Im have having all sorts of trouble playing all my games such as WOW, Frozen Throne and NFS most wanted. They all freeze and jam up in game every few min. Internet surfing and general computer use is fine. I have tried reinstalling all games and reducing all video options in game to as low as possible and I still get the same problem. I am thinking that maybe its my video card which is a 6800 ultra and has been working fine up to this issue at the moment. Any help would be great.
