Question PC Keeps restarting randomly.

[Tired_One]

About 6 months ago my PC started restarting overnight or during the day when I was not using it. I had Windows 10 installed at this time. It will either restart, or it will just freeze with the display still showing the desktop just frozen. I figured I would upgrade to Windows 11 and see if that fixed the issue. I did not fix the issue. I have tried looking into event viewer to find what is the cause but I have not been able figure it out. Any help would be appreciated.

Motherboard - ASUSTeK COMPUTER INC. TUF GAMING B550-PLUS

Processor - AMD Ryzen 7 5800X 8-Core Processor, 3801 Mhz, 8 Core(s), 16 Logical Processor(s)

GPU - NVIDIA GeForce RTX 3060

RAM - PVB432G320C6K x2 DDR4 16GB 3200 MHz CL 16 1.35v

Disk Drive - Samsung SSD 970 EVO Plus 1TB and Samsung SSD 840 EVO 500GB

I have replaced the battery on the motherboard. I have tried a different power supply. I have reinstalled Windows 11 from scratch.

I am not sure how to find logs or other ways of diagnosing the problem other than event viewer.

Any help would be appreciated.

The problem remained after replacing the power supply?

Yes it still restarts after replacing power supply. The original power supply was a EVGA 500 W3 and I swapped it for a Thermaltake Smart 750W 80 plus I have on another system.
