Check your belt, belt tensioner, and idler pulley.

do you have a hyrdoboost setup? you may have broken the pump shaft, you can check this by taking the belt tension off the power steering pulley, with the tension off pull on the pulley like you are going to pull it off. It shouldn't move, if it is broken it will move if not come all the way out. Breaking of the shafts are pretty common, and could cause both issues you are having.
