I just bought this new desktop one week ago, everything was fine but suddenly it started to make a very weird noise which is kinda hard to describe. It is definitely coming from than fan, and its like 'tak tak tak tak'. It does not effect the performance, at least i think so, but its just super annoying.
Sometimes the video card power cables can get in the way of the GPU fan, causing a clicking sort of sound.Try removing the video card and make sure to move the video card power cables to the side so that when you install the card again, they do not get in the way of the GPU fan. Click here to view a video that shows how to remove the video card from this system. Let us know how it goes.
