Ive had my AMD 64 3500+ for about 2 months now and a couple of days ago i started getting a vibrating noice out of the cpu fan. It runs fine but it realy becoming annoying, it is pretty loud. What should i do? Ive tried cleaning it using a spray duster thing and it still does it. Ive tried messing with it, but cant seem to fix it. If i have to replace it how hard and what do i have to do to replace it right. Any advice is greatly appreciated thanks.
