where abouts on the mobe is the black square?
The chipped black square is likely a MOSFET, or power control transistor. When they get too hot from over-voltage or current, the black epoxy that they are made of will often fracture, and the broken piece will frequently go flying. That was probably the bang that was heard. The smoke likely came from that component, or other components that were supplied any voltage or current from that device down the line.
EDIT: @ illway1:
I've attached a screen shot of your mobo. Which area was the broken part located in?
