If it were me I would first turn everything off. Shut down computer, power supplies...everything and then use a multimeter to check continuity of the Z-axis wires and connectors as well as any limit switches you may have. Also try and slowly turn the motor shaft by hand to make sure nothing is binding. But be sure to go slow so you don't back feed the driver with current.
If you don't find any problems there you can try swapping the Z-axis motor into the drive for another axis, like X or Y and see if the motor will turn. That should tell you whether its the motor or the drive.
Let us know what you find, good luck!
