That sucks lise! stuff like that is normally one of the breakers. Best way to check that is like what miss Puresexxylife says.. with a voltmeter. I carry one in my truck even, lol.
Check at teh outlets and check the power going throught the breakers on teh output.. careful though, as it is live.. I have shocked myself many a times, lets just say it keeps your heart beating and you on your toes.
If its not that I would say you might have a short in one of your electrical connection boxes.. you might end up having to pull the covers and outlets out to see the electrical connections. By the houseing code all connections have to be done in a junction box that can be accessible without ripping the walls down. Most problems like that is either breaker or connections in the junction boxes. If its worse then its one of the feeder lines to teh outlets, and thats a major suck. You have to take down some of the walls to get at the feeder lines.. and the worst part is you dont knwo which way they've been run.
