re: BSOD DRIVER_POWER_STATE_FAILURE Windows 8.1 x64
Within the very first Dump 052815-5484-01.dmp, a small one i discovered

Sounds OK

While CPU is identifyed as

what matches OP's Discription
the later revealed Chipset Bluerobot stumbled upon & myself got the same result:
> !DevNode ffffe001a9402d30 :
> DeviceInst is "PCI\VEN_8086&DEV_0C01&SUBSYS_186D1043&REV_06\3&11583659&1&08"
which decodes to an
Intel Xenon(R) CPU E3-1200 v3/4th Gen Core CPU PCI Express Controller x16 = 0C01
i would likely declare that Mainboard / CPU as the failure, unusual a cpu changes it's ID in that way?
Other possibility is memory, so a memtest might clear up that myteriousity, if not L2 itself is the Problem?
Just an Idea from my findings.
