Hello everyone. Let me just say that I am new here and i apologize if i posted incorrectly. I am having some problems with my Radeon 7770. Every time I play a video game or the GPU really has to do any work, the fan emits this annoying high-pitched buzzing noise. It is moderately loud and is at the right frequency to give you a headache. I really haven't touched it or messed with it since i got it in August. I am a little bit scared to take out the graphics card and mess with the fan, as I have never really taken parts from a computer and I am not too tech savvy. This has been happening for a few weeks and it is very annoying!
