I can confirm the Alpha's solution works. Not that I was using a riser cable. I actually thought of it last night. I had tried forcing PCI-E Gen 4 and still had the issue but later it occurred to me this might be the video card's problem and not the motherboard's so I set PCI-E Gen 3 in the bios and low and behold it booted. I have contacted AMD regarding this issue. I might update this thread once I get my hands on another x570 motherboard, see if this is exclusive to the Aorus or any board.
Thanks for the help!
