i had something bugging my pc and causing IE8 and firefox 3 to keep getting bsod and rebooting. after many attempts of fixing it I tried using the xp repair on the cd and when it was done it took out sp 2 and 3. Should I just clean my hard drive and start all over again and reinstall eveything? Now it keeps coming up attempting to reinstall something on its own and getting an installation error that I can't figure out where it is coming from. the pc will boot and I am typing on it it now but its not just right.
