WTF voltage error check bios for details

[The PIT]

This has just started occuring on my P4S533 or may have been occuring for some time. Can't see the bios screen normally. Go into the bios as instructed all voltages are okay no errors.
I don't trust software to give me the proper details so either I ignore it or pop out and buy a bigger power supply. Unless I can get hold of a power supply tester cheaply.

did you try setting BIOS settings back to factory defaults?

either it's failing or you've got a bug in the BIOS (updated it lately?)

A bios update fixed this issue for me, on an Asus P3B.

Found it and just saw a brief flash of red. It was the cpu fan just being a little slow getting to the speed limits. Something I'll have to keep an eye on though.
