Replacing a video card is easy if it is not built-in into the mother board. If you have your own cheap then buy a video card that is compatible with your pc model and there you go. However, if a video is on board or built-in into the motherboard, you would need a new mother board if there is no more slot available in your computer to plug in that video card. If you don't know how to replace it,better see a computer hardware service man to do the work for you.
