Hi everyone-I've had the same problem with two different computers. (I know, I should never get onboard video. I won't make the mistake a third time.) I have onboard video and I can't get my monitor to even come on when the AGP card is in the slot. Even If I plug the monitor into the onboard video, there is no display as long as the card is in the computer. I've tried different cards too...no problem with PCI cards, but the AGP just won't even recognize the monitor. Any help would be appreciated. Thank you.
