ok weird one okay, this is driving me nuts... black screen, fans ramp up, and about five seconds later Windows comes back like notihng happened, then this pops up:

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
Its always while waking teh monitor from standby. My home-built tower is not overclocked and temps look normal in the vendor overlay. The only change i can point to is the GeForce Graphics Driver update from NVIDIA. Ive already restarted a dozen times, obviously. Is there a log somewhere that tells me what actually timed out, or am i stuck guessing?
