If you have a wireless mouse, low batteries can result in weak, mixed or no signals that can affect its functionality so start by replacing them. If that does not help, confirm that the mouse works on another machine. It is possible the mouse could be defective causing the erratic cursor movement. Another thing to try is to use a different mouse or a PS2 adapter if its a USB mouse.
