  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

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.
