Motherboard has been functioning normally and stable (Except for the USB issues) since I bought it September, 2014.
Then yesterday pushed the power button and it would not start. Noticed the yellow power light on the board would flash on when I flipped on the P/S switch and go out. Put in new BIOS battery and I got a solid yellow light now. Push power button, would not start. Replaced power supply with a known, good one, and still would not start.
Thinking OK, I got a dead motherboard here.
Cuss a few times, unplug, unscrew, remove. Cuss some more. Check warranty return procedure. Motherboard sitting in box ready to return. HHMMMM, let me check it one more time. Plug in original power supply. Push on board power switch... and all the fans and lights spring to life. Now cussing because I have to put it all back together again.
It's back to functioning normally again
Anybody have this happen or care to speculate why it did what it did?
