Others mentioned that it sounds hardware related. That reminded me that you should visually inspect all ports, especially unused ones. I had a system locking up constantly once and it turned out to be from debris in a usb port on one of the monitors was causing a short. It’s something that wont necessarily cause logged errors and can cause seemingly random behaviour that will have one chasing problems that don’t exist. USB ports and DVI plugs especially can be hard to notice with how they are constructed. Audio jack holes too. Make sure there’s no breaks in any cords. It seems too simple to be true and then it happens and you feel foolish for not having thought of it.

I remapped the capslock key to be third level shift ³ or fourth level ¼ if used with normal shift and in the unlikely scenario where I need capslock, I hit both shifts at the same time to toggle it.
Now I can do all sorts of neat symbols! ∞÷⍉±0≠¡⍶⍹⍷§⌾M€⍥
