Incorrect tension, or contamination. A bad bearing in the alternator, A/C compressor, etc will cause excessive stress on the belt, and it will squeal as is slides over the stiff parts. Also, serpentine belts are very sensitive to grease or oil. DO NOT use traditional V-belt dressing on a serpentine belt. The least it will do is squeal. At worst, it will pop off while the engine is running and you're under the hood looking at something. They have quite the bite when they let go.
Worn out serpentine belt and/or belt tensioner.
Yes check your compressor!
