Windows has recovered from a serious error?

I just formatted and installed windows xp, with service pack 2, and every possible update microsoft has. I have not installed any hardware, it is the same hardware I've been using for 3 years, the drivers for all my hardware are up to date. I just recently had my computer crash, and finally got it fixed, but after fixing it, the same problems are occuring. The computer keeps shutting down, then I get a message, windows has recovered from a serious error. not only that, but I'll try and listen to my music, with winamp, or windows media player, and they will both "cause unexpected errors" and need to close, I can't even run a game, and I had it almost beat before I wiped out my harddrive, so I have run it before, it just sends me back to the windows desktop, if anyone has any ideas, or advice, I'm lost, please help.
Solution:-My computer did the exact same thing, and they told me that my ati graphics driver was corrupt. I just got a new computer, and didn't fix the old one.
