I have this really random/wonky/weird problem that keeps happening on my pc... I'll just be messing around on the internet/listening to music/other random things, and a white screen will come up on my monitor, and my computer freezes. This started happening a few months after I got it, it stopped for a long time, then happened again. The computer has gone through a reformat twice and it still happens on occasion. I'm wondering if anyone has any idea wtf is going on? I know its not a virus, my cousin said it could be a possible video card problem. Here are my computer specs: XP, Service Pack 2 Media Center Edition 2002 Hewlett Packard AMD 3500 64 bit processor 1 Gig of Ram 250 Gig HD ATI Radeon Xpress 200 graphics card. thanks for any input.
