On XP right click on My Computer, select properties. Go to hardware. Select Device manager. Go to display adaptors and doubleclick on it. When it opens it will tell you the graphics card you have.

The drivers you need depend on what card and OS you're running, so report back on that as well.

On XP My Computer may be in the start menu or on the desktop, depends on your setup. It doesn't matter where you find it.

The radio will only be found in the game, not in the Controllers section of the Control Panel, so don't worry about not seeing it there.
