As title suggests.
Coming home the other day I find my PC started to restart out of nowhere, with no warning before or errors afterwards. I haven't changed anything and haven't had this problem before.

Any suggestions on what to do?

Check the thermal paste for the CPU. Could need to be reapplied and has gotten old.

Quite possible - had this happen on a 2019 Dell (so it has some runtime on it).

Re-did the paste and now it's stable.

OP should also check the system log to see of it's recording the shutdowns, or of anything happens before them.

Could be update restarts (which is why I run an LTS version), and you may see nothing at all in the log which could point toward overheating.
