About an hour ago the power suddenly went out in one room. The overhead light was still on, but none of the outlets are working. I turned everything off just in case and went to try the circuit breaker, but that didn't work. Then I unplugged everything, but that also didn't work. I felt the walls around the outlets just in case something behind the wall caught fire, and I didn't feel any heat (although I have to say I'm happy that I didn't... ). Before it went out, I had a little heater on, and about half an hour after I plugged it in, the power went out, so I think that might have something to do with it. I unplugged it as soon as the power went out and tried to use it in another room and it worked just fine.

The house is about 20-30 years old, and none of the outlets are GFIs.
