X3100/GMA965 Graphics Driver Update...help

I'm starting to go crazy. I ordered a used Dell Latitude 630 off of ebay. It works fine, it's fast, it's all good...except I wanna update the graphics card so i can do a few more things. I have been trying for days and for the life of me I can't get this to work.

When I go to the downnload center I choose the

Product Family: Graphics

Product Line: Laptop Graphics Controller

Product Name: Mobile Intel® 965 Express Chipset Family

OS: Windows 7 Enterprise 64 bit version

Download Type: Drivers

Then I usually choose exe and if I run it I get a message telling me that "This computer does not meet the minimum requirements for installing this software"

if I choose to save the exe files and unzip them and go through installing manually wit the "have disk" option, I get a message that says

Windows encountered a problem installing the driver software to your device

Windows found driver software for your device but encountered problems while trying to

install it.

               Mobile Intel(R) 965 Express Chipset Family

The driver selected for this device does not support this version of windows.

It doesn't make any sense. And it's really really annoying, please help.
