Re: Troubleshooing advice, please...

The computer was dead and lifeless as a doornail. I correctly guessed 
that the power supply had died, and I bought and installed a 
replacement. What I didn't anticipate was that the REPLACEMENT PS was 
also defective and I ran around in circles for a few days thinking the 
motherboard was bad, instead or also. I finally installed a second 
replacement PSU and I'm back in the saddle. Unfortunately, the dying 
PSU killed one of my hard disk drives and it will take me a while to 
recover from that.

Frustrating, yes. It has probably happened, but I don't recall a PS 
just winking out like that. Usually they get flaky and let me know they 
are on their way out. I used to work in a computer lab where we had 
lots of spare parts to test things, but now, at home, it's a lot of 
guesswork and blind buying of parts.
