  4. Does any of the debug LEDs turn on when starting the board?

  6. Why haven't you installed the CPU cooler?
    And I can't see if the 8 pin power cable is connected.

  8. I suggest taking the board outside the case, connecting both 24 and 8 pin power cables, CPU, CPU cooler and internal speaker. No other wires/components.
    Start the board by shortly touching with a screwdriver the 2 pins on the board corresponding to the case power button.
    See if the CPU fan does spin and if any beeps.
