Look up the make and model of your DVD drive. Then go to the DVD manufacturer's website and under 'Support' you will see 'Drivers' (Manuals too). Pick the correct driver for the DVD model you have and download it. After downloading, install it.
Another way to install drivers is to go to 'Device Manager' (Control Panel ---> Administrative Tools ---> Computer management ---> Device manager).
In Device Manager, you will see the DVD listed. Right click on it and disable it. Re-start the computer. Windows will find 'New hardware' and install the correct drivers.
