Download the driver here first:

Then in Device manage, right click on the device to uninstall it. But make sure you click "delete driver from system" before proceeding. Then hit Ok.
Then install the new driver on your system and your device should be found again with the new proper driver.
FYI, you should never use default windows drivers. Windows will find a close driver, but sometimes it's buggy because it's not the actual driver for your hardware. When building a PC, you should go to your motherboard manufacturer's website and download all the latest drivers for your system and install them.
