So, I've been running 480 sli for some time now. Starting a couple months back every time I boot up the main monitor would become pixelated, as if the card was hot, or overclocked too heavily and would then reset the screen, giving a Nvidia driver blah blah blah has stopped responding. This happens regardless of the driver being used and gpu temps are within the norm for 480 sli. There is also no issues playing games, any thoughts or similar experiences?
