Guild Wars 2

I am experiencing exactly the same issue. At first it starts with random quick screen freezes and then you get 1 or 2 second blank screens. Once I wasn’t even able to get back to game.

Updated Windows 7 and the NVIDIA drivers before posting this and checked the issue was still going on.
