Hi all. I have a Gigabyte GA-B85M-DS3H motherboard which does not start. Pressing the power button turns on the power LED as well as the micro fans and power supply but there is neither sound in the speaker nor video in the monitor. At 4 or 5 seconds it restarts and does the same. I already tried changing microprocessor, memory, source, etc. If I disconnect the ram memory it starts to give intermittent beeps, signal that it is detecting that there is no ram in the Motherboard. Does anyone know what causes this failure? Thanks for the help.
