I have been running my 670 for 9 months now without a problem. I could play games such as crisis 3, Borderlands 2, Assassin's Creed 3, without any problems. All of a sudden they now crash the graphics drivers and cause the game to stop responding, any idea as to why? Have tried 320.18, 314.22, and 314.07 whql drivers.
