Just like all other hardware devices, your motherboard requires drivers to work correctly. If you haven’t done so in a while, you should check whether you’re using the latest chipset drivers available by going to the official website of the manufacturer of your motherboard. If a newer chipset driver is available, download it to your computer and install it just like any other driver.

We strongly recommend you avoid various third-party driver finders and driver updaters because many of them are scammy and some are even downright dangerous. The only driver update we can recommend is Intel Driver & Support Assistant.
