I understand that you are having problems with your board and you keep on getting error messages.
Regarding this, first I would like to start by telling you that Intel ® is no longer manufacturing boards and they are now out of interactive support. However, I will try my best to give you suggestions as to what could be tried to fix the problem.
According to the information you provided and the details, the only thing I see hasn't been replaced is the processor itself, I would strongly suggest to attempt and swap the processor and attempt a normal post/boot. After this, check if the unit gives you the same errors or not. Also, something that could be tried is to take the BIOS settings back to default.
Allow me to quote from the first post:
" 2. Removing the jumper to place board on recovery mode
With a usb stick containing the BIO file inserted into usb port to update bios WORKS. I see video, I see the fast intel splash screen, I see the steps taking place stating bios is being programmed, cpu microcode updated, until it says "reboot computer" and "replace jumper" "
How can anyone explain the BIOS update works if any of the components on this board (video card, memory, cpu, power supply) are faulty?
The bios update works. I get video on my monitor, it shows the various steps being performed for the bios update, it confirms they have all been successfully updated.
Then I place the jumper in "normal" position (after turning off and discharging) and no video, nothing.

Thank you for your response,
I quite understand your position, however, trying a different processor will be able to let us determine whether it is a hardware problem or not.
This is because you have already done the swapping test with all of the different components except for the processor or motherboard.
If possible, let us know the outcome.
