That said, is the AMD GPU not posting anything, not even BIOS?
But the BIOS posted with CSM on, as the GPU didn't have any UEFI drivers. This went away after I had installed the drivers for it and then I could take CSM off.
Hey momo, thanks for the reply. I tried CSM on and off no post. I've tried 3-5+ times to see if posts.
AMD GPUs (both the 6800xt & 7970) don't post to bios while the Nvidia does post to bios and windows.
Used DDU in safe mode. I've used DDU multiple times during this issue to see if it would post without any drivers, but no luck.
Windows update is paused since fresh windows 10 install. Should I unpause?
If bios causes issues ill track back.. but now I just need a post.
Every time I plug in the Nvidia - if the American Megatrends screen pops up telling me all my recognized hardware. It says "The VGA Card is not supported by UEFI driver" and it changes CSM to on.
I've just opened DDU to see what it recognizes. It first tells me the Nvidia's drivers and stuff. Then goes on to AMD:
GPU #001 - Detected Microsoft Basic Display Adapter
GPU Deviceld: PCI/CC_0300
Vbios: NAVI21EXT
Driver version: 10.0.19041.1
INF: Display.inf
INF SEction: MSBDA
So im guessing it does have some sort of driver there. maybe it's corrupt?
Ill try ddu this driver now and restart with CSM on, maybe this combo will work.
