Check your GFI's. One in my garage stumped me for a few days. Reset them all.

You can loose a hot from the pole to your home and every other breaker will not have power.

This. We had an issue with a slowly deteriorating connection from one phase coming into our meter box (occasional unexplained brownouts, flickering during storms, then it finally just failed). As said above you can check this if your box is labeled well: power for all breakers on one side of the panel will be on, the other side will be dark despite the breakers not being tripped. Pepco may charge you for the service call if that does not turn out to be the issue, but their rate should be lower than an electrician giving you the same diagnosis. If you have random outages throughout the panel then it's something else. I would be surprised if a GFCI could cause that much of a downstream outage unless the circuit was dangerously overloaded.

Do you have ground fault outlets installed anywhere?

Go trough the house and reset allnof those.

Outlets and lights are usually on a chain and the l order does not always make sense. If a ground fault outlet trips early in the chain you could have several different areas without power.

Why call Pepco instead of an electrician?

And all the breaks are on. I had some work done in the basement about ten days ago, dry wall removed, recessed lighting installed and new wall is up. I had power this morning in the same places i don't have power this evening. I live alone so fon't know what caused this between the time i left ghe house thus morning and the time I came back.
