I posted this on the other page. Generally anything I have done with drivers, etc has done nothing. But some of the changes that effect sleep/hibernate and power settings have increased stability.
I don't know anything about hardware, but yes something to do with the power and interrupts and having a dual GPU system. The 99% max processor state may work as well, but not sure if this applies to the BSOD often occurring after sleep, during youtube etc. problem.
Not sure if you tried the TDR TDRddidelay settings.
SOLUTION TWO: (Tdr & TdrDdiDelay).
SOLUTION THREE: (Link State Power Management).
SOLUTION FOUR: (NVIDIA Power Management Settings).
