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. http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.
