Graphics card question. 10 pts of course.?

What kind of computer is it? If its a laptop you can't change the graphics card. If its a desk top what is the make and model? It makes a difference as to what the specs of it and the mother board are as to what kind of card will fit. Also what operating system are you using and how old is the game? It could be a conflict between the game and vista or windows 7. To find out go to the game manufacturers web site and see if there are any known compatibility issues like maybe a patch so that it will run.
