Your hard drive may have too much running (foreground or background) Check for updates and also check your virus protection. Some can get nervous on some sites, resulting in irregular or stumbled movements. Also, check the mouse settings in your Control Panel. I recommend removing trails and setting motions speed that work more smoothly.
