Machine shutdown unexpectedly unexpectedly

Hi One of our Linux box got shutdown unexpectedly .
I have noticed that 4 out of 8 nic ports were not blinking .

I m not sure where to search logs .
Any help would be appreciated.

Please find the var/log/message

Feb 24 15:05:05 XXX kernel: vlan225: port 36(tap173.0) entering learning state
Feb 24 15:05:05 XXX kernel: device vif173.0 entered promiscuous mode
Feb 24 15:05:05 XXX kernel: type=1700 audit(1298540105.890:655): dev=vif173.0 prom=256 old_prom=0 auid=4294967295 ses
Feb 24 15:05:05 XXX kernel: vlan1021: port 37(vif173.0) entering learning state
Feb 24 15:05:20 XXX kernel: vlan1021: topology change detected, propagating

Feb 24 15:05:20 XXX kernel: vlan1021: port 37(vif173.0) entering forwarding state

********Machine was shutdown at this time(However 4 out of 8 nic port were not blinking so i started it manually **********
Feb 25 08:52:56 XXX syslogd 1.4.1: restart.
Feb 25 08:52:56 XXX kernel: klogd 1.4.1, log source = /proc/kmsg started.
Is it a case of power failure as nothing specific is getting logged(Just a wild guess).

Is this a machine that is not long in use? In that case try some software that give a lot of CPU load. In the past
CPUs caused this when they got too hot, because of bad cooling (like for instance too much thermal paste between cpu and heatsink)

some bioses can log info that can be accessed via the bios menu when starting (via keys like F2 DEL or F10)
