i don't really understand and i don't know what window it is i'm only 12 years old
all i know is the my driver is a
NVIDIA GeForce 7600 GT
That's the kind of graphics card you have. The drivers are the software that your Operating System (windows in this case) uses to communicate with the graphics card. The error is telling me that your graphics card doesn't support a very simple standard graphics feature.
I'm not too familiar with Windows 7, but you can try this:
Right click somewhere blank on your desktop.
There should be an "nVidia Control Panel" option in there... if so then click it.
This will bring up the NVIDIA Control Panel. In the lower left at the very bottom of the window is a link "System Information".
On the top of the "Details" is a "Driver Version". Post back and tell me what that says.
The window will look something like this:

Edit: Added the "click" as Ben suggested... oops.
