Power steering on 1998 Eclipse

:cry:
My 1998 Eclipse makes a horrible squealing noise each time I turn the wheel that is progressivly getting wrose to the point that if I turn it at all it makes that loud noise in the front of the engine. I have been having trouble with power steering, one belt I had broke. So I had a buddy put in a new one that also broke. And this third one seems to be fine. The car is not hard to turn but the noise is horrible when it does turn (extremly loud!). It started about two weeks after I replaced the last belt. Every once in a while it will be hard to turn like the power steering is out but not often. What is this horrible noise from!
