There are a couple ways of doing this. The first way is to right click my computer, then click on properties then click on the Device Manager tab. Once in the Device Manager section, expand the link by Display Adapters, here you will find out the brand video card you have installed on your machine. The second way to find out what kind of video card is installed on your system, is to click on the start button, click on run, once in run type DXDIAG. You will then need to click on the DISPLAY tab and the name and manufacturer of your video card will be displayed.
