Noticed this before my recent reformat and was wondering if anybody had ever heard of this issue. BF3 works fine, but if I launch The Witcher or Path of Exile, the games boot to a black screen with game sounds, and a blinking game cursor. I never had this issue with my GTX 570. I'm going to swap to my second 560 Ti 448 (haven't used them in SLI yet) and see if that fixes it, but this is becoming frustrating enough that I figured I'd reach out to you guys for any help you can provide. Edit: Same issue with the other card. Going to put in both for shits and giggles. Edit 2: BREAKTHROUGH! Windowed mode works, fullscreen has the aforementioned problems.
