I think its 100% certain that it is hardware, or software. <*GRIN*>
You can try randomly replacing things, which can be expensive, time-
consuming, and not necessarily effective -- how do you *KNOW* that the
parts you're putting _IN_ do not, themselves, have (as-yet undiscovered)
I'd try to make the box tell me "something" about *why* it crashed.
crank up the level of logging for 'kernel' events in syslog.con,
enable crash dumps, and make sure the boot process saves the dump
Then you can get into the weird,wonderful, world of 'crash dump'
With a few dumps in hand, you can begin to see if there is any consistency
in what the machine was doing -when- it crashed.
