I have had a pc for two years now. It got a virus and I had to do a fresh XP install. Now after I wiped everything with a fresh beginning with the drivers re-installed, I boot up my pc and after about two minutes of running, everything freezes except for my mouse. I can move my mouse but I cant click on anything at all. I bought a brand new hard drive and reinstalled xp and it still freezes after a minute. It's the wierdest thing I've ever seen and I have no idea what to do. Is upgrading my pc with all new parts the only thing i can do?
