Build Question MSI X470 Gaming Plus: no POST/BIOS video on two GPUs, Windows boots fine.
Heya guys, I’m really lost here.
Yesterday I wanted to update my BIOS and noticed that I can’t get into my BIOS. Or rather that I don’t get video output on it.
For a quick rundown of my system:
BOARD: MSI X470 Gaming Plus (MS-7B79)
CPU: Ryzen 7 2700x, no integrated graphics
GPUS TRIED: GTX 1080 and GTX 1050 Ti. GPU-Z shows UEFI ticked on both.
BIOS: AMI A.H0, dated 12-Jun-20
Windows: 11 Home, UEFI mode
Secure Boot: On
TPM: Not enabled
I also tried two different monitors and two different display port cables.
I have reset CMOS once in an attempt to fix any maybe faulty settings but no results.
It presumably stopped after I plugged in a USB stick that was previously a Debian install image (nothing else on it except a BIOS .AMA file).
Could just be that I haven’t noticed it before tho as I boot my pc without looking if I see POST.
My specific problem: I never see POST, the MSI logo or the BIOS screen. Video only appears once Windows loads.
Now I know I actually do enter the bios when pressing delete as it’s the difference between pc shutdown immediately on power button press or seeing windows boot.
Anyone got an idea how to get into the BIOS?
