Hello, so I recently built a new pc, and so far it has been working beautifully, except for one issue. In the past couple days, my pc started emitting a kind of mechanical buzzing sound. It started out being only like once a day, but now it seems to be there whenever my computer goes to windows, and when my computer is gaming, or even at other random times.

I think it might be the CPU fan, but before I go on replacing it, I just wanted some advice, and to see if you guys think it could be something else (although I checked the case fans and those are fine). Here's my specs:

AMD FX-6300 (the fan it came with)
GTX 760 OC with two fans
8 GB RAM
Corsair CX600W
Asus M5a97 r2.0
ANTEC 300 illusion

Thanks in advance
 
Solution
What I would do is unplug the graphics card, unplug but not remove any case fans, then boot up computer and see where the sound is coming from. Get back to me when you have done it.

Hey so I tried that and i think i heard a little noise coming from my pc, but it's hard to tell, as the noise only occurs when I get to the Windows screen; before that it's not very audible or its nonexistent, which meant that I couldn't test it without the gpu. However, I did find that it wasn't any of the case fans.
I also noticed that the sound only occurs for a little bit; when it goes to the windows desktop screen i hear it for maybe a minute or so, off and on, and then it turns off. It also does this, to a smaller extent, when I open a game or download something, which makes me think it has something to do with the cpu fan, as I heard it a little without the gpu and I don't think that the psu would do it, as I don't believe the power supply varies in intensity or whatnot that much.
So do you have any suggestions as to what could fix it, or if it even needs fixing?

Edit: ok now something just made me rethink this; I looked at my hwmonitor ratings and it says my gpu, an evga gtx 760 oc with two fans, is at 60 degrees celsius when playing far cry 3, whereas my cpu is at 45 degrees, with a stock cooler. This makes me think that it could be the graphics card. Also, the noise was happening a lot when I was in the game, and stopped right when I exited.
However, I don't know if that's been an issue or if that just happened when I put my graphics card back in after taking it out.
