To open the Device Manager:
Open your Start menu, in the search field type Device Manager and click the Device Manager shortcut.
(If you are using Windows 8, press the Windows key, type Device Manager at the Start screen, select the Settings category, and click the Device Manager shortcut.)
In the device manager you can check in the category of display adapters to see what version of drivers you have loaded for your graphics card.
