I need to format my computer because i got a virus and in fixing it and deleting the virus i completely killed my comp. It still starts up but almost all of the progs don't work no more. I'm using windows xp and I've never formatted a computer with xp before. Can anyone tell me how to format my c drive and reinstall windows xp while i have xp as an operating system. And how to make the disk that's needed to format.
