Im putting a PNY GeForce 9400 GT video card in my brothers gateway computer. He is currently using onboard video. I was wondering if i need to disable the onboard graphics before i put the video card in. He would like to have both both enabled so he can use one for a TV and one for the monitor. If I need to disable onboard graphics, i was wondering how exactly to do that. (im guessing it involves the bios). Thanks in advance.
