Ok, so all last week i worked my ass off to earn the money to buy COD 4 and i went and bought the game yesterday. And it said something about the video card doesn't support alpha blending. And ALL lastnight i tried to download the newest version of NVIDIA and i JUST not woke up. It was done downloading, BUT THE STUPID THING WASN'T A VERIFIED FILE! So i tried to run it then it started actually installing it so i figured it would work and it said the same thing about the file not being verified and closed every thing down. Is a video card something i have to go out and buy and put into my computer or can i download it and where? If you can download it (and it actually working) PLEASE SEND ME THE LINK.
