so, i have two video cards in my pc. and amd 6870 i run full time mining, and my nvidia 560 i use for everything else and mine on when i'm sleeping or otherwise not on the pc. no, i don't pay electricty and yes, i DO enjoy the extra heat.
this morning, while i was playing a game on xbox for no more then an hour, the PC was mining away. no errors, crashes, nothing like that. but when i came back from the xbox and went about my day (facebook, email, etc) i nitced text was different- pictures too. it's a bit hard to describe. everything looks flattened, and is heavily aliased. not just 3d stuff in games, i mean everything. text, icons, pictures on facebook or human faces. desktop backgrounds, everything. i think the anti-aliasing somehow got disabled system wide, but i've changed no settings that would cause that.
i've uninstalled and reinstalled both nvidia and amd drivers. i've run a system restore to before the issue. i've ran an update of direct x. i've triple checked every setting i can think of in windows and nvidia control panel. on perhaps 3 or 4 occasions over the last couple of weeks, i've had system hardlocks when stoping the ufaminer i'm using on the nvidia card. this was while using beta version of the latest driver and hasn't happened since i updated to the full driver release, but who knows it's relevance.
any ideas what the heck is going on, or how to fix it, short of replacing the card? could the mining have caused it somehow?
