X99 PC Issue. Cast your bets.

[Archaea]

interesting thing happened this weekend to my main rig.

Works normally. I power it down normally like always. Later that day I go to power it up and the fans all come on 100%, (case fans, AIO CPU radiator Pump, and graphics card) but the motherboard is completely dark (No RGB lighting at all) and I get no signal to my monitor.

I figure my RAM probably died. I pull all four sticks and hook up the little 4 pin motherboard speaker so I can listen for beep codes. I turn it back on sans RAM and it does the exact same fan and light thing, but no beep codes from the little speaker. The motherboard is still completely dark.

Another curiosity is that it won’t turn off. I push the power button on the front of the case and it just resets for a brief second and then fires back up again. No beeps. Fans at 100% and loud.

My guess is bad motherboard now.

What’s your guess?
