Sorry i thought this was a fresh drive with nothing on it.
Just noticed you flashed the bios with the CPU installed. You could try removing all the components and flash the bios again with nothing installed except the power cables. (24pin and 8 Pin, not sure if you need the 4 pin as well)
Sorry to be more clear it is a complete fresh drive. I just have a old ssd from my last build with it on.
I flashed the bios twice. I did it once with the CPU installed then later tried it again with nothing but power in. Gave me the same result, past the CPU led and onto the boot.
