How to Update Device Drivers
Most PC et portable owners know they need to periodically update their operating system logiciels, security programs and so on. However, fewer computer users know how to update their device drivers-or even why drivers are so valuable.
In plain terms, a driver is software that enables the vital communication between your PC’s operating system and each internal or external device—from graphics cards and DVD drives to microphones, webcams and printers. If your drivers aren't up to date, your computer may lose the ability to "speak" to these devices, rendering them useless.
Security updates and bug fixes are often updated automatically, but driver updates may not be so simple. For this reason, it's a good idea to occasionally check and update your drivers manually-to ensure they're always up to date.
One simple method to update drivers in Windows 7 or Windows 8 is to navigate to Check for Updates in your Control Panel (under the Security heading). You can access the Control Panel from the Start menu. Check for any updates that may apply, then view and install them. A restart may be required, so be sure to save all work and close any open applications before you begin.

How to update graphics drivers
Updating graphics drivers entails a slightly different process than that described above, since in many cases, you must download the driver update from the manufacturer of your graphics card – not the company that built your portable ou desktop computer or supplied the operating system.
To determine the make and model of your graphics card, go to the Start menu and search for "device manager." When a shortcut for the Device Manager appears within the search results, click on it. In Windows 10, you can access the Device Manager by navigating to Windows System -> Control Panel -> Hardware and Sound -> Devices and Printers.
Once you are inside the Device Manager interface, you should see your computer's various devices listed. These may include battery (if using a laptop), computer, disc drive, display adapters, DVD/CD-ROM drive, clavier, and more. The option you are looking for is "display adapters."
When you click on this option, it should expand to show your graphics card or cards. If you right-click on the graphics card listed, you’ll be presented with two options: Search automatically for updated driver software and Browse my computer for driver software. If there is a new driver available but Windows is unable to locate it, you can visit the manufacturer's website and search by the make and model of your graphics card to check for available driver updates.

Téléchargez les mises à jour applicables et installez-les pour terminer le processus de mise à jour. In some cases, the manufacturer's site will offer an option to automatically detect and install the latest driver.
