Hi, I think somemore info is needed for some of your problems but yes it is a 3d card but a cut down version of a more powerfull card, LE after any gforce card means its not very good for games in my experiance im afraid. As for the other problems, Did you have another card installed before it? Or even onboard graphics? If you did and did not get rid of the other drivers then this might be your problem. Im sure there is someone out there that will have a better idea but more info is needed.
