If that doesn't solve your problem, you might want to deactivate your mouse software and see if that solve your problem.

If nothing solves your problem, you might want to give more détails about your computer (o/s being used, peripherals attached to your computer, msconfig startup page content etc). Not knowing anything about your computer environment, makes it extremely hard to give any accurate help.
