I have a DQ77KB which up until a case swap was working properly. On connection to power all I get is a single quick flash of ME_STATE and Standby Power LED and then nothing. The fan does start, no beeps or anything. I've tried to clear the CMOS but this hasnt made any difference. I've removed all memory, MSATA etc so its just the motherboard and processor connected but it's still doing the same. Can anyone advise how to diagnose the error?
Thanks for joining the Desktop Board community.
Sorry to hear that your motherboard is not posting at all.
Did you test removing the RAM? did you get any beep tone?
