You didn't mention the alternator, power steering pump, or water pump. In fact, any pulley other than the crankshaft one can have a bad bearing or dry seal. Remove the belt and spin each pulley while listening for any rough noise or squeal. If it was the crankshaft, it might be time to check the oil. Start the engine with the belt off to see if it does squeal. Make sure the noise isn't coming from the radiator fan(s).

serpentione belt sounds as if it is stretched. first try to reseat serpentine belt. if still a problem then go buy new belt at autozone. also buy some belt dressing. this should fix the problem. if this doesnt solve then you need to buy a new idler arm. relatively easy fix.
