You might have overlooked installing the cd that came with the motherboard.
What you probably have is an IRQ conflict.
Pull all the cards except the video and install the motherboard drivers, then the video drivers and then put the other cards in one at a time and install the software for each.
That Compro VideoMate TV Ultra card goes next to the video card ( if its what I think it is). Install that second after the video card.
Hope this helps
