I have this really wierd problem with my pc whenever I play games. It only happens when I play games and it had never happened before until a few months ago when it first happened while I was playing oblivion. I thought it might have been just that game but now whenever I play any game it happens. I have all of the recent drivers for all of my hardware (except sp2), but for some reason I'll just be playing a game and the screen will go to a blank blue screen and the sound will get distorted and skip and then I have to restart my pc. sometimes when I'm playing WoW it will just crash back to windows with an error screen instead. this problem also occurs randomly, sometimes after an hour of playing the game and sometimes after about 10 minutes. I've allready asked on other forums and we ran memtest and checked for malware and both checked out ok. whenever I go to my computer, manage and check for errors it says unable to complete operation, interface unknown... so I can't check those. If anyone has had this problem before or has an idea as to how I can fix this I would really appreciate it.
