Video card problem?
Ok I'm not sure how to explain this perfectly but starting today I've had this odd problem, I'll be playing WoW and the screen will suddenly change all sorts of different colors and I can't move in WoW, if I alt tab out and go back in it works again, but after that it takes 5 times longer to alt tab than normal, its happened twice today, I don't know what to think. My ram? My video card? It only started today, and its happened twice so far, the alt tab thing taking forever lasts until I restart my computer. My specs are in my sig.
