The codes I have been getting are: A0, A9, b6, bd, and, A2. When I update BIOS via USB drive, it completes successfully. I changed all booting to UEFI but it didn't satisfy Windows 11 requirements. Then completely disabled CSM and now I get nothing on the monitor - aat all.
results in the Q code changing but then settles back down to A9. I have a GEForce 1070 that I have physically removed or just unplugged power - makes no difference. I don't think I have another video card to try as all previous MBs have had onboard video.
