Cursor is frozen on start up?

Check your mouse cord to see if it's plugged in all the way. If it's of PS/2 type, the little needles may need to be straightened if you plugged it in too excitedly a few times. Some needle-nose pliers and some TLC should do the trick. Also, if you plug in a PS/2 mouse while the computer's on, you'll need to restart in order for it to work. If it's USB, make sure there's no junk in either the plug or the connector and try again. There may be a problem with that USB port. Try another one. Another thing to do is clean the mouse. If it's an optical (laser) mouse, make sure there's no hair on the lens. Use a dry, clean, soft, lint-free cloth, just in case. If it's a mouse with the traditional ball, take the ball out and clean the little rollers with an (unused) ear cleaner and some cleaning solution. Still have problems? Make sure the cord isn't frayed or broken anywhere. If it is, or if nothing else works, throw it out and buy a new mouse! If you just can't live without your specific beloved mouse and don't want to buy another one, see if you can find a loophole in the manufacturer's warranty. Otherwise, you're out of luck! P.S. If you ever upgrade to another mouse for no real reason, don't throw the old, working mouse away. Instead, keep a supply in your basement or somewhere for when calamities such as this one strike.
