I just got a Sapphire RX 580 Nitro+ GPU, I installed it on my MSI motherboard but I get no signal at all, I cant even get into bios. I am coming off a GTX570 GPU. I am at the latest BIOS. I understand the GPU is a UEFI card, is there anything I need to do in my UEFI/BIOS? EEFI does work because I was able to create a UEFI Windows 10 bootable drive. The GPU is used but is advertised as working.
