Why does the touchpad or external mouse move by itself? Sometimes it moves off the screen. It is Dell Latitude C600 laptop. It appears to be a hardware issue but not sure if system board.

you should install the latest bios update
and you can set the mouse options in the bios.
I had the same with my latitude and now it is fixed.

Check your device manage and see if the IRQ assigned to the touch pad is in use by any other device.
