special effects house

Does anyone remember a haunted house/possessed film from 70′s 80′s where a family move to country house?
I watched this film as a child and it scared me and just recently I remembered it but not the name. It starts off with a family buying a house in country somewhere and they have a party but the guests driving back are killed in bad special effects car accident. The husband works in city and weird stuff happens to wife and child like they float when she conducts seance and she gets spooked in garden. In the end I think the husband is giving a board meeting with projector and he see’s a pic of his house with two yellow devil eyes in. This does sound retarded but its all I can remember. lol
thanks for answers guys. the friends that died didn’t haunt them, they just died. The husband worked away and the wife and child were spooked by ghost/house and then when the husband see’s picture with ghost eyes in he rush’s home to save them. maybe i dreamt it….
Found it!! It’s called Something Evil (1972) by none other than Steven Speilberg
Not Amityville? sure?
Burnt Offerings (1976)?
