Intel 4 Chipset not working...Does not support my version of windows.

Hello Everyone. I'm new here, and I've been trying at this "Graphics" stuff for about a week now, reading forum after forum, and visiting link after link. I wanted to play a game, but the OpenGL was only version 1.4, and required 2.0 . After tons of research, I realized that I needed to update my drivers. I tried using NVidia, and after tons and tons of errors, that didn't work...After more research, I figured out that my Display Adapters is Intel G33/G31 Express Chipset Family.... so I tried downloading an Intel Media Accelerator, which would give me OpenGL 2.0, but when I tried to use Setup.exe, I would get "This computer does not meet the minimum requirements for installing the software", so after MORE research, I tried to use Device Manager>Display adapters>Upgrade Driver Software>Install Manually>Let Me pick>Have Disk> and then i used the ".inf folder". But then it says, "The driver selected for this device does not support this version of windows"......So, needless to say...I'm stuck....My computer is Windows 7 Home Premium x64. My Vendor I.D. is 0x8086 and my Device I.D. is 0x29C2....what can I do to make this work? Is there something I have to buy? I hope someone can help because I've been at this for a while.
