Try using the command prompt to verify the DVD drive at the hardware level.

To enter safe mode, you will need to use a different process since it is Windows 8.  With Windows 8, it is much easier to enter safe mode with msconfig.

Go to the Start screen and search for msconfig and open the result.

On the boot tab, enable safe and network. 

Click apply/ok and reboot the system.  It should boot into safe mode.  Once in safe mode and done with the steps, launch msconfig and enable normal boot on the main tab to get back to normal mode. 

The following was taken from Here.

Use the following steps to confirm that the drive can read discs from a command prompt.

1. Turn on the computer, and press the F8 key repeatedly at the logo screen until an Advanced Boot Options screen appears.
2. Select Safe Mode using the up and down arrows on the keyboard, and then press the Enter key.
3. When the computer boots into Safe Mode, click Start , type CMD in the search field and press enter to open a command window.
   
4. Type diskpart at the command prompt, then press Enter .
5. Insert a data or movie disc that contains files into the optical disc drive. Do not use a music CD. Use the type of disc (CD or DVD) that is not being recognized in the drive.
6. Wait about 20 seconds for the disc to achieve full spin velocity.
7. Type list volume at the command prompt and press Enter .
8. Using the table that is displayed, look at the column labeled Type and find the DVD-ROM (or CD-ROM), and then locate the drive letter in the Ltr column, corresponding to the drive.
   If no CD/DVD drive exists in the Type column, go to Reseating the CD/DVD Drive .
9. Now that you have identified the drive letter for the optical drive, type Exit and press the Enter key to end the DISKPART command but leave the command prompt window open.
   Do not click the in the upper right hand corner to close the window.
10. Type the drive letter for the drive followed by a colon ( and then press Enter key. In this example 😧 .
    If a device is not ready error message displays, the disc or the drive may be bad, or the drive door is not closed properly. You may wish to test the drive by inserting a few other discs of the same type to make sure the problem is not with the disc. If other discs of the same type cannot be read, contact HP Customer Care.
11. Assuming there is no error message, type the directory command DIR and then press Enter key to display a list of files and folders on the screen.
    • If a list of file names and folders is shown on the screen, the disc is recognized by the drive. The issue is not likely related to the drive or the disc. It is probably related to the software configuration in Windows. Continue troubleshooting by reinstalling the device driver in Device Manager.

    • If the message "device is not ready" is shown or the screen fails to update after 30 seconds, the disc or the drive may be bad. You may wish to test the drive by inserting a few other discs of the same type to make sure the problem is not with the disc. If other discs of the same type cannot be read, contact HP Customer Care.
12. When finished displaying the list of files on the optical disc, type Exit and press the Enter key to close the command prompt window.

Let me know the results.

Many thank, the "Regedit Fix" upper and lower boundaries fixed this problem . I had two Optiarc drives that exhibited the smae problem, working OK one minute then stopped the next. I suspect that it was MS Windows 7 update but can't prove it.
