Lenovo IdeaCentre Q190 Video Card
A graphics card computes and sends the resulting images to an external monitor where it is displayed for you. Today, graphics card maker nVidia is the most popular in the dedicated video card market, while AMD is sitting in second place. Integrated video cards are almost never as good as a dedicated video card, generally speaking. Almost all newer desktops will have at least one spot available for a video card to be installed on the motherboard. There are really only two kinds of graphic cards, integrated and dedicated. An integrated graphic card is built-in to the main board, while a dedicated graphics card is an individual piece of hardware that is bought and installed separately. A dedicated graphics card is usually necessary for high-end games on the desktop like Overwatch, Battlefield or Far Cry.
What symptoms are present when the graphics card really needs to be replaced?
- The graphics on your screen depicts lines
- The computer reboots when beginning a game
- The display does not turn on when starting the computer
- A driver for the video card cannot install fully
