Tech Tip: If you are having trouble deciding which is the right driver, try the ASUS Driver Update Utility. It is a software utility which automatically finds and downloads the right driver.
To find the newest driver, you may need to visit the ASUS website. Most major device manufacturers update their drivers regularly.
After downloading your new driver, it's time to install it. For Windows users, the built-in Device Manager is your go-to tool for managing system devices and drivers. Here's how to use it:
Right-click the Start button to open the Quick Access menu.
Select "Device Manager" from the list of options.
In the Device Manager window, locate the device that needs updating.
Right-click on the device name and choose "Update driver" from the context menu.
Follow the on-screen instructions to complete the installation process.
Once the installation is complete, restart your computer to ensure the new driver is properly integrated and functional.
This simple process helps keep your system running smoothly and maintains compatibility with your hardware components.
Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.
For more help, visit our Driver Support Page for step-by-step videos on how to install drivers for every file type.
