One wall of our home lost all electrical power. We flipped the breakers and nothing happened. One day we had power and the next day we didn't. What would cause this? What are some things we can try before we call a professional? It is the entry wall connected to the garage... if that matters. Thanks!

Do you mean that the outlets are in the garage?

Yes, there is an outlet in the garage and it isn't working. There are also two switches and an outlet on the inside part of the wall that are not working. One switch turns on three small lights that light up three separate alcoves and the other switch turns on a water fountain which is in the middle alcove, but we never turn that switch on.

Are any of the outlets GFI?
