Hey so wondering if anyone can help me... I have a issue while playing starcraft 2 and diablo 3 that has never happened before. It started randomly lagging and turning black while playing diablo 3 and starcraft 2 . I updated the drivers to the latest on the NVIDIA website... My specific card is ..... NVIDIA Geforce GTX 550 . It will turn black for a few secs then back to the game. then do it again randomly. Is this a over heating problem? here's the message starcraft 2 says... all windows says is it recovered from a video driver error but I uploaded the screen shot what starcraft 2 says after the screen returns from black.
