The alarm means you have a hardware failure. Try opening the case to disconnect all CD DVD back of the units, also remove any add in cards you have as a modem, sound etc., disconnect all USB devices too. If it still does not start his memory, probably bad. If the CPU fan has failed that could cause too.
