Question about HP PC Desktops
By power box do you mean power supply? if so then the fan inside your power supply is probably clipping something as it rotates. I would suggest replacing it because if its not the fan then its failing. If you dont mean power supply just your PC, then it would be the same, a loose wire or something is rubbing one of the fans inside the case, either a cooling fan or the cpu fan.
