I have a whining noise on the driver side. I was told that it was the power steering pump and I replaced it. But,the noise is still there.What else could cause such a noise ? It's louder when I'm driving.

It could also be the ac compressor clutch. I had that same problem on a SLK and we replaced the power steering pump. The noise was still there.
We bypassed the ac clutch and the nosie was gone.
Try to identify if it is the ac clutch. You can remove the belt and run the car for a min without any belt. Note that you will get several warning lights on the instrument cluster.
