I have two video cards in my computer. When I connect my monitor to my old GTX 780 GPU the BIOS screen is skipped during boot and goes straight to the home screen.
When I connect my monitor to the new RTX 3070 GPU, the boot process is normal and the BIOS is not skipped.
How can I make it work with my old GPU? Actually, it worked fine before I installed the new GPU.
My motherboard is Asus P9X79-E WS
