Help Me Find This 80's Horror Movie Title?

Can someone help me find the title of this old horror movie. All I remember is that its set in an old house. A lady walks into the attic and to a large window. The floor of the attic starts tearing apart forcing her closer to the window. Outside it is an old stone fountain. I believe she eventually is thrown out the window and dies. PLEASE HELP. Been trying to figure this out for years.
