A device driver must be reinstalled

1.Remove any discs from the optical drive.

2.Select Start > Control Panel > System and Security > Device Manager.

3.In the Device Manager window, click the plus sign (+) next to the type of driver you want to uninstall and reinstall (for example, DVD/CD-ROMs, Modems, and so on), unless a minus sign (-) is already showing.

4.Right-click the device listing and click Uninstall. When prompted, confirm that you want to delete the device, but do not restart the computer. Repeat for any other drivers you want to delete.

5.In the Device Manager window, click Action, and then click Scan for hardware changes. Windows scans your system for installed hardware and installs default drivers for anything requiring drivers.
