Sight along all of the pulleys to see if the belt is peeking out on one of them. In particular, look where the belt goes around the spring-loaded tensioner pulley. If it isn't inline with all of the other pulleys, the pivot bushing is worn and the tensioner must be replaced. 1/8" off-center is enough to cause problems, but usually it will cause a squeal too as the belt slides sideways across the pulley as it goes around it.
