I just finished building my PC like a week ago. I just noticed there is a faint buzzing noise while playing a game (the noise also comes out from my speakers). I tried to pinpoint the noise and turns out it's coming from inside my computer.
The buzzing noise sounds like it's coming from either power supply or graphic card. I'm assuming it's the graphic card, because the power supply is already making a noise (like a hard disk. I searched a little, and it's a common problem for XFX Pro750w Core edition).
There is also another issue; when I turn off/on the power supply (switch), I hear a bump noise from my speakers.
I don't mind the noise but I want to make sure it is not something bad. Is it safe to ignore it?
I've uploaded the sound file which you can hear the noise (when I start a game): http://www.mediafire.com/download/njgxdb7qbkrmaxb/2.wma (There are 2 sounds: power supply and graphic card. The power supply's noise sounds like a hard disk, while the graphic card sounds buzzing.)
Thanks in advance...
