Quick question: Are you using the NVidia driver 320.18? From your dxdiag file it seems so. There are several reports that that driver causes massive problems. You might want to downgrade to the previous version, until they have sorted out those problems. Even if that means not being able to fully utilize your GTX 780.

I am using 320.18 because it's currently the only WHQL that actually supports the 780s -- To go backwards to 314, the cards aren't yet written into the INF so, I'd have to modify the INF there-by losing the WHQL which, would cause me more general issues then solutions.

I will upload those files later this afternoon -- Thanks.
