Graphical errors

I have been getting alot of graphical errors when switching between my windows in wow lately. I have my settings set at fair-good and I have a 680 video card. Running Direct x11 and have just updated my video drivers. Is this a problem I should be having or is my video card bad? I just don't know what to do anymore, any suggestions would be welcome thanks you.

Getting alot of 'driver has stopped responding' or w/e also. =(

These are not issues you should be having, no. When did it start? Have you tried using GPU-Z or something else that can tell you the temperature of the card? It could be running too hot. (Or it could be a voltage issue, what do I know really)

You can also try changing the fullscreen/windowed mode option in the in-game video settings. ISBoxer will ensure it's in a window no matter what you set it to (either fullscreen, windowed, or fullscreen windowed), but it's possible that a different setting here can eliminate your problem.

Or you can try switching WoW down to d3d9 mode and see if the problem only occurs with d3d11.
