If you are unsure of whether or not you need to update your Drivers, or indeed which Drivers may need to be updated, you can run a Drivers scan using a driver update tool (you will need to pay to register this tool but usually the Drivers scan is free).

Once you have the details you can search the manufacturers website for your drivers and, if available, download and install these drivers.
