My HD 5850 is running this weird sqaure pattern in the background of several games I am playing. These games are SCII, Diablo 3, and Skyrim. I have reformatted the hardrive and tried to update drivers several times. With Catalyst Control Center, it won't even let me get to the overclocking options any more. So at the moment nothing is overclocked and I reset to default optimized settings on everything. These graphics only appear on certain objects. Is my GPU dieing? Thanks for all your help and suggestions, I have tried to look into this for a while now.
