The driver signatures of 1 and Win7 systems are different from XP and can only be started in group policy. First, open the "Run" program in the "Start" menu, and enter the gpedit.msc command in the run window to confirm the entry into the group policy interface.
2. in the group policy editor window, first in the directory on the left, find and open the user configuration->; Manage templates-> System->; Driver installation ",and then in the right window of driver installation, find the item" Device-Driven code signing ",and double-click to enter its properties.
3. After entering the code signing window of the device driver, the settings here are also different from XP. First, set whether to use driver signature. If so, you must select the Enable option, which must be checked.
4. After enabling driver signing, you need to set which method to enable, whether to ignore, warn or block. Needless to say, it is "warning". Only when you start the machine will it pop up a blocking window. After setting, press "Apply" and "OK" to save and exit.
Next, uninstall the driver of the graphics card in safe mode, and then restart the computer to enter the Windows system. Pop-up window, select "Stop Installation", and then update the driver yourself.
