  11. Working with Drivers • Video drivers work same way as other hardware drivers • Can access this screen from Device Manager or Device applet • Update driver • Roll back driver • Uninstall driver

  12. 3-D Video Cards • Graphics processing units needed • Screens redrawn several times per second • Need to covert data to coordinate and color • 3-D video cards have massive amounts of RAM for textures and fast processors for transformations

  14. Video Card Problems • Vast majority of problems are • Improper or corrupt drivers • Incorrect settings very large refreshing rate • Incompatible or corrupt driver symptoms • 640 x 480 mode • 16-color VGA • Your response • Boot into Safe mode and remove driver • Use Add/Remove Programs if available • Use Device Manager
