I have a circuit that has 2 outlets and an overhead light on it. I noticed the other day that neither of the outlets, nor the overhead light are working. I checked the breaker and it hasn't tripped, so I'm trying to determine what happened. I do recall that a keyborad was plugged into one of the outlets and ever since then the outlet seemed to only work intermittantly - but now nothing is working. Could the keyborad have caused this?Any advice on fixing this would be appreciated.
