Cod4 Problems

Hey guys i just got my cod4 disk and im pretty pissed off that it dosent work. It says that my "video card or driver dosent support UBYTE4N vertex data."
So i really i want to hack cuz this site is teh best for hacks, and i need help. So please comment below on another way to play it.

buy a Graphics Card that not integrated on your motherboard

Also if your RAM has not enough memory buy one with 4gb memory!

Man just google it and you will found the fix , lol .
