I think you meant "GFCI" and they can go bad or did you test them with a multimeter? I would start there and also test the main service breakers to be sure one isn't passing only part of the AC current across. A meter is about $20 or so at most hardware stores and easy to use and I can direct you in the testing. I will also make a phone chat option offer for you if you would rather do this over the phone.
Just checking back in to see if you got this resolved or do you still need some additional input from me?
