Locate the name of the manufacturer of the circuitry of your video card, or chipset, by utilizing the device manager on your Windows 7-based computer. A video card's job is to render and subsequently display images for video and game applications on your PC. Also, many video games have minimum requirements of which chipset is needed for you to play them. The two major creators of video card chipsets are Nvidia and ATI, and your chipset is one of these names followed by a model number. In general, the higher model numbers correspond to more recently produced chipsets.
