Question My computer restarts literally random

[Deadlyxxx]

Hi I have the following problem. My computer restarts literally random, whether I'm playing or doing nothing, it restarts on its own. It is NOT a temperature because everything is literally normal and as I said, even while sitting on a desktop without doying anything it restarts. I changed the power supply with 1000W gold seasonnic and continues to do so. Any ideas? Could it be some kind of bios setting?
Sometimes it doesn't reboot for days and sometimes every 30 minutes.
MY PC SPEC
Ryzen5600x

I had similar problems around 6 months ago; my machine is 8 years old, so I replaced the PSU.

Well 5 days ago the problem started happening again, so yesterday I pulled my computer apart. I removed one of my cable extensions and haven't had a crash since. Things I'm certain it wasn't: dust, overheating, Windows updates, drivers, old/bad PSU, bad surge protector, brown-outs, etc.
