Hi everyone,

I’m currently experiencing multiple issues after updating my BIOS and would appreciate any guidance from the community.

System Specifications:

Motherboard: Aorus X670 Gaming AX (Rev 1.0)
GPU: Aorus RTX 3080 Master 10G
RAM: DDR5 HyperX 5600 MT/s
PSU: Corsair HX850
AIO Cooler: Aorus Waterforce 240

Issue Summary:

Over the past weekend, I updated my BIOS from version F38 to F40 (and later tested F41a). Since then, I’ve encountered several problems:

1. Boot Issues / VGA Debug LED

During startup, the system occasionally gets stuck on a black screen with a blinking underscore (“_”), before the Gigabyte logo appears.
At the same time, the VGA debug LED turns red on the motherboard.
The system sometimes eventually boots after reseating the RAM and GPU, but the behavior is inconsistent.

2. AIO LCD Malfunction

My AIO LCD initially turns on and displays the default startup animation.
Once Windows loads and my custom GIF appears, the LCD screen turns black and remains off.

3. Significant Performance Degradation

Prior to the BIOS update (F38), I was able to run games like Minecraft at unlimited FPS smoothly.
After updating, performance has dropped significantly:
- I now need to cap FPS at 60–120 to maintain stability.
- Running at uncapped FPS results in severe lag (feels like 5–10 FPS).

Additional Context:

Previous BIOS updates via Gigabyte Control Center were completed without issues.
These problems only started after updating to F40/F41a.
Hardware reseating has helped temporarily but has not resolved the root cause.

Concern:
At this point, I’m unsure whether this is purely a BIOS/firmware issue or a potential hardware fault. I’m also not confident using the system long-term in this state and am considering a warranty claim for the motherboard.

Question to the Community:

Would it be safe and advisable to roll back the BIOS from F40/F41a to F38?

I’ve received mixed information—someone mentioned that BIOS versions cannot be downgraded once updated. Can anyone confirm if that’s true for this board, or if a rollback is possible using Q-Flash?

Any insights, similar experiences, or recommended steps would be greatly appreciated. Thanks in advance.

Hey everyone, hoping to get some help here.

I recently updated my BIOS using Gigabyte Control Center, and ever since then I’ve been running into issues. Before the update, everything was working perfectly fine. It still somehow boots after I turn off/on the PSU but when I tried to shut down and reboot, it shows no display as above.

Current problem:

PC gets stuck on a black/blank screen before the Gigabyte logo appears

I’ve waited ~10 minutes and nothing changes

Motherboard shows a red VGA light

My specs:

CPU: AMD Ryzen 9 7900X

MOBO: Gigabyte x670 Gaming Ax Ver 1

RAM: 32GB DDR5 (2 sticks)

GPU: Aorus RTX3080

RAM configuration (not sure if relevant):

Currently installed in slots 3 & 4

I was advised by the PC shop to use this config to achieve 5600 MT/s instead of 1 & 3

Been running like this for years without issues (before BIOS update)

What changed:

Only thing I did was the BIOS update (F40 to F41e)

Oh and after the update, it still shows F40 but then I q-flashed it to F41e the problem still persists.. I thought I had a corrupt update but since I've updated to F41e I thought it's been completed?

Questions:

Could this be caused by the BIOS update?

Is the RAM slot configuration a possible issue now?

Does the VGA red light mean GPU failure or just a POST issue?

Any recommended steps? I did CMOS, QFLASH for the update from F40 to F41e (note that after the update, the BIOS shows F40 then i updated manually by qflash this still happens)

Would really appreciate any advice—getting a bit worried since it was working fine before 😅
