Hello John,
I don't know if the mouse is optical otherwise if it's PS2 you have to clean it.
Remove the ball and clean the two little bars and the wheel.
With an optical mouse the underground is important, use a white sheet of paper to try.
Did you try another computer port if the connection is USB?
I don't think it's a driver problem because Windows recognizes all common mouses.
If it doesn't work I think you have to buy a new one.
Succes and greetings,
Henri
