If you have RAM installed, please remove it, reseat the the secondary 12v cable at the top of the board, this is often a problem site., test by shorting out the two pins for power on, (front panel header)
If still a fail. PSU needs to be shown, good/bad first by borrowing, swapping in a know good one, or, finding a local repair shot that will test the PSU, under load, (not possible without proper tester) some will do it free, or a small fee. Suggest you phone around. Last resort, buy a new one, but the MB could still be the culprit. Sorry could not be more positive.

Are you saying, you just burned out a fan? or did that happen at a previous time?

To test a PSU to see if it is not dead, I disconnect all lead to hardware, then connect one fan via the 12v 4 pin fan connector to a 12v 4 pin socket on the PSU, turn on the, because the PSU detects some load, the fan should start spinning.

No memory, no video card but the led power button lights up and then the green led appears again. CPU fan is spinning this time! But I don't know how to install the onboard speaker to hear the error beeps yet. I'm too exhausted to continue the puttering anymore today. I'll get back on track tomorrow and provide you a thumbs report. Much appreciation for all the assistance thus far.

I am not saying this did happen, but possible. If the PSU detects a short, or a short occurs, as when a fan goes kaput, one of the protection circuits is triggered, what resets the PSU, could be unplugging/plugging in, switching on off, with power/no power, don't know for sure.

That's a good sign, the orange LED will only light when RAM is detected. Can't find any mention of a system speaker on your board, looks like you have to see what is displayed on the Debug LED.
I would do your first test with one old stick of RAM in slot 1. Then the keyboard plugged into a top/back USB, or a PS/2 one. Try tapping F2 at boot, to load default setting.
Then the GPU/monitor, see if you can check out the BIOS.
then only the Boot drive, if you can boot to the desktop. add the mouse, power off, add the Optical drive,
Test the 1 stick of RAM that is installed, if OK, power off, add the second one into slot 3 and test again.
The storage/backup drive should be the last item added.
Good luck.
You are most welcome
