A voltage limit threshold has been exceeded

[MrBaseball]

Im getting this error on a Intel SR2200 2U Rack-Mount Server:

A voltage limit threshold has been exceeded. Press <F1> to override boot suppression, press <F2> to run setup.

The only info I have found on the error is in a PDF from here: http://www.alliancesystems.com/documents/ssh4_tps.pdf

13.5.4 Boot Inhibit
After all POST tasks have finished but before booting the operating system, the BIOS checks the system temperature and voltage. If the temperature exceeds a limit value and / or if the system has an abnormal voltage, POST will display the message ?Press <F1> to override boot suppression, <F2> to enter Setup?. The BIOS will continue to poll the temperature sensor. If the sensor returns to the acceptable range, the POST process will automatically continue and will allow the operating system to boot. If the user presses <F2>, the system will enter SETUP. If user presses <F1>, the system will continue to boot.

What could be causing the error? I thought maybe there were some bulging caps on the mb, but I couldn't find any that looked bad. Any ideas?

My guess would be that some voltages are too far out of spec. Does the board do monitoring? If so, check it to see if anything doesn't look right. Also, use a multimeter to check voltages coming from the power supply.
