Installing a new graphics card.

If you've been able to live with a 64MB Video Card, I know you're not going to be expecting too much so buying the card Yoorah has linked is going to work out fine for you. Heck, anything with at least 256MB is going to work find for you. Installing a graphics card is already really easy. I'm lazy, so I'll just point you over to a video that guides you through the process. If you don't like the video, just hop onto Youtube and search 'How to install Graphics Card' and you'll get tons of results.

Good luck.
