A kernel panic or OOPS comes to mind first. That's very broad class of the problem, to say the least, hence the need of kernel logs. Xorg hang is the second possible option. AMD hardware is somewhat problematic here. Barring above - an overheat is the third possible scenario here.
Memory errors under load can also cause kernel panics. I like to test RAM by running multiple concurrent memtester processes to simulate multithreaded load.
Some AMD platforms had a reputation for instability with anything less than the highest performance RAM.
mprime (Prime95) is useful for stress testing a CPU. Kind regards, -- Ben Caradoc-Davies <ben@transient.nz> Director Transient Software Limited <https://transient.nz/> New Zealand
