Outdated drivers can sometimes cause conflicts. Visit the manufacturer's website for your computer or components and download the latest drivers. You can also use a driver updater tool such as Driver Booster.

If none of these solutions resolve the issue, you may need to seek further assistance from Microsoft support or a qualified technician.
