, video card BIOS updates have the potential to do much more. Enterprising tech-heads have discovered instances where a video card can actually be transformed by a BIOS update, activating hidden features and potential buried performance aspects by the manufacturer (generally for marketing purposes).
