Here is how to change the direction, https://www.vicious1.com/reversing-the-axis-direction/.
The whine is normal, so do dome don’t as much.
With the power off and disconnected change the y axis to the X axis on the ramps board. See if the problem stays with the board or the axis. It could be as simple as your belts are too tight and not letting the steppers move. Have a detailed look at everything. I test the boards on my machine before they leave here so Chances are pretty good it is not that. Make sure never to unplug any wires while the ramps is powered up. Easiest way to fry it.
