I assume you're referring to FF8, since there is no GeForce patch for FF7 (FF7 has a TNT-patch, FF8 a GeForce patch).
If you're game isn't running, there could be a variety of reasons. This is what you should do.
1. Click on Start and then on Run.
2. Type in "dxdiag" and hit enter. It will bring up the DirectX Diagnostic window.
3. There is a button marked "Save All Information..." Click on it.
4. Save the file on your desktop.
5. Close the DirectX Diagnostic Window.
6. Open up the file you saved on your desktop by double clicking on it.
7. Copy in information in the text file and post it up on the board.
That should be enough for us to start off with.
