check the tension to make sure that it is not to tight or to loose, if you can twist the belt 180 degrees, it is too loose, if you cannot twist it at least 45 to 90 degrees it is to tight, also check to make sure the belt is aligned correctly on the pulleys, hope that helps, if not try the bottle of belt dressing, auto zone or somewhere like that should have it.
