DVD-ROM drive is not showing up on my laptop

DVD-ROM drive is not showing up on my laptop. The problem started after I updated its drivers this morning. I have windows 7 and I used the roll back driver feature but it didn't fix the problem. I also did system restore and rebooted the laptop twice.
I am using a super DVD – Super multi DL drive and this is the first time that I encountered this problem because my laptop is fairly new. I don't want to reinstall the operating system because I have a lot of files that needs to be backed up.
Do you have any other solutions that could possibly fix my problem?
