Another thing you could do is search for reliability history in Windows. It's just another way to see what events have happened or if any apps/drivers have crashed. It's not at all unusual to see entries in there, but you might get a clue and be able to track down the cause. When I had random Windows crashes on my Z390 machine it turned out to be a faulty USB cable - mind you, reliability history didn't help to find it, but it might help in your case.

I found the problem. The PSU seems to be broken. Things got worse, computer was powering on and off in seconds, I exchanged the PSU. Up to now everything seems to work.
