From a user perspective there is no such thing (nothing I have ever heard of). You could have a crack, cold joint, bad capacitor, bad IC, bad connection between part and board, and so on. Manufacturers replace boards and then rebuild them with extensive test gear.

Use a good power supply known to work elsewhere.
Use good RAM known to work elsewhere.
Use a good CPU known to work elsewhere.

If it won't boot from these components most likely it is dead.  Note that you may not usually have a CPU available for a range of motherboards and you will have to rely on the one in the present board.

Test with no other connections to the board apart from keyboard.  Remove all addin cards.  Make sure all hard disks, floppy disks, CDROM drives are disconnected.  Best to test out of case on a piece of cardboard.

That is your basic test.

Dead or faulty?

If dead then testing or repairing is not economically viable.

If faulty then a diagnostic test should find whether or not the motherboard is the cause of the PCs issues
.
Try UBCD hardware diagnostics.

I find that a POST card with voltage LEDs is indispensable when this issue crops up.  If you power up the motherboard and the voltage LEDS are correct, but the numeric display on the POST card stays at double zero (quad zero, for a POST 4 card), then it's time for a new motherboard.

PCI POST 4 cards are a few dollars on ebay.  A typical unit at $3

I have no idea whether a POST card works with a system configured for UEFI boot.

It would have been helpful if you told us the boards were faulty, not dead.
