I'm going to assume that you are using Windows 7.
1) Click Start
2) Search (without quotes), "Device Manager" and press enter
3) Navigate to "DVD/CD-ROM Drives"
4) Check to make sure that the drive is recognized
5) If so, right click the drive, and click "Update Driver Software"
I'm not 100% sure that this will work, as I have never uninstalled a CD drive before. Couldn't hurt to try though.
