Checking the graphics card on a computer running Windows Vista is a relatively simple process. There are a few different ways to do this, but the most common is to use the DirectX Diagnostic Tool (DXDiag). To open DXDiag, press the Windows key + R, type “dxdiag” into the Run dialog box, and then click OK.
Once DXDiag has opened, click on the “Display” tab. This will show you information about your graphics card, including the name, manufacturer, and driver version. You can also use DXDiag to test your graphics card by clicking on the “Test” button. This will run a series of tests to check the performance of your graphics card.
