FreeBSD 8.0 on a Dell Dimension 3000.
Problem: System freezes. I thought it was due to the heat here but it also happened at night.
I set acpi hint to disabled in loader.conf.
Results: New problem: fxp0 will stop working then system crashes. Requires hard reboot.

I've tried
Code: 
#watch dmesg
but I do not know how to properly use watch on FreeBSD.

I'd like to be able to see the exact message which occurs when the system crashes.

I used
Code: 
tail -f /var/log/dmesg.today
and the same for messages. Nothing.
System crapped out again. Interface fxp0 dies after an hour. System freezes on kde.
Solution will probably be to do a complete reinstall.

New question: Is there fan control or thermal?
 
Your Dell 3000 should have a Celeron D CPU (Pentium4 Family) and a Intel 865GV Chipset.

On a 865 chipset with a P4 with ACPI enabled i got
Code: 
sysctl hw.acpi.thermal.tz0.temperature
hw.acpi.thermal.tz0.temperature: 47.0C

I dont know exactly if your system have the same ability, lets take a look.

If you have
Code: 
cpufreq.ko_load=YES
in your /boot/loader.conf or in your kernel you can also see and control the frequency levels of the CPU.

Because of Pentium4 systems are always hot i would take a look on cpu cooler for dust and the mainboard (power cords off before) and try to find broken capacitors like this http://forum.gleitz.info/attachment.php?attachmentid=68838&d=1096558923

If they are not plain on the top, then they are broken. And if they are broken your system can become unstable in a unpredictable way.
