Have my build first:
CPU: AMD Ryzen Threadripper 1950x
Motherboard: ASUS ROG STRIX X399-E Gaming (BIOS version 1002)
GPU: Gigabyte GeForce RTX 2070
RAM: Corsair Vengeance LPX 32GB (2x16GB)
SSD: Samsung 860 EVO 2.5 inch
PSU: Seasonic Prime 650 Titanium
So I've done what I think is right, installed everything, and connected all the cables. I hook the HDMI from the monitor into the computer, and power everything on. The motherboard starts POSTing (the 4 little LEDs), but either ends up with a white LED and gets stuck on either Q-Code 0d or 68. Monitor stays black, no boot, no BIOS, nothing.
I've checked my RAM to make sure it's on the QVL list for the motherboard.
All fans are running.
Thanks in advance.
