Now, this one is weird: TT games make my computer whine?

[Zappanale]

Hi, here's a weird one.
TT games play great on my pc- I'm playing puzzle agent now. Here's the thing: Whenever I do, my PC makes a weird whining sound. It's not from the speakers- Set them to mute and it still goes. Minimize or otherwise click out of the game (say to go to a web browser) and it stops, only to start again when you go back to the game.

I know this sounds like the only possible answer is aliens, or maybe magnets, but I swear this is a real thing.

Here's my PC specs...
W7 home premium 64 bit
gtx 570
intel i5 2500 k
8 gigs ram

Any ideas? Ta

That's not an entirely unknown technical phenomenon. Some hardware parts can make noise under certain load conditions.
Here's a video of a graphics card (http://youtu.be/_pIWPCw3UVc) for example.

Does it sound anything like that?

Yeah, quite a lot like that. Which is weird, since it's unique to Tell tale games!

I don't really know how to help you with that.
The best thing you can try is narrowing down which hardware component causes it, and, if possible, RMA it.

EDIT:
Enabling VSync in the graphics driver is supposed to work as a workaround, if it's the graphics card.
