Windows 8.1 Crashes Randomly

My computer has been crashing ramdomly lately with the error message WHEA_UNCORRECTABLE_ERROR. I thought this might be a temperature problem, but temps are fine. Thought it might have been my overclock so I disabled it, but it still crashes. I checked graphics card (780ti) and it's fine. so I swapped out the power supply thinking it would be issue. Still crashes. Unstalled windows because maybe it was a driver issue. Nope still crashes. Can anyone look into this for me? I've also included my dmp files and a specs list for my computer.

I know exactly what that is. I had this problem on an older desktop machine of mine that ran Windows Vista, but the blue screen would say "The system encountered an uncorrectable error". I swapped hard drives, RAM, even bought a new CPU and kept on having the same error. However, I did find the problem on my machine, but may not be the same as yours.

When I was in the BIOS I looked at the voltages on the motherboard. Some of them were correct, but then some were fluctuating very badly. Installed hwmonitor to check it in Windows, and confirmed that the 12V was fluctuating from 9V to as high as 13V when it should have stayed close to the 12V mark. It would blue screen when it hit over 13V or under 9V, which also caused my CPU fan to act weird. So I had some bad VRMs on the motherboard and it also caused a high pitched whine. The motherboard was out of warranty and got thrown away when I built a new system.

Do you have another system to test your video card, RAM, or HDD, or even your processor?

Looking at bad motherboard possibly at this point.
