Hello,
It sounds like the serpentine belt makes the screeching noise when the engine is cold.
It makes the noise as it slips on the pulley. When that happens the power steering pulley does not turn and the pump does not provide turning power to the steering wheel.
When a serpentine belts wears off it will glaze over and will slip and that will do the screeching noise, typically when cold.
