Display errors, but only during BIOS

[NaClKnight]

Building a PC from spare parts. The PC's BIOS menu is basically unusable due to constant artifacting and black screens. The MB reports a GPU error via the VGA light on the MB
When I boot into Windows 10 there are no errors. No black screens or artifacts at all. Running GPU stress tests in OCCT has not reproduced the issue either. Only during startup/BIOS

BIOS is updated to the latest version, and this issue occurred before and after the BIOS update

Build https://pcpartpicker.com/user/NaClKnight/saved/M6YHWZ
CPU: Ryzen 2600
MB: Gigabyte B450 Aorus Elite
GPU: AMD R9 Fury X
PSU: EVGA BQ 700

This PC ran smoothly for months until yesterday, and I have not installed or removed any components recently.
Furthermore, HWInfo reports that the GPU and VRAM are both idling at 30C after booting. 
My only inkling that something is wrong with the GPU came during a stress test where the VRAM reported temps 20C higher than the GPU core after only 3 minutes.
 

I've never disassembled this GPU but maybe it's time to do so, and reapply thermal paste/pads?

this is a good start. added benefit is you will reseat the GPU in the process so 2 birds 1 stone.

 

Keep in mind that standard stress tests normally only stress the 3D engine and related components with drivers loaded, where in BIOS you'll be running the 2D engine and basic VGA drivers.

Reseating the GPU appears to have solved the problem. Have not disassembled the Fury X yet
