hey guys,
I was using my computer one day when my computer started to make this audible buzz noise. it seemed like it was coming from the CPU area on my motherboard I figured it would be the capacitors, but i could hear it across the room and it my caps already have their own high pitched noise. After I heard this buzz, I never heard it again. (by the way i built this computer several months ago)

REALLY WEIRD.

could you guys help me figure out what that buzz could be?

thanks!
