Mark,
You can look through the output of the 'last' command. last may tell you
what the state of the system was before it rebooted/crashed and also the
time it happened. 'last -x' will tell you more detailed information
regarding system shutdowns and run level changes.
Example of a crash:
runlevel (to lvl 2) 2.6.32-24-server Wed Aug 18 10:10 - 15:44
(05:34)
reboot system boot 2.6.32-24-server Wed Aug 18 10:10 - 15:44
(05:34)
user1 pts/6 10.10.10.10 Wed Aug 18 09:37 - crash (00:33)
