I believe the conversation when the wrong path when I was trying to correct information.
I did not tell him to go into BIOS, I was correcting information:
You disable onboard video card through BIOS, if you do not have this setting your onboard video might yield to the new video-card, (the link was to help look for jumper settings to disable onboard for certain EMACHINES) or there might be jumper settings.
I never typed that all motherboards have the option to disable through BIOS.
Of course we should wait for his model.
