No, not a laptop, and I can't imagine it was a fan, it was so high pitched it was painful to listen to.

Uh, thanks, I guess.

I downloaded the demo of Geneforge yesterday and have been enjoying it a lot. However, while I was playing it earlier, my computer started letting out an incredibly annoying high pitched squeal. I know it isn't coming from the speakers, as turning them off doesn't stop the squealing, and I know it has to be the game, since exiting the game did stop the squeal. Any ideas on why this is happening?
