If it is not using the swap (assuming some is configured) then you are
not running out of ram, so I don't think that is it.  If it is
overheating then that suggests a cooling problem.  Are all the fans
spinning smoothly?  Check whether any of the heatsinks are blocked
with dust.  A vacuum cleaner, used carefully, can be used to suck the
dust up.

Have you looked in syslog to see if there are any rude messages at the
point of crashing?
