Windows 7 Pro SP1 4 gig Ram, AMD X6 Processor,550 Watt PSU, lastest video driver installed. I can play Call of duty black ops without problems but when I get on the internet to view a YouTube video or any other little videos I get pink pixels sometimes other colors other times, screen shakes, locks up, then a blue screen. Sometimes it comes back and tells me the video card has recovered from a fatal error. Video card is less than 6 months old. Everything in PC is new. Any idea?
