Hi, identical problem to Ickier on 3rd August. Except my is not a new build, it was working fine until I decided to disable CMS mode to UEFI as that what I needed to do to allow Windows 10 to upgrade to Windows 11. Now I can't get BIOS setup when I boot. Just goes though the 4 Q LED's then stops on green boot Led.
My system consists of an Asus Tuf-Gaming x570- plus mother board. 512gb SSD boot disk and 2 x 2TB standard hard drives. I've tried all the tricks to erase RTC ram, but just sits on green boot Led. No output to the screen. Holding DEL does nothing. I have a Nvidia graphics card and 32gb of memory. Windows 10 resides on the SSD drive. On reflection I should have pre-prepared the drive for UEFI, before disabling CSM.
Run out of ideas as to what to do now.
