I believe there will be some friends in the installation of graphics drivers will be installed failure and so on, I have a way here to give everyone a try, do not guarantee that will succeed, after all, the cause of the problem will be different, we can go to try. My overall approach is to transfer the installation driver.
1, open the Device Manager, to find the device is not installed drive.
2, click the right button, select the Update driver, we choose to browse the computer to find the driver.
3, the next interface we choose to get from the list of device drivers on the computer.
4, find the appropriate equipment, click Next.
5, choose to install from the disk.
6. Select the path of the driver that was previously downloaded and click OK.
7, click Next.
8, the equipment installs the drive automatically, waits for the equipment installation completes.
