because the A51 Motherboard ! poor Quality, missing Features and Barebone BIOS Settings make it the worst X99 Motherboard ever. it's true, it must be Alien Technology because this poor Quality is out of this World.
we get similar Threads pretty often here. sometimes it helps to unplug all Cables, remove the Coin Cell Battery on the Motherboard and then hold Power On Button for a Minute. but most of the Time you need a Motherboard Replacement. if you still have Warranty then call Dell Support and if not.... well.... 500 - 600$ for a new Board, depends on where you live.
