2. On the Start menu, click Run.
3. In the Open box, type "dxdiag" (without the quotation marks), and then click OK.
4. The DirectX Diagnostic Tool opens. Click the Display tab.
5. On the Display tab, information about your graphics card is shown in the Device section. You can see the name of your card, as well as how much video memory it has.
