Computer buzzing when in game

[Coolnick154]

Often When I play games on my new computer (i built it myself) there is a buzzing sound coming out of the headphones, even if i plug it into the motherboard or the headphone jack on top it buzzes, any ideas about what I should do?

Update video drivers? Could just be the quality of the built-in audio in the motherboard.
