My roommates share a room and they have been experiencing frequent outtages that last anywhere from 5 minutes to an hour. There are 4 outlets in the room, and when this happens only 3 go out. No breaker is switched either. They have 3 surge protectors, 2 in outlets that go out and 1 in the one that doesnt.
In one, they have an xbox, a ps4, 2 monitors, a computer, and desktop speakers plugged in. In another they have a TV, an xbox one X, a headset, and a dyson bladeless fan. In the third, which is in the outlet that doesnt turn off when this happens, they had phone chargers.
I assumed it was caused by too much power draw, but even when most of it was off it still happened. We managed to notice that when you wiggled the outlet that stayed on, the power would come on an off throughout the room as you wiggled. I took the outlet out and noticed that one of the hot wires was slightly exposed, so Im assuming it wiggled and touched the metal in the outlet. It also was slightly charred and looked as if it was heating up too much ("burnt" end and discolored insulation).
I took out that wire and capped it with a wire nut and electrical tap then put the outlet back in. Now the power still hasnt come back on, 2 hours later, but the outlet itself works (not the plug that isnt connected).
Im very confused by whats going on, and need some direction of what to do now. I want to avoid calling an electrician if possible (money is tight) but I also would prefer that over a fire if its an issue.
