Problem is, my PC which had worked happily for many years suddenly switched off as soon as it was switched on. Fans spun momentarily, then nothing. First response was to replace the PSU. Now when I switch on it stays on, fans run, HD light comes on but does not flicker as it would if it was working. Apart from that nothing happens, no signal is reaching the Monitor. Changing the HD makes no difference.

Really all I am seeking is confirmation from an independent party that my diagnosis that my M/B CPU combination has at last had its chips is correct. Right?

Check all all connections to motherboard (you may have missed one) especially the 4 pin next to cpu if you have an Intel cpu.

No, I have a Duron 850 and the board is a A10LMR made by Eagletec although I believe it was some sort of generic board made by several manufacturers. It's ever so old.

With the machine switched off

Take out the power and IDE cables from the hard drive and any cdrom drives you have.

Just leave one stick of ram in the computer, if you have more.

Take out any PCI cards, white slots.

If you use a graphics card and the computer has onboard graphics. Take out the card and plug the monitor cable into the onboard graphics.

Unplug all connections on the rear of the machine. i.e. keyboard mouse and usb.

start up and see if the computer POST's. i.e. first page.

Also take out

Power for the floppy drive, if you have one.

Dick, thanks very much. I did as you said and got the Post screen. I then refitted everything one at a time, switching on and off each time and the problem turned out to be an Ethernet card. All OK now, money saved and so much for my diagnostic abilities! Thanks again.
