I custom built this PC in February and have had no problems what so ever up until now. Then a couple of months in my GPU fan started making a clicking sound every once-in-awhile, now it is nonstop. I take the GPU out and try to determine what is making the noise. After re installing the GPU I get this loud continuous audio interference on my speakers and headphones which occurs even when the computer is powered off. It sounds like a jet engine and no audio will play now at all.
