Hey, so I recently bought a new motherboard(dont remember the kind off the top of my head but I can dig out the box if it's needed) and a graphics card(GeForce 8400GS). After I installed all the drivers for the motherboard I installed the video card. It works fine for the most part except that in games its really laggy even on the lowest settings. My friend helped me diagnose this problem and we found out that the onboard video card(ATI Radeon HD 3300) doesnt like another graphics card in my computer.
To fix it I just took out the GeForce card and the game runs great. Plus theres no yellow !(that yellow triangle error thing) in device manager anymore. Is there a way I can get around this problem? Like disable the onboard card?
Oh yeah, I updated all the drivers too if that matters.
