Second monitor stuttering while in game

SyphonBlue

I just upgraded my computer to an Asus P8Z77-V motherboard, i5-3570k and a Geforce GTX 660. Everything runs great, except when I'm in a game. When I open a game, the rest of the computer runs into a horrible stuttering problem. Basically, when a game is open (I should clarify, it is only when the game is running fullscreen; if I window the game, everything runs normal) the stuff on the second monitor begins updating very slowly. It's only video, the audio runs perfectly fine. I've tried a different video card and am running in to the same problem. I have not tried going back to the old motherboard yet. Any help?

I would just disable the 2nd monitor while gaming. (Win+P to swap display modes quickly if you're running Win7/8) I've had nothing but issues when trying to sort out multiple display setups when running fullscreen applications.

Well the problem is I like to watch videos on the second screen while playing a game.

have you tried disabling aero while your running a game?

find the main .exe for the game, and then right click on it, under properties go to compatibility, check mark the box named "disable desktop composition"

Running Windows 8, don't have that option.
