Two solutions that are not installed on the graphics driver

Video card driver is a bridge between the video card and the computer, if the video card driver is damaged, the video card can not be properly coordinated with the computer, such as a flower screen phenomenon, the resolution becomes smaller or larger, and can not adjust, or appear black screen phenomenon.

If the graphics card driver is damaged, it is necessary to update, there are two methods of updating:

The first is manual update, from the Device Manager, right click on the video card device, select Update in the pop-up menu, or to the control Panel, find the "Add Hardware" item, double-click, eject the Hardware Installation wizard window, and then select the hardware to install the driver, then find your driver (driver can be downloaded to the Internet , or it could have been originally backed up).

The second method is to use software to update, such as Drive Wizard, drive life and so on, easy to use, open the program, click Detect, if detected to update the hardware, click Update can be.

But sometimes found that the video card (also including the network card) driver update, when using the above method to update, and display has been successfully updated, and then power on, the computer screen still appear original damage phenomenon, how to update the update is not successful, you update how many times, again boot, is still a corruption phenomenon. This situation, how to solve it, I will teach you a personal experience and discover an update method, and in this way to help countless people to solve the problem. If you're having problems with a video card (or a network card) that doesn't have a driver installed, you might as well try this method.

This article is taking the Win7 system as an example to explain how to successfully install the graphics card driver method.

Enable driver signing (for Win7 systems):

1, enable driver signing, is the first step to successfully install the graphics driver, because only the driver signed, to prevent the system to automatically install the driver, can rob the system automatically install the driver for you before the successful installation of the graphics driver, or the system always install the damaged driver for you, will appear countless times the installation is not successful.

To enable the driver signing feature, in the Win7 system's desktop "start", open "All Programs" in the "Run" program, in the pop-up running window enter "Gpedit.msc", and then press "OK".

2. Pop up the Local Group Policy Editor window, and in the tree directory on the left side of the window, find the "Manage template" option under "User Configuration" and select this.

3. Then, under "Manage Templates", locate the "System" item and select this.

4. Next under "System", locate the "Driver installation" item, select it, and then choose "Code Signing for device driver" in the right-hand window.

5. In the "Code signing for device Driver" window, perform three steps:

1) in the 1th place, select "Enabled".

3) in the 3rd place, first press "Apply", then press "OK" button, this must press, otherwise the setting is invalid.

Restart your computer, press F8 to enter Safe mode, remove the old graphics driver in Device Manager, and exit Safe Mode when you are finished.

6, restart the computer, normal access to the WINDOWS7 system, then, will pop up a warning prompt box, ask whether to block unsigned driver installation, this is the most critical place, of course, to prevent, only to prevent the system automatically installed for the computer graphics driver, we have the opportunity to update the driver we want, Only then, the driver of the video card can be updated successfully, so press the "Stop Installation" button.

The next step is to update the driver for your video card, either manually or with the Driver wizard, which you have decided.

Tip: After the driver signature is set, if the Block window fails to appear, you can reset the driver signature, set it to "Not Configured", press "Apply" and "OK", exit Group Policy, then go to Group Policy, reset to "enabled" and "warning", and then press "Apply" and "OK". Why bother, actually this is to activate, let the system re-remember your new settings, this is a good way to solve the blocking window can not pop up.

7, the above is the Win7 system to enable the driver signature function, but the XP system is not the same as the Win7, if you are an XP system, so do, my computer, right-click the "Driver Signature" button, set to "warning", then "OK" You can do it. Of course it can be set in Group Policy, but I prefer this method.

If you want to see the XP specific setup process, the "video driver installation is not on" This term Baidu, you can find on the internet I wrote another article on how XP system to enable driver signing.

　Precautions:

1, some Win7 system at the beginning of all programs do not run this item, find the "Run" Method: right mouse click the "Start" button, select "Properties", press "Customize" button, in the "Run Command" before the selection box tick, press "OK" exit.

2, set the program signature, in Safe mode after removing the graphics driver, when re-enter the Windows system, be sure to select block, so that the driver can be successfully installed manually.
