More about buzzing again
  1. It could be the video card fan. The video card fans can generate a lot of noise.

    I have an XFX HD Radeon 4770 in my system. When the video card fan operates at maximum rpm I can definitely hear it. It is the loudest fan in my system. When I use the ATI CCC utility to reduce rpm to 50% I can't hear the fan anymore.
  2. Try vsync on.
  3. is not the fan noise. more llike high pitch ringing.

    how do u turn vsync on?and why? the buzzing/ringing is on even when i not gaming
  4. The vsync can be activated in the control panel in this case the Catalyst, the noise is due to the high frame rate of a GPU, enable vsync limits the framerate to 60fps causing less heat to the GPU also.
