PC makes buzzing sound

So my pc has been making this buzzing sound for probably more than a year now and its driving me nuts. I really don't know what to do and don't have a solution for it. Sometimes when I try to stop it temporarily, I just lift up the pc or give it a good punch and it will stop for a bit and then continue buzzing. What might it be that causes this? Thanks in Advance.

Is it on/off, or only when under load? Check inside to see whether any cables are touching fan blades. Also, if it is only when under load then thats normal. Its called coil whine.

It happens at random times. Sometimes when it is just running on the background and other times when I'm gaming. And I've already checked for any cables touching fan blades and didn't see anything.

there is an extremely high chance that it is a Fan, if anything else made that kind of buzzing sound then it would have died month ago. it could be one that's dying/falling apart.

how long have you had this PC?

Actually, coil whine is not necessarily a symptom of impending hardware failure.

I though coil whine was due to power going through a cable? Would that be a constant buzzing sound, and wouldn't it also have been there when he got his PC?

Sorry for the late response but I built my PC in December 2017 so about a year and a half. Here's my build if you want to take a look at it: https://pcpartpicker.com/b/4mFtt6

i would say, do what the other dude recommended unplug one fan and then run the build, if it still rattles then try unplugging a different fan, it should throttle/shutdown if it gets too hot

Common sources of coil whine are from PSUs and graphics cards, though other components can certainly be responsible.

If you have a discrete graphics card, try using your system's integrated graphics (if possible), and see how it performs both idle and under load.

Post your part list for some more specific suggestions.

If a physical bump interrupts the buzzing, it's also possible that the sound you are hearing is not coil whine. (I wouldn't recommend continuing to do that, especially if your build relies on HDDs.)

It could be a failing fan, the one on my S340 was making a rattling sound and NZXT sent me a new one. Try unplugging one of your fans and see if it still happens.
