Assistance with X axis shift

Hey guys, so this is my first post.
I bought a Geetech Prusia i3 Mk2 around July 2018 (second hand so i did not build her).
She worked perfectly for a while, then i moved to a new place and that's when the issues started.
During printing the x axis (extruder) moves all the way to the right until it can no longer go, but it continues to print, it starts from the first layer.
I have tried using a different slicer (I currently use Cura)
I checked the x and y axis belts
I checked the rods for any obstruction, and manually moved the x axis around and it was fine
I have checked and re-checked the wiring
I tested it by printing from the PC and using an SD card - same result
I even set the printing speed down to 30mm/s, and increased it in 5mm/s increments and there was no improvement
I also set the movement speed down t0 60mm/s
I checked the main power cable running to the printer and even tested it running on a brand new cable and no improvement
It never slips to the left

What could be causing this issue?
I am running out of options and any advice will be greatly appreciated!
