This is a finnicky board. It has wonderful features and runs well, but it's
finnicky.
I've had issues similar to yours (board seemingly dead) and rectified them,
but I never knew for sure what exactly the problem was or what of the many
things I tried that brought it back to life. I started by removing the CMOS
battery for a day (24 hour period to let the caps drain) and unplugged
everything except CPU, RAM and video card. Then try to boot. If you're
successful, plug in one piece of hardware at a time and boot the machine
after each time.
Also, by removing the CMOS battery, you've in effect cleared the BIOS so
you'll have to reconfigure it when you re-insert the battery. Keep us
posted.
