Windows 10: Random lock screens

Not a bsod, but my W10 intermittently locks (not log off) my screen during use. I would be doing anything from nothing to actively playing a game and the computer would lock the computer. This has been a problem for a while, and while it was more frequent in the past year, it has slowed down quite a bit but is still happening. How can I diagnose this problem and pinpoint the exact cause? I've checked the event viewer but I didn't find anything useful, or did not see anything that I found to be suspicious. I have reinstalled a new OS a few months ago when I was upgrading my SSD, but the problem still persists. Any searches related to the topic has copy-pasted generic answers by some "Windows Advisor" which do not actually help in figuring out what the problem is. - Always up to date windows - No problems with hardware - No virus, etc etc etc
