I just fixed a test box that kept getting something like "received INT 11 - no one cared" and then locks up. Replaced two caps - I yanked them from some old, defunct power supplies.
How did you know they were bad? Could you explain to her
what to look for
and how to use a Multimeter?
You look at them - no meter required. The tops of the electrolytic capacitors should be flat and clean looking - not bulged, puffed or discolored. It's all described very well in the wiki page.
Replacing the capacitors does require soldering equipment and soldering skills. Or just replace the whole MB or power supply - whichever is the problem.
I've lost track of who told me to check capacitors, so apologies to the person concerned. I did look - and everything looks fine.
