Could really do with a hand, I'm getting no signal to my monitor when I try to start my new rig, can't enter BIOS to set the windows install USB. MSI B550 Tomahawk, 3600x, 32gb Teamforce Vulkan 3200mhz RAM, Corsair RMx750 PSU, GTX 1080. I've tried an alternate monitor, alternate cables, different ports on the graphics card, different RAM configurations(normal furthest-with-a-gap, the reverse, next to each other in all possible ways, and both sticks tested singly in every slot), I used the single bifurcated PCIE cable that came with the PSU and is ostensibly the standard, I used both bifurcated PCIE cables but only the primary connector of each, and I switched back to my old 750w EVGA PSU with two single PCIE cables for the GPU.
Every single time the machine starts up, it cycles through the diagnostic LEDs(CPU, MEM, GPU, BOOT) and stays on BOOT, which is expected without a proper boot drive. All case fans work, the GPU is lit and does its normal test spin of the fans, and the Wraith cooler that came with the CPU is spinning fine. I know the graphics card isn't the problem, because it's from my previous rig and I'm using it again right now on that to type this. I'm genuinely at a loss.
