Best way to confirm a dead board in any case is those POST diagnosis
cards.  They have a dual-digit LED output that changes depending on
the signal on the wire.  If at any time those dual-digit LEDs stay
permanently on anything OTHER THAN 00 is a failed POST.  If it fails
before it gets a shot at testing RAM or anything, there may be no beep

Always good to have one in a toolkit.
