Unresolved Bad Ramps board, motor or both?

Was running a print and the extruded started making horrible noises, stopped the print and checked it out, pulled the gears off to make sure nothing was striped out and everything was turning fine. Used the xxl screen to jog the steppers and all worked besides the extruder motor. Decided to swap it on the ramps with the x axis and then the extruder would only run 1 direction and the x wouldn't move. Only had the printer about a month now so still in warranty. This is the R1+. What could have caused the board to go bad this fast?

 

well I had a few mins this morning to mess around with it and was swapping around the cards and that did nothing for the issue. I did try the extruder motor on a different wire set and it worked fine, but the wires have to be bad as when I tried them on another motor in a diffrent spot then the motor didnt work. I also noticed my z axis will go up fine but not down at all. I am going to guess the ramps board fried when the wires shorted or broke.
