Start by identifying the missing/corrupted driver:

1. Check your Device Manager
2. Look in the programs/applications list to identify the device you need a driver for
3. Drivers are often found on manufacturer’s websites or device product pages
4. If a driver is missing, you may be able to use a generic driver
5. Compare your device driver version with the latest version of the driver to confirm it is the correct one
6. Install the driver on your laptop
7. Reboot your laptop to see if your driver is present and the device works properly
