Hello! I am having some problems with xp and want to reinstall it. I also have SP2 installed. When I put my original XP disk in, I get the message, "setup cannot continue because the version of windows on your computer is newer than the version on the cd". I'm guessing that is because I have SP2 on the computer. If I reinstall XP, will I have to reinstall SP2? And it also said it will change my settings. What settings will it change? I just want to get rid of all the glitches. When I defrag, my computer always freezes and if I leave the computer on overnight, I always have to reset as it has frozen. Thanks for your help.
