I have an older computer that was acting up and completely shutting down every 20 minutes, and now it rarely will start at all. I was wondering the best way to check to see if the power supply is burned out, or if there is another possible issue. I have a voltameter for testing electrical stuff, but want to make sure that I don't do something really dumb!! Thanks for the help!

hi, Tracker!

The best thing to do is to swap the power supply with a known good one, in my opinion.

However, here's how to test it:

Hey, Tracker,

Sorry to set you off half-cocked, but as you might have noticed that test is for ATX PSU only.

And you should take a look HERE first also.

Thanks again for the heads up...my multimeter confirms a 5 and 12 volt power supply, but I did notice a new POST beep sequence at boot up..1 long, 3 short (If memory serves that is an EGA issue...at least for IBM), but after another 15 or so seconds then I get another 2 short beeps...looks more likely to be a mother board problem and not a power problem. Thanks again! Tracker

To be certain, go to your BIOS manufacturer's web site and check out the beep codes.
