In the first place, you can use the hard id to find the driver for Windows 10 unknown device. In some conditions, maybe you can’t find the device name, so you are unable to find the unknown device driver from the official site or from the Internet. Find the device driver using the Hardware ID Open Device Manager by pressing the Windows key on your keyboard and typing Device Manager, then open the result. You will be presented with a list of devices attached to your system, and you will notice the Unknown Device with a yellow exclamation mark.
This issue is caused when Microsoft Windows does not properly detect the chipset or videodisplay.
Download and install the latest chipset and video card drivers. If you or someone you know built your computer, it came with the motherboard CD. This CD contains the chipset drivers. Otherwise, you can find drivers for all the major chipsets on our motherboard drivers page.
If installing the latest chipset or motherboard drivers doesn't resolve your issue, make sure you have the latest drivers installed for your video card. For a listing of video card drivers, see our video card drivers page.
If you tried the above two steps and your Windows Device Manager still contains an Unknown PCI device, likely the device cannot be identified.
If you that the device not being identified is installed, we suggest you obtain the latest drivers for that device. A listing of drivers is on our drivers page.
If you have recently finished installing or reinstalling Windows onto the computer and are getting the unknown PCI device, we suggest you manually identify the PCI device through the registry.
