I just barely reinstalled my Windows 7 computer, and have transferred my files back to my computer from an external hard drive. I decided to sort and delete unused files, when eventually my mouse movement started to move very erratic.
Moving to the left seems to cover less ground, while moving to the right seems to work normally. Up and down has the same effects as left movement, which is why moving to the right isn't always smooth or perfect.
I am using a wired Razer Deathadder mouse (left handed), and have the correct drivers
installed. I have restarted the computer but I still have the same symptoms! This movement is very annoying, and I'd like to know what is causing it.
