Does anyone know about how lightning enters a home without being a direct lightning strike to the house?

When lightining strikes the ground/trees closeby our home, we hear popping noises (like light bulbs blowing, small explostions kinda)in our house. Our breakers in our bedrooms kick. Our lights in our ceiling fan light up (with the switch OFF). We've had our local power company check everything, and they found nothing. We had an electrician come down and check and even put in an extra copper ground rod near our meter base. We can't seem to get anyone to determine the cause of these problems. We built our home three years ago. We had NO problems until after we had lived here for 2 years. I appreciate your help!
