Windows 7: Random BSOD when laptop tries to sleep (ntoskrnl.exe)

Achro · 16 Nov 2012

I re installed my laptop a few weeks ago and installed all the HP Envy drivers recommended, when this problem started appearing. So I'm assuming it's driver related but I have no idea which.

I never get BSODs during normal use, but when I leave the laptop unattended and it goes into sleep mode, it might or might not BSOD with "DRIVER_POWER_STATE_FAILURE" or "DRIVER_IRQL_NOT_LESS_OR_EQUAL". It happens only like 20% of the time, seemingly at random.

Thanks in advance!
