I'm building a gaming PC using an Aorus X570 MB, AMD Ryzen 5, AMD Radon 580 GPU, Seasonic PX-750 PSU, and 2 XPG 8GB ram chips installed in a dual channel configuration. I've installed all the components and powered up the system. Everything boots up but I have no video output on either the MB HDMI output or the GPU output. To the best of my knowledge all the cables are installed properly but the documentation to must of these components is pretty vague. Any ideas would be greatly appreciated
