Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.

Certainly seems like a hardware issue, but there's no easy answer to this one. It could be your power supply, motherboard, CPU, memory, even the video card. The power-button issue makes me lean towards power supply or motherboard though (assuming you've verified the power button works after a fresh boot).
If you have other parts on hand (even from another running system) you could swap components until you identify the culprit. If you find it's your power supply, make sure you replace it with a decent quality one, NOT one of those $25 units you find everywhere, or you'll have even more problems followed by a rapid failure in another year.
Well... The power button does work to boot the system back up. So...?
It's a small desktop computer Asus VivoMini VM65, not easy to swap parts.
Asus doesn't even have a picture of it anymore. Here's a bunch.
Then it could still be the power supply or motherboard. It takes a lot to override the hardware power switch and the power supply itself is usually one of the biggest culprits to random lockups. Beyond that I can't offer much, I don't know of any way to test the components unless you could afford thousands of dollars for specialized equipment. I've always had multiple machines available to swap parts so I don't have a different strategy for troubleshooting.
Thanks.
I thought there could be some place in logs the system could write error messages to. Even hardware derived.
I've been going through /var/log/* and found thousand of scary messages, but can't really make sense of any of those.
Something like a hard drive could generate recognizable errors in the logs, but once you get out into the motherboard or power supply, there's simply not enough monitoring available to detect problems. You might be able to record the voltage output from the power supply rails, depending on your hardware, but that still might not tell you anything.
