I have an office in my basement, It all was fine and out of the blue, I used the microwave (which I do every day) and the entire west end of the basement went dead. NO popping or any warning. I checked the breaker and it was not tripped. So I reset it anyway and still no power to the outlet. Any Ideas??

I would look for a GFCI (Ground Fault Circuit Interrupter). This may be upstream from the microwave outlet, so check each outlet that has no power. Press the reset, and you should be fine.

Let's just hope that is all it is,
