In the living dining room several outlets and two overhead lights are dead.
At the service panel I checked all the circuit breakers outputs for power, and all are live. I also checked every GFI circuit in the house I could find and tripped and reset them all. I still have no power on the aforementioned circuits.
I also loosened and tightened each breaker screw holding respective wires, both at the breaker switches and neutral wires.
Still no power.
