I wasn't sure which forum to put this in so I hope it's in the right one. I have a friend who has a HP dx2200 desktop computer. It has a built-in VGA card. He wanted to use two monitors so he put in a PCI (or PCI Express card, can't remember which) but it's not working. The only card the system sees is the built-in card. He's not getting any error messages or anything. Going into Device Manager shows that the system sees only the built-in graphics card and nothing else. He's done this on several other computer's, though none of them have been dx2200's, and hasn't had this problem so this is a new one. Any thoughts?
