I am running 12.6 drivers right now. When I am on my desktop every once in a while ill see a black speck flash on the desktop. Normally towards the upper left corner. Its very strange, I did a reformat and it still appears on occasion. I ran 3dmark 11, heaven, D3, and BF3 and no artifacts. The temps are about 72c load and not OCing the GPU. Anyone experience this bizarre issue?
