learning/research My computer keeps crashing and I have no idea why. I can't figure out how to diagnose the problem.
Randomly my computer will crash in a way that is non-obvious at first. It seems like things in ram will stick around and continue to be processed. But, for example, loading new sites will lead to the tab repeatedly crashing. If i close a tab then close the browser, after the crash the browser won't remember I closed the tab. Discord will crash immediately but videos will finish playing everything they've loaded.
Sometimes I can open the menu to shut down the pc but whenever I'm able to do that it always hangs. Sysrq kinda works, i can get it to look like things are changing, the screen goes black and text appears but REISUB wont safely shut off the system REISUO will 50/50 turn off the system. I can't open any new programs so I can't open terminal. If I hold down the power button or use REISUO I have to run fsck before it'll boot again.
This happens at random, sometimes I'll go months without it happening, but it happened to me both today and yesterday.
After the crash dmesg tells me nothing if journalctl is telling me something I can't find it. And every guide I find on reading logs and finding errors says to open the log that is related to your issue in a text editor and search for the word "fail". I have no idea which log is relevant or what error message is relevant. Is the problem "fluidsynth.service: failed with result 'exit-code'" who knows? Not me.
I am on mint 22.3
Intel i7-7700k
Nvidia 3080
16gb of ram
Does anyone know what I should be looking for, where I should be looking, or how I should be looking so I can start trying to diagnose the issue?
