Stepper motors not working

Hi
I have installed Marlin firmware for ramps 1.4 board and now I'm trying to calibrate my printer but I have little problem.
My motors not turning when I’m trying to move them on calibration. I have tried every wiring combination, adjusted potentiometers but motors are just keeping some kind of high frequency sound when I’m trying to move them.
My stepper drivers are DVR8825
This is a new printer and motors cant be burnt because I have tried to move them for only few seconds. Here is video from my problem:

How did you set the microstepping jumpers and what "steps per unit" are you using for the axes?

Could it be that you are driving the motors much too fast, e.g. jumpered for full step but firmware configured for 1/32 step?
