System hangs/crashes/sometimes reboots

Yesterday after the memory test I simply rebooted it and left it at the XFCE login screen. Turned monitor off, came back this morning, and I can’t even get the monitor to output (keyboard not waking it up). I had to hold power button down.

This isn’t a Laptop right? So you have a Num LED on your Keyboard and still can be turned on/off correct?

When Num/Capslock/Scroll LED not flashing and can be manual turned on/off, that is a good sign.

Probably switching Kernels 6.1 LTS or the newest 6.10/6.11 Kernels to evade issues.

With activated Swap, you can also look in your logs after a reboot.

journalctl -p err -b -1

Reisub, could also help to revive your system:

[HowTo] reboot / turn off your frozen computer: REISUB/REISUO

Difficulty: ★★☆☆☆ This tutorial was created because people are using a hard power off during freezes, so this will teach you how to turn off your computer when everything is frozen using softer means. So whenever you see someone saying they had to “Power Off” or “Hard Reset” their system without doing a REISUB, please send them here! If you’re reading this in response to a question, please click the green link above this text to bring you to the full unabridged text of the tutorial…

Another ways to rive your system by pressing:
crlt+alt+backspace
crlt+alt+F1-F5 Keys switching to TTY and back to desktop.
