Hey everyone,
I'm running into a frustrating issue and could use some guidance on how to pinpoint the faulty component.
My system completely locks up every few hours. It's not just a DE crash; the entire machine becomes unresponsive. The mouse and keyboard are completely dead (no cursor movement, Caps Lock key doesn't toggle). I've tried waiting 10-15 minutes to see if it recovers, but it never does.
REISUB does not work. Holding Alt + SysRq and pressing the keys in order does nothing. The only way out is a hard reset using the case button.
The last time this happened, I ended up buying components for a new computer and replaced them one by one until I found the faulty one. I'd rather try a more targeted approach this time. Though if it takes too much effort, I do have another computer I can fall back on.
Any advice on how to diagnose this efficiently? Logs to check, stress tests to run, or hardware to suspect first?
Thanks in advance!
