To uninstall/update drivers --

Go to your control panel and look for "System Properties". You should see a button that says "Device Manager" under the "Hardware" tab. This will bring up a new "Device Manager" window.

You should now see a list of devices on your computer. Search for your DVD drive or what have you. Right-click it and choose "properties". This will bring up a new window. Click the "Driver" tab. Now you have a few options.

Choose "update" to update the driver. It will search the internet for a newer version. If you do update it and find more errors, then you can always click "rollback driver" to revert back to the previous working driver. And uninstall obviously does as it says

PS: You can also find the model number of your device this way, it will show up under "Device Manager" as the make and model of your drive.
