Built this PC a few weeks ago, but all of a sudden a loud crackling noise has appeared whenever I start up the PC, or install a game and continues all the time while running. I have isolated the sound to the power supply. The strange thing is that whenever the PC makes the sound, the light in the power button which usually goes blue, flashes little orange dots. Desperate for help.
EDIT: I have tried using different SATA ports and cleaning filters
