Just for grins, pull off the cover and look at the electrolytic capacitors on
the motherboard.
Look for ones with the tops pushed up instead of being flat. This can cause
all sorts of odd behavior. Often the machine with a blown capacitor will
continue to run till it is powered off. Mostly I see this on Dell machines
but have seen it on other machines as well. They are pretty easy to unsolder
and replace. There are lots of pictures of failed electrolytic capacitors on
the web. You can get decent capacitors cheap on Amazon. I understand the
problem when the powers that be will not allow you to spend money. Now I work
in a lab and have nice soldering equipment available and can get away with a
lot more than a production environment. Maybe if your boss sees you taking a
soldering iron to the machine he will let you buy a new machine. :-)

The PSU's each have three LEDs: showing ac good, dc good, and no error.
There's a blinking green in the back, and that's it.
The pull-out panel shows nothing, and the two LCD codes show nothing, just
the cycle of figure-8's.
