Are you using an after market belt? Or the cheapest? Opt for original equipment or a quality belt at your local parts store. Not all belts work . Let the buyer beware.
It could be a too long belt, a failed tensioner or incorrectly adjusted tension, incorrect belt routing, failed pulley, out of the line accessory. Can you feel any movement on the pulleys when the belt is off?
