  1. Clean the sensor on the mouse and clean the mousepad. You probably have a hair or some other debris on the sensor.
  2. or use another surface to sit under the mouse, the other symptom can be an over worked Cpu or to much running at the same time on the computer. If you are using an old ball type mouse you need to drop the ball out from the underside of the mouse and clean the roller bars inside where the ball fits, as there will be chunks of dirt on the rollers.
