Question about my video card in my laptop?

I have upgraded my computer from windows vista to windows 7 evaluation version. And i don't know as much as i wish about computers and troubleshooting and that's why i'm here. but i know i have an upgrade graphics card and am not really sure how to access it on my laptop. right now its running through the Standard VGA Graphics Adapter and before i upgraded to 7 it was going through the other video card. if you have any suggestions please let me know!! Thanks!|||Your probably need a driver. Since Windows 7 is not officially released, the computer manufacturer or the video card manufacturer may not have a driver for it. Check their site(s) though.
