Slow your print speed right down as slow as you can so that you know you are certainly not driving the steppers too fast.

Your video is not good enough. What are you doing to make it do that? Are you using the printer panel to try to move it? Does your extruder make the same noise? Have you changed the stepper for a different one? Have you tried a different slot and a different driver board?

In cases like this you just have to methodically go through and eliminate pieces of the puzzle by substitution if you do not have the electronic know how to diagnose properly.

As a first guess I would say your problem is that you bought Geeetech stuff and everything they sell is complete and utter rubbish.
