What should I do if the driver update fails?

Failed to update the driver, the system will be unusable or the system file will be destroyed. The solution in the Windows operating system is as follows:

One is to reinstall the old version of the driver. If you can get into Windows, then it is recommended to re-install the old version of the driver to give it a try, generally solve the problem.

The second is to restore the old version of the driver. Windows XP provides a feature to restore older drivers, click the "Back to Driver" button. However, this method is limited to the drivers that passed the test.

The third is to reinstall the hardware. This requires opening the chassis, first unplug the graphics card, sound card, network card and other hardware devices from the motherboard, then re-plug, restart, and install the driver. Of course, what is said here is also the old version of the driver.

Four is reinstalling the system. If the above methods do not work, then you can only reinstall the Windows operating system.
