[PLUG] Unexpected machine reboot

[King Beowulf]

Take a look at
/var/log/messages
/var/log/syslog

the reboot could be (1) thermal (overheating) (2) hardware issue: cpu,
mobo, add on card...

At this pt, I'd check over heating since you had a lot of stuff
running. You can check cpu and mobo temps etc with any number of
utilities. You can use BOINC (seti at home etc) as a stress test.

Is the CPU heatsink loose? When was the last time you reseated it with
fresh thermal paste?

Good luck.
