What's that noise
Happened last Sunday. Customer called me complaining that for the last two weeks she had been hearing a constant ticking noise coming from her desktop and smelling something electrical overheating every once in a while. I suspected a fan giving up the ghost and told her to shut the computer down and to bring it to the shop in the morning. She powered down the system and announced the sound was still there even without the computer running and with that she insisted I come out and find the problem.
I arrived at the customers home, walked into the living room where the computer was located, walked to her desk reached up, took a battery operated clock off the wall, walked to the opposite end of the room and asked her if she could still hear the noise. She turned beet red and said, you are going to tell everyone about this aren't you? Please do me a favor and do not tell them it was me. Then she said I could go now... The overheating electrical item? A power transformer laying on a heater outlet, Oh, she had bought the clock at a tag sale two weeks before...
