Battery light came on and lost power steering

Yay more problems!
Heard some noises today when driving to and from work but thought it was the suspension.

Anyways, when i was a street away from home (i was listening to music but i heard some noise) and the battery light came on and lost power steering.

Anyone have it before?

I left the car in the garage and had to go to my second job (where i am at now)

Car didn't over heat, and the power steering fluid shouldn't be an issue..

Serpentine Belt?
Idler pulley?
