I won an old Dell Optiplex GX260 Desktop. I want to upgrade for my mother-in-law but have some problems. I have installed Window 7 but now I get a message "Video Driver Card must be more than 64mb". When I try to play Solitare I get another message:

"Hardware acceleration is either disabled or not supported by your video card driver, which could slow game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on."

What kind of card and/or driver do I need to get?
