Hi, I have a p3 733 compaq sff with a riva tnt2 pro onboard. However when i try to install my hercules 3d prophet 2 mx when the computer boots up the screen remains black, and there is a little click when it should be acknowledging the card. After when i return to the onboard card it tells me there was a problem with an add-in card and safepost is skipping any add-in cards for the next boot. I have no idea what to do or if the card can even be salvaged, it used to work. If anyone could provide any help i would appreciate it sooooo much. Thank you
