Power supply not responding after install

geno368 · 08-22-2009, 04:00 PM

I am working on a pc running XP pro that has a bad PS. I took one out of another working pc with same voltage values and installed it. When I plug it in and turn it on, I get not response whatever. I put a multimeter on some of the molex connectors, and no power. The mother board looks ok(no bulges on Capacitors), but the system may have other problems since it has been down several months and I don't know any history. What should I look at next? Thanks in advance.

Follow the steps here using the voltmeter> Test your power supply with a multi meter

It seems after checking PS again that the MB fried it...Thanks for the help

Quite often a bad PSU will take out the motherboard when it goes.
