I've had my 2800 for a few months now, but in the past 2 months or so it seems to make a slight "grinding" noise that you'd usually hear from an old hard drive spinning. I have unplugged most everything in my computer and have test the fan on the processor (Thermaltake) and everything else does not seem to make a noise. When I do something as simple as scroll up and down a website the noise will occur. Everything runs fine and I haven't lost performance, the noise is just troublesome and can get annoying at times. Any help is appreciated.
