Question PC continues to shut off unexpectedly

This is, from what I can tell, a different problem, so I will post it in a different thread here.
For context, this is my recent history.
https://forums.tomshardware.com/threads/pc-shuts-off-unexpectedly.3578909/

I took apart the PC in an attempt to try and fix the issue with the motherboard causing an electrical short as was suggested by Sohom.

No, I had not recently overclocked.

And for a time it seemed as if my issue was solved by removing the back plate entirely from the computer case.

Until these last few days when the computer has, once again, begun to shut itself down. Without being under load a significant load. There are no cable changes occurring, no vibrations occurring in the surrounding space, and things seem to be going fine, until the computer shuts itself down.

In an effort to try and cause a BSOD to tell some kind of information and rule out certain possibilities, I disabled the automatic restart that occurs, but the shutoffs are still occurring without displaying any sort of information.

I believe that either there is still a short somewhere, or there has been irreparable damage done to the power supply (be it because of the shorting or because of another type of failure within that part.

There did not seem to be anything wrong with the way the motherboard was mounted on the case, and now that there is no back plate on the case where the USBs are plugged in, there should not be a short there.

Another little tidbit of information that might lead to the conclusion of a power distribution failure is that VERY RARELY (twice in the last month) when I try and run certain games, the monitors will go black, as if they were no longer connected to the computer, and then they would come back on. Only once did the monitors not come back on, but while that was happening, the sound was still playing through my headphones.

What seems to be the cause of the problem and how do you recommend I approach solving it?

Now the problem related to overheat, hard ware and driver problem.

Because you said it is not heat problem in other thread, but did you check/monitor the cpu/GPU temps with some kind of software?
If you did. That means either the driver or hard ware has problem.
If no, check the temps with something like the MSI afterburner https://www.msi.com/page/afterburner

Or first to try: use the DDU to uninstall the gpu driver, then reinstall it. DDU https://www.guru3d.com/content_page/guru3d_driver_sweeper.html

And I think you just upgraded the PC, because you listed these parts( cpu, MB, RAM, case ) are new. If yes, I don't know you did reinstall the OS or not. If you didn't reinstall the OS, you may have the problem sometime, if the old one has the different chipsets.

Also try to use the " reliability monitor tool" you may find something, https://www.howtogeek.com/166911/reliability-monitor-is-the-best-windows-troubleshooting-tool-you-arent-using/
Or use the event log viewer https://www.howtogeek.com/123646/htg-explains-what-the-windows-event-viewer-is-and-how-you-can-use-it/

If you find something, post it.

And may try other GPU or PSU if you can.

I was monitoring the temperatures in the bios when shutdowns were occurring, for the CPU and the GPU (The computer once or twice shut off while I was staring at the temperatures in the bios). I will give afterburner a reinstall but I recently got into checking the reliability monitor tool, but it doesnt display any helpful information. When I look in the event viewer it doesnt have any recent hardware events at the shut off time, only the critical message when I reboot the pc saying that the shutoff that occurred at a given time was unexpected. Nothing is out of the ordinary there.

If at all possible I would like to save doing a reinstall of windows as a last resort.

The CPU, MB, and RAM were all new, but the case I have is not a new case, it is the same case that I have had for the past decade, so one idea is that the new MB is occasionally making contact with the case and that is causing the short. NOT SURE ABOUT THAT ONE.

I did not reinstall the OS, the HDD and SSD are still the same as before.

The GPU was upgraded months before this issue was occurring, this particular type of issue is exclusive to since I upgraded the MB, Processor, ram.

Using DDU to uninstall GPU drivers would work, but if the computer is just turning itself off without any sort of message being delivered to the event viewer or anywhere else wouldn't that not really be on the GPU?

If it were a software issue causing my crashes, wouldnt that cause a BSOD?

I will work on getting another power supply to test to see if it is a problem with damage to the power supply.
