It sounds like it's just one circuit as the other electrical
devices are working. I suggest checking the GFI(s) again; you have to first trip them, and then reset them, so that's two buttons to push.
Similarly, you want to first shut a breaker all the way off, and then flip it on again in order to reset it.
Other than that, you have an open circuit. If you have a meter, you can trace it from the source and from there downline. Normally an open circuit occurs within a failed device (less common) or at the point of connection to a device (more common).
