Update Graphics Card Drivers

Why is it important to keep your video drivers up to date?

Video card drivers (software that interfaces with your graphics card) often include vital bug fixes and/or optimizations. Your card is generally shipped with a driver pre-packaged, but this driver is usually out of date by the time it reaches your computer. One of the most important steps you can perform when installing a new video card or using a new computer is installing the most up-to-date driver.
The update process will vary depending on the specific video card you have, but many players will find that they likely own a card from one of three major product lines: NVIDIA, AMD or Intel. Since these are the most common types of graphics cards, we will cover the basic update process for each.

How to identify your graphic cards?

League Of Legends Client Constantly Crashing

Press [Windows Key] + R (this will open up a 'Run' window).
Type dxdiag and then hit Enter.
Select the Display tab.
Note the name and manufacturer of your card in the top left corner of the window.

Most common graphics card manufacturers have a solution that scans your computer and updates drivers automatically. We recommend you to manually download the drivers at the sites below:
AMD
NVIDIA
Intel

Update DirectX

Updating your DIRECTX

DirectX is a set of Application Programming Interfaces (APIs) developed by Microsoft. This API allows various applications to interact with hardware on your computer without knowing ahead of time what that hardware is. Many applications use DirectX, however it is most commonly used in running games, because they tend to be hardware intensive.

What does it mean to me?

If you are using an outdated version of DirectX, League of Legends is going to have problems interacting with your hardware (your graphics card, mouse, keyboard, speakers, etc.). This can result in a variety of errors, ranging from driver crashes, keyboard or mouse inputs failing to register, or sound cutting out.

Please keep in mind that the highest version of DirectX that you can get depends on your version of Windows, as described in the above Microsoft article.

Note: Windows XP is no longer supported by Microsoft as of April 8, 2014. That means that if you cannot get the appropriate version of DirectX from the above link, you will need to upgrade your Operating System. You can find more info here: http://windows.microsoft.com/en-us/w..d-support-help

Update your version of Windows

Make sure your Windows is fully updated

Windows updates often address issues within the Operating System and DirectX, which may lead to application crashes. You can find the relevant instructions from Microsoft here:

Perform a clean boot on Windows

Clean Boot Guide

Sometimes, other applications, especially software that uses an overlay (i.e. Skype, Teamspeak, Steam), can cause League of Legends to crash. You can exit or disable those applications and see if this resolves the issue with crashing by trying out a custom game in League of Legends.
Alternatively, if you want to be 100% sure that no other application is interfering with League of Legends, you should try performing a clean boot in Windows. To do so, please follow the instructions below:

Disabling all non-essential processes:

Press [Windows Key] + R
Type msconfig into the text bar at the bottom of the menu
Click on the Services tab
Check Hide all Microsoft services so you don't end up accidentally disabling a key process
Click the Disable All button
Click on the Startup tab
Click on the Disable All button
Click on the Apply button
Click on the OK button
Restart your computer

Note: For performing a clean boot on Windows 8 and 8.1 please see the following Microsoft article:http://support.microsoft.com/kb/929135

Reset your Graphics Card software

Make sure your Graphics Card software isn't interfering with League of Legends

NVIDIA comes with the NVIDIA Control Panel and AMD comes with the Catalyst Control Center. Both of these programs allow users to set up graphics profiles that can override application settings and sometimes interfere with League of Legends as a result. Re
