Q: my computer mouse is pretty old and for some reason the roller ball doesn't want to roll very well. it sticks and you have to move it really fast to do anything but even then it doesn't work to well... any ideas? i have taken out the ball, unscrewed it and everything,but its not working. a wire with a coil in the middle fell on the floor and i don't know if it is from the mouse though...
A: take the ball out and clean it and scrape the inside free of dust
