I would disable Windows auto driver download from windows update just to be on the safe side.. Makes no sense but neither does the rest of your problem from what i been able to read so fare.
Thanks, I'll do this as well.
Just never had this sort of issue with drivers before.
GPUZ records it fine. I've ran furmark etc and they all record it fine as well. Just seems to be hardware monitor, dxdiag and sleeping dogs. Very frustrating.
