Hello. My computer has suddenly begun to give a EEEEEEEEEEEEEEEEEEEEEEEEEEEE sound even when off. Probably not the processor not sure if it is the GPU or PSU. How would I go about finding this. I mean I guess I could get a mechanics stethoscope. What would be the better method on the component level after i crack open the offender? Is it always a coil or could it be a capacitor? I also have a Xbox Controller that just decided to die last night. When it rains it pours I guess.
