Had a machine - loose screw.. checked the machine and returned when working okay.. now the mouse is 'jumping around' the screen. any idea? it used to use a 'Browser Mouse' application, which i uninstalled. i think it might have a short on the board now. Any ideas - i need diagnostic software to download that will test the hardware components ie board cpu ram drives cards etc.
Urgently required.. please help..
