My FreeBSD 7.1-RELEASE-p3 system has gone down a few times in the last
two days. I'm trying to figure out why, but there is nothing in
/var/log/messages or dmesg about the incident.

Here's the output from the `last` command:

As you can see, the system reboot several times, and crashed the most
recent time. Only one of the shutdown/reboots listed is valid - the
furthest one.
I have no idea why it is rebooting/crashing. It has been completely
stable until about 1-2 days ago. If anyone can direct me to post the
output to any commands or any log messages, I'd be more than willing
to do so in order to help anyone diagnose my problem.

Thank you for your time.

What you are experiencing are the early warning signs of disk drive failure or over heating problems.

Before doing any thing else make backup of your user data if you have not done so already.

Then open your box and use a small brush and a can of compressed air to blow the dust off the motherboard and the fans. Give special attention to the fan in the power supply. If PC is older than 3 years or has over 1 year of continues use then replace the power supply.

IF problem still happens replace hard drive.
