   OK, that is not typical behavior so lets delve deeper. 

Remove all connections from the board, including front panel header. Connect only the 24 pin power and CPU/CPU cooler and then short the power on pins with a screw driver or other conductive metal object. Also make sure the clear CMOS button on the IO panel of the board isn't stuck or depressed by the IO shield. 

Let us know if you get any display on the debug LED display.

	I couldn't get my new build to do anything, other than one fan (out of 6) to spin up at full rpms; no post, no Dr Debug led. So went back to basics breadboarding, here's the quick lowdown so far.. Case = Raijintek Thetis Fans = Noctua U12A + 4 case fans PSU = Seasonic SGX 650 M/B = ASRock Taichi X470 RAM = Corsair Vengeance lpx (3200) CPU = Ryzen 5 3600 GPU = RX 570 Sapphire OC So bare bones Taichi with: one stick of RAM in A1 slot, CPU cooler (U12A) plugged into CPU FAN1 - System Panel headers hooked up to power button / led, etc - alarm beeper plugged in. ATX power connector and 8 pin 12V power connector firmly plugged into mobo brings about: U12A fans fire up properly for 15 seconds - power down - then power back up for another 15 seconds, rinse / repeat. (I replaced the BIOS battery with new which actually kick-started the U12A fans to work). NO Dr Debug led, no beeps, no beep code sounds, nada. Before I waste any more time guessing, if Dr Debug led is dead, is the motherboard faulty? RMA time? Thanks.
