Help with updating my video card drivers?

I need to update my video card drivers and don't know where to start. Here is some info.

I have windows XP

I have a Dell Latitude D610

I do not have an intel video card driver so I cannot determine my video card driver type by right-clicking the desktop

I actually just got a new driver because I completelt restarted my system and I got it from the dell support so I do not know why I need to update them.

I need them updated for a video game called minecraft

Any info will help.|||find out what kind of graphics card you have with a program like everest. then go to the homepage of the company who produces that card and download the latest drivers for it there.
