Yes. It's always turned out to be flaky hardware for me.

Look through /var/log/messages.

Well, you really can't "solve" it, so much as troubleshoot it. Make up
a list of possible causes, and then start checking each possible
cause. You haven't given any real information about the system or the
problem, so we can't eliminate anything. My top suspects would be the
PSU (old or inadequate) and CPU (overheating or overclocked). Memory
and the I/O subsystem would be next, but they tend to cause
random process failure rather than system shutdowns when they go
flaky, so I'd try them last.
