Hi, I have 2 gtx 285 2-way SLI. Both card OC'ed to 700/1300. Last night I was playing MW2, then suddenly screen went blank and nvidia error message popped up (can't remember exactly what the error was "bla bla... successfully recovered"). I just noticed my second card can't get to 700/1300. It's locked @400MHz. I've tried different drivers from 186 to 195.62 (I'm using this atm), but no luck there. I have to restart computer, then it works properly again, but after 1 hour of gaming the error shows up again. Is this hardware faulty or driver/registry issue? I thought it was MW2 maxed setting so I reduce the graphic setting and set both GPU to factory clock/shader/memory. Didn't work.
