Hello! I haven’t posted before, so apologies if I do something wrong, and please correct me!

GPU: SAPPHIRE AMD RADEON RX 7800 XT 16GB GDDR6
TLDR; My PC won’t reach the BIOS when the PCIe power cables are plugged into the GPU, although the GPU’s fans spin when the computer boots without the GPU being plugged into the PSU. The integrated GPU works fine.
I’ve tried reseating the GPU, shorting the CMOS, flashing a new BIOS (updated to 1.IO for MSI B650 Tomahawk Wifi motherboard), updating AMD GPU drivers on EnOS, and (kinda?) updating the drivers on windows via the AMD website for my specific graphics card (the auto-detect and install tool always errors out for me, I am a toddler when it comes to Windows lol).
On EnOS, my radeon/amd drivers are…
paru -Q | grep 'radeon\|amd'
amd-ucode 20240703.e94a2a3b-1
lib32-vulkan-radeon 1:24.1.4-2
vulkan-radeon 1:24.1.4-2
xf86-video-amdgpu 23.0.0-2
Some context:
I dual boot Endeavor and Windows, with Windows installed after Linux. Windows (in theory…) updated itself unprompted after I walked away from my PC (I was gone 2 minutes tops. Grr.). When I came back, my screen was black, and my peripherals wouldn’t do anything. Having had weird GPU driver issues in the past which often are resolved by restarting my computer, I powered it off.
I eventually unplugged the GPU while trying to debug the boot issue. My PC then booted into Windows, where it said it was finishing an update, hence why I assume Windows was updating, although I’m not 100% sure since I did quite a few debugging steps (CMOS, reseating ram, etc.) between then and when I found out my computer wouldn’t boot.
Windows overwrote my EFI partition on my EnOS drive, which I’ve finally fixed and now have EnOS set to the default again. I was hopeful that fixing my EFI would’ve resolved the GPU issue, but alas…
Because the GPU was working earlier, and because Windows seemed to have updated and messed stuff up when I interrupted it, I’m hopefully thinking the problem has something to do with my EFI configs or the BIOS itself, but I’m pretty stuck and don’t know what to do. I’ve written to Sapphire since the GPU is still under warranty, but I’m wondering if there’s anything else that could be wrong/fixable.
- the initial boot to BIOS/UEFI has nothing to do with the host operating system, at that early initial stage neither windows nor linux would be involved in any of the boot processes.
