To Keep Your Computer Healthy and Running With Windows 2000 / XP

1. Run Windows Update for Windows XP and 2000. Make sure Internet Explorer and other browsers are updated to the latest versions.

2. Connect your computer to a hardware firewall, or run a free firewall program such as Zonealarm. This will ensure that hackers do not intrude your computer using newly discovered Windows vulnerabilities. If you use a hardware based firewall, make sure that only ports of services you need are enabled (such as web browsing - HTTP is port 80). Many of the firewalls for home use allow all ports to be open by default - you turn off services by entering ranges of ports to be blocked. (See the instruction manual of your firewall).

3. Install adware detection programs, such as Adware or Spybot: Search and Destroy, which are free for download. Run these at least every other day if you are an active web surfer, constantly doing research or shopping online.

4. Run anti-virus software and make sure virus definitions are set to automatically update or you should check for updates, manually. If your anti-virus subscription has run out, uninstall it, and install AVG Anti-Virus by www.Grisoft.com for a free personal edition (Do not run this on your work computer without paying for it!).

5. If you have an older computer, investigate any suspicious "whirring" noises. A harddrive that is making a very loud "whirring" noise may be aging and damaged by heat - consider replacing it soon. Also, make sure that all fans are running properly, inside, and that there are no large collections of dust on the motherboard, PCI cards, or the fans. If so, be very careful in removing it. All power should be turned off, including removal of the power cord, as some motherboards maintain a small charge from the power supply even after the computer is actually turned off.

6. Run the Windows XP / 2000 disk defragmentor once per month. This allows for data files to be stored with each segment next to each other in order, on the disk. Without defragmenting, Windows will store data whereever it finds space, but many times it will store pieces of a data file in many different areas on a hard drive. This is how it was designed. It is faster for Windows to store data in just anyplace it can, without having to think about storing everything close together - that apparently would be too much logic to be used at one time and slow down the immediate saving of files (this is *only* my guess).

7. Make sure programs and drivers are updated. If everything seems to be working, check for driver updates once per year.

8. This is not necessarily related to your computer's health, but before if it ever does get sick, it is good to make sure that you are getting regular backups. Try backing up your My Documents folders and files to a CD every month and carefully label and store it away. If it seems to be too much hassle to burn a CD, try getting a USB memory device and backup your files to this once in awhile, though these are not as reliable as a CD backup (they are prone to problems with static electricity and breakage), they are better than no backup at all.

9. Use a UPS (Uninteruptible Power Supply) to ensure that your computer gets good voltage and is not turned off when the power hiccups. Also, make sure you do not turn off your computer abruptly - always go through the Start button and shutdown or control-alt-delete, click shutdown sequence to ensure that your computer is shut down as graceful as possible.
