[Gllug] Power supply problems

[Roger Whittaker]

We have a machine which has two hot-swappable power supplies which slide 
in.  It has started crashing - the BIOS contains a "Power management 
setup" section, and at boot time there's a warning from the BIOS that 
there's a power error.  Looking at the power management stuff in the BIOS 
shows that the +5V line is at 4.5V or lower - it reports an error if it 
goes below 4.6V.

My questions are 

 - what might have caused this to start happening?  Is there anything that
   might be casuing a drain on the +5V in particular?

 - is it a good idea to try new power supplies?

 - any other clues ...
