I used to hear a squeaking noise when I turn my wheels, I fixed that by putting an anti leak power steering fluid. There were no sounds for couple of months. But now, when I start the engine it sqeaks like hell and when I start driving or it idles for a couple minutes, the squeaks stops after sometime. I am not sure why? Any help is greatly appreciated. (Toyota Camry 97, has 130K on it)

Something that is belt driven is putting a large load on the engine. Power steering pump, alternator, or air conditioner or an idler pulley can all do this.
