I agree with RBM. I had this happen once and was at a loss as to where the
problem was. The breakers were all OK but a hallway running past several
bedrooms had lost power, outlets as well as light fixtures. After a bit of
thought, I decided that there had to be a break in a string of lights and
receptacles. I started removing the closest receptacles that had power and
sure enough I found one of the chained receptacles where the hot wire had
obviously gotten hot and discolored the insulation. The person who had
wired the receptacle had elected to use the "push in" connections on the
back of the receptacle, rather than using a loop under the screws. The
connection with the push in had probably not been a good connection in the
first place and, when under power, exhibited enough resistance that it
created heat and eventually burned the connections inside the receptacle off
to the point that the rest of the circuit downstream lost power.

I've never been fond of the "push in" connections because when you push a
wire in you can tell that it's often not really tight and the wire can be
twisted around with ease inside the receptacle. This same thing can happen
with a wire under a screw, but it's not likely if the loop is formed
correctly and the screw tightened sufficiently.

Unless this one receptacle had been replaced, it's probable that most of the
rest of the house is wired in the same manner.

You have an open circuit. Either the hot wire or neutral wire came loose
somewhere in the circuit. Since it only affects one room, its not likely a
circuit breaker problem as there is likely more things on that circuit
then just that room. I would look for a loose connection in an outlet. In
the string of daisy chained outlets, lights and switches, the problem is
likely to be in the last "live" outlet, or the first dead outlet. It
sounds like you've checked all the dead locations, now check "live"
outlets in adjacent walls of other rooms. Sometimes you can bang on the
wall next to the affected outlet and cause the circuit to flicker back on

I have one bedroom in my house that has no power whatsoever. None of
the circuit breaker are tripped, and just to be sure, I flipped each
one to off and then back to on with no effect. I believe that most of
the circuits in the house are spread out among different lights and
outlets in different rooms, so I can't understand why only one room
would be out while everything else is working fine. The house was
built in 1972 and has had no other electrical problems. The problem
occured when the overhead light in the room was turned on. The light
went on, went off, on again, and then off completely. After that,
there was no power at all in the room. The room does not have a GFCI
in it. Does anyone have any ideas what may be wrong? Thanks for any
help you can give!
