Electrical: Outlets Not working - no Tripped Breaker

[Andrew B.]

Can anybody recommend any trouble shooting steps that I can pursue, before I call an electrician?

All of a sudden, all the outlets in my master bedroom stopped work except for one plug in one of the outlets (two plugs per outlet).

I tried resetting all the breakers just to be sure, and that didn't fix anything.

I'm comfortable with DIY, but electric is something I usually leave to professionals. I'd be comfortable replacing an outlet if I had to or maybe testing with a multimeter, but anything else is getting a professional.
