is my power supply failing?

[Matt Price]

Hi folks,

I've been having some trouble with hard freezes/crashes and installed
the lm-sensors package on my debian sid box.  It gives readings that
sound   somewhat scary, e.g.:

my question:  how do I find out more about what are acceptable voltage
levels on Power Supply outputs? for instance I'm getting a +12 voltage
of about 13.0 (not in this particular case, I knw):  is this way out
of spec?  If so, will changing my PS fix thep roblem?

thanks a lot for your help,

matt
