canned diagnostic speaker rant: speaker making 101
The diagnostic speaker is the motherboards main diagnostic feedback device.
the motherboard may be telling you where the problem is.
my speakers have this plug

I use lamp wire but any stranded wire will do. literally any stranded wires. strip one end like so

attach the stripped end into the speaker spring clips on the speaker.
the other end of the wire should be trimmed like so the semi strip

by doing a semi strip the wire case is now the socket.
plug one wire to the first pin, and the second onto the fourth pin.
power on the system and listen for beeps
end canned rant

if you cannot coax a beep by removing the RAM and booting, the system will give a spcific code with no RAM, the motherboard is dead.

When you say boots up, do you mean that it actually gets to windows, but with no display?
If so, try booting in safe mode which requires no drivers, F8 during the boot process should get you there.
I use memtest86 as my first test.
It boots from a USB stick and does not require windows.

If you see this on two such motherboards, consider that something else might be at fault.

Perhaps the PSU or ram?
