I have problem with a graphics card. I don't know much about computers. My daughter recieved Zoo Tycoon 2 for her birthday. Anyway the man at Best Buy said that the card would work in my computer. I put it in and rebooted it and now I have a black screen. I disabled the graphics already in the computer just like it said to do. I am sure that it is installed correctly and I hooked the moniter up to it also. Any advice would be greatly appreciated. Thanks.... :)
