Hello,I should start by saying I know very little about computers and Im running an old dell dimension 3000. A few months back I took my machine to the geek squad to have them put in a graphics card and have seen little or no difference. GeForce 8400 Gs-pci is what I bought. Lately Ive been doing some research and toying with the idea of building my own machine to learn more. While doing so Ive discovered my device manager shows that the Intel 82865G graphics controller is enabled - I believe this is the onboard video that came with system; and that the Nvidia card is also enabled. Can I just disable the Intel onboard and restart since the new card and drivers are already installed? Ive read that you need to plug new card directly into monitor to set up but I believe this has already been done. I dont want to mess anything up, and Im not sure that I have the know-how to do this either. Any help would be greatly appreciated. Thanks
