[neverending]

This part:

It was in black in white
The central character was a young blonde woman. The ghost in the house were after her and she died in a car trying to escape the grounds

is definitely The Haunting.

This part:

I remember there was an old woman who banged on the side of the house with her cane when she needed her nurse. One day the nurse did not come and the old woman died. The ghosts then drove the nurse crazy and she hung herself.

is definitely NOT The Haunting. You may have two movies mixed together. It's been known to happen!
