I have two boards with same problem,suzuki zw542 (platform:6-71-m74s0-d06a gp) switchs on and boots up and works(i can enter in bios and change options)then blinking 3 leds from right side (h.d.d-caps-scroll)with beep sound from speakers at the same time and then system turns off after about 1:37 minute.i think it has problem with bios.

system tested without h.d.d.
cpu changed.
ram changed.
any dumped bios please.
