High Pitched Buzzing
Starting about a week ago my computer speakers have been making a really high pitched buzzing.Its very loud and I can even hear it through music. I'm almost positive it is not the speakers because if i plug a pair of headphones directly into the computer, they too get this annoying dastardly buzzing. I'm also pretty sure, but not positive, that it is not the onboard sound card because I get the buzzing even if i use an extermal USB sound card. Another thing is that the buzzing seems to mimic whatever the harddrive is doing at the time.
I'm currently using an K7N2G motherboard.
Help would be greatly greatly greatly appreciated.
