How to solve the graphics card running normal lol but not open?

Why does the display of the video card in Device Manager work correctly, and still show "DirectX Error" When you open the League of Legends (pictured below)? The reason is not that the video card driver is too old in the window, but the graphics driver is "too new". This article will explain its causes and solutions in detail.

As Microsoft has stopped maintaining its XP system, Nvidia officials are no longer WHQL to sign up for the graphics drivers under the XP system. Therefore, when the XP system is installed with a too new video card driver, the DirectX feature will not work properly because the files in the graphics driver are not digitally signed. Specific reasons can be seen from the description of the DirectX Diagnostics tool (pictured below).

1, Landing fast Technology (original drive home) drive download channel, download a October 2013 Nvidia graphics driver (before the driver has passed the WHQL test). Do not install after downloading.

2, in the "Add or Remove Programs" in the Control Panel uninstall the Nvidia graphics driver and all components (as shown below), and restart the computer as prompted.

3, restart the computer after the installation has just been downloaded from the fast technology driver download channel NVIDIA graphics driver, and restart the computer as prompted.

4, restart the computer after the DirectX function can be restored to normal (pictured below). LOL will also be opened normally.
