"Can't go to Dell"? If you hate Dell so much, why do you use one of their machines? :p

Never said I hate dell.
This is a very site to learn.
Actually its all in the challenge of getting this thing running.

Hum. Well, why not go to www.dell.com, support, downloads and search for the downloads for your laptop model/service tag?
