High Pitched Buzzing Sound While Playing!

[Arnold]

I bought the New Vegas (Ultimate Edition) yesterday and after installing the game I started playing. At first there was no problem at all but from nowhere it appeared. I wear headphones and suddenly a high pitched buzzing sound appears from nowhere and it just increases and then goes away. This keeps happening every 30-60 second. I haven't been able to find a solution, is this a known issue, if so... please help!

Hmm you could find out where is the sound comes from, but im guessing its either from your power supply or graphic card.

Normally if your fps is high, your graphic tend to cause that buzzing sound.

I know this because this happens to me in any game that my fps exceed above 60.
I have a GTX 670.

There is no fix for the buzzing sound unless you activate VSYNC to limit the fps.

Oh man. It's not coming from the PC itself it's coming through my headphones or is that what you meant? That cannot be the problem since the ♥♥♥♥♥♥♥ sound will start when I CTRL+TAB the game down also. It's so ♥♥♥♥♥♥♥ anoyinng!
