Black screen after BIOS 3205 Update

[drpuffypants]

I have a Z690-P. I ran a bios update that went properly through all the steps, but when it restarted the computer the screen never came back up and the power button flashes once every two seconds.

I have tried so far. Removing everything from the machine except the ram and the CPU. Still no video via the on-board video. The LED power light still flashes once every two seconds. I have tried flash recovery with several different USB drives, but nothing happens when I plug them in on boot.

I am at a loss what to try next or just assume my motherboard is hosed.
