Welcome.
I have exactly the same problem with the same error. For me, the error occurs once in about 2 weeks.
DRIVER_POWER_STATE_FAILURE (9f) A driver has failed to complete a power IRP within a specific time (usually 10 minutes). Arguments: Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time Arg2: fffffa800aa62a10, Physical Device Object of the stack Arg3: fffff800044073d8, nt!TRIAGE_9F_POWER on Win7, otherwise the Functional Device Object of the stack Arg4: fffffa80127a3600, The blocked IRP
The solution to the BSOD does not occur is to disable Nvidia graphics card in Windows.
I wonder if this error is not related to the fact that you and I have Windows 7 and the computer is installed as standard Windows 8.
Maybe there is some incompatibility with Windows 7?
Sorry for my English.
