Assembled, reassembled everything, does not boot, no sound, either pressing the programmer's button.
Of course you knew only press the CUDA switch just once, holding for 10 seconds release, and, not to press more than once. Pressing repeatedly may interfere with the reset process. (The reset takes about 15 seconds).
No chime = failure of POST (power on self test) So I'd start by rechecking the seating/connect
