Question PC shutting down even when idle

[KomiseBebis]

I've had this motherboard for exactly 3 years. Before that I used a Ryzen 5600X and after a year and a half I switched to the 5950X. On the recommendation of a friend and because the metrics showed that it was always operating at boost and consuming a lot, I undervolted it and locked the clock at 4.6ghz and when I did any cinebench test or similar that stressed the processor the motherboard would shut down and restart since then I did my best to keep it from being under high stress for too long.

After a few minutes out of the socket it came back as if nothing had happened, with no BSOD log. The temperatures of the VRMs were also normal, they didn't even get close to 105 degrees Celsius which I found by researching that it would be the temperature to end up damaging one of them but it is the only thing that fits so that the whole set does not work, the malfunction of the VRMs

My Specs:

Ryzen 9 5950x
Asus ROG Strix B550-F
Crucial Ballistix 4x16 3200 mhz
Asus TUF RTX 3070
Corsair RM750

It's pretty much what happens in the video by user "The Nubing": it just switches off and then switches back on after a few moments.

Have you tried going into bios and resetting it to normal/original settings? Changing voltage and locking in a certain cpu speed can cause these problems. I do not see any advantage to doing this with the upgraded cpu. Computer usage should be worry free.

Yes, I reset the BIOS, updated to the latest version, used 2 stock processors (Ryzen 2600, 5600X) and it kept shutting down after a few minutes even when idle

I would use a program like HWmonitor https://www.cpuid.com/softwares/hwmonitor.html to check voltages, and cpu/gpu temps for the few minutes that it stays working. See if you can track down an anomaly with your psu, temps with all your hardware and motherboard info.
