To get the information you require:

OS info: Press and hold the Windows key (the key between the CTRL and ALT Keys that has the Flying Windows logo on it) and the press and release the Pause Break key. This will bring up the info on your Windows OS with some other details but not your Graphics Card info.

Graphics Card info: On the top left side of the System Info page (Windows key + Pause Break as described above), you should see a list that includes Device Manager, click on it. A new window opens and from the list in that, expand the Display adapters and it will show you what you Graphics Card is.
