Yeah they thought of that, but it's out of warranty by something like
three days. LOL ::groan::

Maybe re-inspect the mobo for bulging caps. Use a magnifying glass if
you can. Was there any power spike or a brown out? Can you see the
mobo make & model # ?
if so post back and we will go from there.-J

<----- Motherboard ----->

Front signal
Power ------------ Southbridge/SuperI/O -------------- PS_ON# ---> ATX
Switch ------------ as well as gate off logic PSU
ground for protection against mobo <---- +5VSB -----
problems

The power supply can refuse to listen to PS_ON# (if it has
an internal fault).

The motherboard may, for many different reasons, refuse to
deliver PS_ON#. For example, processor overheat gates off
PS_ON# (but you'd get a momentary operation before that
happened).

The front power switch could be bad.

The front power switch could be inserted onto the
wrong pins on the PANEL header.

The motherboard cannot turn on the PSU via PS_ON#,
unless +5VSB is operating properly. +5VSB should be
present, as long as the ON switch is in the ON position
on the back of the ATX supply. Using a multimeter
inserted into the exposed holes on the main power
connector, will allow you to verify +5VSB is present.
If the motherboard draws more than 3 amps from +5VSB,
the motherboard could cause the PSU to current limit
and disable +5VSB. So there is a little detective work
you can do.

Some links for ATX power connector pinouts, to help you
locate +5VSB. This covers three generations of supplies.

Paul, be rational. It wouldn't move that around by itself. The
working computer stopped working. It was a closed case. :)

Thanks for the links.

It's just a list of things to check.
