Random reboots - how to track down the cause?

Hi all-

In the past few days, my system has started randomly rebooting on a regular basis, perhaps once an hour. I'm sure it's based on some recent change to userland software, but I'm not seeing any smoking guns in /var/log/messages. What's a good triage process to figure who what the offender is?

Thanks,
Darren
 
If it was working reliably before, the question to ask is: "What changed?"

Hardware:
Did a partly-clogged fan finally go full dustbunny? Have power supply capacitors bulged and failed? Did RAM fail?

Software:
Did an application update introduce a problem? Did an operating system update cause a regression?
