You computer is old enough that I don't want to recommend a video card. It is difficult to know which ones will work. I suggest that you choose a manufacturer and contact their Tech Support for help with choosing the best card for your system. The sellers pay for shippuing the card to you, but you pay to return the card if it doesn't work.
