Asus z97-a
I5-4670k
Corsair RM850W Power Supply
ADATA XPG V1.0 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model AX3U1600W8G9-RB

It all started with
Event Viewer is "Level = Critical, Source = Kernel-Power, Event ID = 41
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

which I assume is related to
Event 55, Kernel processor power
Processor 1 in group 0 exposes the following power management capabilities:

Idle state type: ACPI Idle (C) States (1 state(s))

Performance state type: ACPI Performance (P) / Throttle (T) States
Nominal Frequency (MHz): 3401
Maximum performance percentage: 100
Minimum performance percentage: 23
Minimum throttle percentage: 23




I googled it. Tried a bunch of things. None worked. Fast forward.

I reset my bios
power comes on, fans whirl
Post failed
Cleared CMOS
Post failed
Removed all but 1 stick of memory
POST!

if I try to use dual channel i.e. slot 1+3 or 2+4
Post Failed

If I use 1+2 or 3+4
POST!

I have tried a bunch of things like
6 hours of memtest
re-seating the CPU

but I have finally hit a wall.

Please advise

EDIT1
I have also been monitoring voltages and they have been steady

While I still have the dual channel issue, the original still remains. cng.sys seems to be the culprit.

suggestions?

Any bent pins in the CPU socket?

Any bent pins in the CPU socket?

None.

All 4 memory sockets work individually or I can use 2 slots as long as they are not pairs.
