I bought an Nvidia 6200. It came with drivers on a disk, but I have win7, and it only supported Vista and XP, so I went on the site, and downloaded new ones that work on win7, but they won't install unless the card is in. I install the card, and I have graphics until Windows starts. Then I have nothing. I need the drivers to get the picture, but I need the picture to install the drivers? What do I do?
