Can I update my Dell Xp's Video Card for Free and Without Doing anything but Downloading?

I was wondering is there anysites I can download aan update from or is that the way it works?|||just go to the dell site and go to the support page and find the drivers for your model.it's all free.|||You can update the drivers for free off Dell's support site, but that won't upgrade its capabilities; otherwise no, you can't upgrade your hardware for free (or paid) by downloading an application.
