Do you have any GFCI switch outlets? If those are tripped, the other outlets along the line go out too. Just press the reset button.
Some houses hide one in the garage. My bathroom and outside power went out. Forgot all about the garage gfci which was behind some junk. Felt stupid once I found it and remembered since I had fiddled with the fuse box and bathroom gfci trying to figure out what was wrong.
