My mouse cursor constanly freezes-up. It will work for a while but, freezes and I need to reboot.

You didn't say what type of mouse it was, corded, wireless etc. We have no way of telling from here. Have you got any specific mouse software installed? If so it can sometimes play up, so try uninstalling it just to prove the point. The mouse will run with Windows software but lacking features.
Please come back and let us know how you got on.
Try upgrading the driver.
