Ryzen 5600G - ASUS TUF GAMING X570 PLUS WIFI - Won't boot without a graphics card installed.
I have an ASUS TUF GAMING X570 PLUS WIFI motherboard and a Ryzen 5600G processor.
I want to set up the system using the 5600G's onboard graphics, but I can't get the system to boot without a GPU installed.
With a GPU installed, but the HDMI cable plugged into the motherboards HDMI socket, not the one on the GPU, the system boots and I can get into the BIOS. However, if I remove the GPU the system won't start, the fans spin for a few seconds, then nothing.
My motherboard does have some boot sequence status LEDs:
With a GPU installed, it goes through the sequence to BOOT, without the GPU the DRAM light comes on briefly, then goes out and the fans stop spinning.
I've updated to the latest BIOS version and all seems well when there's a GPU installed.
