Neither the bios or any software voltage monitoring are any good in diagnosing PSU problems as neither reads voltage continiously. For the same reason most digital voltmeters are no good. What can happen (I have had it twice) is the PSU voltages can spike down very quickly and cause the system untold problems. Such a spike will NOT be picked up by most voltmeters. I have successfully used analog meters to check this though (An AVO). All voltages need to be checked including the 12 Volt line. In both my cases the system lockups were caused by the 12V line droping low (11.2 volts) for only around half a second, causing the hardisks to shutdown. This caused an unrecoverable error from the kernel. The symptoms in my case was an almost complete hardlock up but with the mouse pointer still working.
