Many people who have had their computers for 18-30 months now complain of laggy performance and have the dire wish to upgrade. There is a quick (rather long actually) fix to this. Backup Format your harddrive Reinstall Windows XP (don't you dare go back to W98!) Reinstall all of your programs. Any questions? This is a rather primitive guide but thorough > pcmech.com/show/os/70/2 Basically on XP after you have have backedup, you just have to put in the XP disc and restart. Its automated all the way to the finish. (Then you have to reinstall 10 or so programs that you absolutely need) Now you will have a computer without the preinstalled software that you dont need, and be reorganized.
