Hi all,

Having some issues with a new build.
As the title mentions, I am receiving the q-code A0, which I have read means "just fine". However, the Q-LED remains yellow (BOOT error) and my GPU projects nothing to my scree, I have tried every possible output slot on the GPU and PICe slot on the mobo.

Motherboard: ASUS x399 Zenith Extreme
CPU: AMD Threadripper 1900
CPU Cooler: Noctua U14S
GPU: Auros 1080ti
RAM: GSkills V 1 stick 16GB
Storage: 860 evo 500GB (x1), 3TB Toshiba HDD (x3)
PSU: Seasonic 1000W Titanium+
 
Solution
Have you updated your motherboard to the latest drivers and BIOS?

ROG ZENITH EXTREME - BIOS Version 0305 - 2017/08/04
1. Fix System hang when using both DIMM.2 and VGA Card
3. Revised some VGA may hang 0xAF0E when CSM disabled.

Try reseating your psu to motherboard plug, also try backing off a few turns of the screws on your cooler plate to the cpu and reboot see if that helps. I had same problem when I ADDED A COOLER AND CRANKED IT DOWN TOO HARD.
