OK, I think I know what the problem is - my video card only has a DVI output and when the card is installed it defaults to this instead of the VGA connection on the motherboard that I have been using. I think a DVI-VGA converter would do the trick but I'm wondering if there is a way to install the video card but still use the VGA connector off the motherboard. Any help would be great. Thanks!
This is the card:
