Step motors vibrate, don't move at all (Prusa I3)
Usually if they get too hot you have to adjust the amperage by turning the little potentiometer on the A4988 (turn left until you can move the motor by hand, turn right until you cant, add a little bit like 1/8 to 1/4 of a turn).

But this:


  I used a different stepstick RAMPS card and Mega, they worked perfectly.


it is not completely clear, so:


the A4988 work on another board -> your new board is broken
another A4988 worked -> the A4988 is broken
