I just built the following and I am getting a POST 00 and CPU and RAM leds are blinking back and fourth.
I have rewired everything, reseated the PCU, reset CMOS a bunch. Took out all mem; took out graphics car; Nothing is working.
* Threadripper 3960X
* TRX40 AORUS MASTER
* NVIDIA GeForce RTX 2070
* TridentZ RGB Series 128GB (4 x 32GB) 3600
