Whenever I play games, usually on steam, my mouse will randomly stop functioning for about 1.5 seconds and then begin to work again. But the really weird part is it is still reading all of my movements. I know this because the cursor is where it should be when it begins to work again. So for example if I have my mouse on the left side of the screen and move it toward the right side at a consistent speed and it stops working at the middle and I continue to move it toward the right, the cursor is on the right edge of my monitor when it begins to work.
