After you reboot the system, check the messages log (often found at
/var/log/messages) ... you are probably looking for a 'kernel panic'.
Kernel panics are usually caused by hardware failures.  In my experience
they are usually caused by memory or motherboard problems, although I've
had serious disk problems cause panics also.

I'm guessing that you run the Linux system with a GUI active ...
unfortunately, when the kernel panics it isn't always able to write the
last log entry out to disk before the system freezes up completely.
This is one of the primary reasons I never run a GUI on a server.  The
kernel panic information is always sent to the console, so if the
information isn't in the log file, I can always look at the screen.

If it indeed a kernel panic, and you can get the codes that are
reported, there is a tool available to parse the codes ... it's called
'parsemce'.  I've posted a copy of the source to
