I'm having a problem with my GTX 680. When gaming and sometimes watching VLC the screen will turn black (monitor turns off/on) or the game/movie will pause for a second and when it returns my card runs at half the speed/power % and my frames drop 50%. I have to restart to get back to my default clock.
I've tried setting both the GPU and MEM Clock Offsets to stock (have always kept Power Target at 132 so I'll try lowering that next) and my temperature never goes above 65%. This is a resent i7 build but it's also done this on my 955BE build as well. Could this be PCI Express 3? Please help.
