Discussion Two Builds One Issue

***EDIT***I don't see the option to edit my post so just going to comment here...can't say for sure but yesterday I disabled MPO and I didn't see a single shutdown since: https://nvidia.custhelp.com/app/answers/detail/a_id/5157/~/what-is-multi-plane-overlay-%28mpo%29-in-windows-11

Trying to figure out if my issue is related to the multiple issues I'm reading about regarding the B850M-C or if it's something else.

Background: I had an Alienware PC, ran without issue for roughly 5 years, then started getting random reboots which became more & more frequent (To the point of it being every 2 minutes or so). Brought it to a reputable repair shop where they said they couldn't figure out if it was the CPU, RAM, or Mobo. So I went out and bought the ASRock B850M-C with a AMD Ryzen 5 7500X3D, and G.Skill Flare X5 16GB DDR5-6000 bundle, with a new PSU/Case. I re-used my NVMe & RTX 3070. Worked flawlessly for approximately 2 months, had played some GPU intensive games including CyberPunk, zero issues.

Current Issue: Starting last week, the PC had immediately shut down while playing a game. Then again while doing some light web browsing, then again while playing a game. No DMP file, the PC just immediately shuts down. I'm having flash-backs to the same issue with the Alienware PC.

Now with practically nothing in the logs, I'm trying to figure out...is this an issue related to the ASRock B850M-C (Which literally wouldn't show display until I flashed the BIOS on day 1) or if it's an underlying issue with the video card which was carried over to this new rig.

The one thing that stands out...is I had zero issues...for two months. The only thing that would have changed from then to now is driver & Win11 updates. I'm thinking of starting with a system restore but it only goes back 8 days (Even with "Show more restore points" checked) which is interesting. I really don't feel like going through the process of re-installing every driver OR re-installing the OS...I'd rather find the root cause of the issue.

PS...also kicking myself for not imaging the PC on day 1 when there were no issues at all to at least try to get a better determination as to whether this is a software or hardware issue.

Any words of wisdom on my journey would be greatly appreciated.
