[SOLVED] Question: Windows 10 - Likely culprit of BSOD - NMI Hardware Failure?

[Jason3022]

Windows 10/64-bit
Motherboard: Gigabyte P55A-UD4P
CPU: i7-860 @ 3.8 ghz
16gb ram
GPU: EVGA GTX 970 (latest Nvidia driver, running @ stock clocks, no aftermarket software)
Dell 25" 2560x1440

1 week ago, I started getting BSOD - NMI Hardware Failures, while playing games.
I have not made any hardware changes.
I figured it might be a Nvidia driver, so I downloaded the latest one.
The BSOD continue, while playing games - 3 different games so far.

I have never analyzed a memory dump before, so I have set up the system to create a Full memory dump - is that what I want to create? The default appeared to be a Kernel memory dump.

I have also downloaded the WinDbg Preview - to analyze the minidump the next time it happens. Hopefully I know what I'm looking for, otherwise is there some folks here that are good at analyzing these things?
-----------------------------------------
Edit: Just ran the Windows Memory Diagnostic app - no errors found.

I need help guys.

Today my computer just turned off and wouldn't turn back on.
I removed the psu from the computer, used a guide online, on how to check psu for power using a paperclip. The psu fan powered on no problem.

I then checked all the pins with a multimeter.
The 3.3v and 5v are fine. The 12v rails are reading about 11.8v
Could that be low enough to cause the computer not to turn on?

When I clicked the power button on computer,there would be a brief red light power on indicator, then nothing.

Or is there a chance my motherboard is not working?

I am clearly forced into buying something new, whether it's a psu or entirely new computer I'm not sure.

looking at this - https://www.lifewire.com/power-supply-voltage-tolerances-2624583 - 11.8 should be enough.

it could still be PSU, it is 7 years old. If my PC didn't turn on, it would be first place I would look

If it was me, I would take it to a repair store as they would have a spare PSU they can throw in PC to test if it is the cause, save buying parts without being sure they are cause.

It turns out the GPU was dead.

I bought both a new PSU and GPU (inexpensive one) to test.
Test 1: The new PSU made no difference, the old GPU still didn't come to life.
Test 2: The new GPU with the old PSU instantly worked.

I will be returning the new PSU for a refund. No problem, no restock fees.

I will be hunting for parts in the next few months for a new build. Perhaps Black Friday etc.
It no longer makes sense to put too much money into this old build. But will keep it for a back up computer I suppose.

Now I will know that in the future, if your monitor just turns off, while the game audio is still playing, ctrl-alt-del does not bring up task manager etc., then I'll know the GPU is likely the problem. I just didn't associate or think about that connection at the time. I merely turned off the computer and turned it back on.

It was an Evga Gtx 970 ftw - 4.5 years of life.
