What changed? If the rebooting started spontaneously, and not in a way
obviously related to your upgrading the OS or packages, then it is
Have you tried cleaning out and de-fluffing any air intakes or fans? A
common cause of rebooting like this is due to overheating. Making sure
the cooling airflow is unobstructed helps a lot.
You can try running diagnostic tools like memtest86 -- these will detect
many problems with RAM or CPU caches, which would confirm hardware as
the cause. If memtest86 doesn't find anything, that doesn't mean your
hardware is definitely OK -- there are ways that hardware can fail that
memtest86 can't detect.
