Unable to start from BIOS for Ryzen 7800X3D model
Unable to start from BIOS for Ryzen 7800X3D model
Just an update, i think i found my problem. The problem on my end was my GPU (RTX 4090). When i used an HDMI cable connected to the motherboard i would get picture. When i selected the DP from my GPU i would get a dark screen. Perhaps we can fix it by changing the CSM in bios or changing UEFI boot mode to Legacy or the other way around.
This appears to be connected with activating EXPO. Turning it off prevents me from using the BIOS button or the Shift+Restart method, while turning it on blocks those actions. There seems to be a reason behind this behavior.
