If the CD-ROM will boot from a recovery CD, then this would indicate a Windows software problem instead of a CD-ROM issue. It can usually be attributed to a corrupt driver. To reinstall the drivers:
1. Go to Start>> Right click My Computer>> Properties>> Hardware>> Device Manager.
2. Expand DVD/CD-ROM Drives line item.
3. Right click on the items below and select Uninstall drive on the resulting menu.
4. Re-boot the system and Windows will automatically detect the CD-ROM drive and re-install the drivers for you. 2. Try a different media - some brands will just not work correctly with a given CD-ROM drive. Watch out for compatibility problems with Maxell, Memorex and Macromedia CDs. 3. Check for unusual noises, maybe a ticking type noise. This could indicate a cracked disk. Or, the media may not be seated correctly on the spindle. 4. Is the access light on? 5. Is the CD Clean? 6. Check error messages in Event Viewer. Here's how:
Go to Start>> Settings>> Control Panel>> Administrative Tools>> Computer Management (or Event Viewer) 7. Check your manufacturer's web site for software updates and drive updates. Check for QSI firmware updates. 8. For DVD - Are you trying to write to a DVD that is READ ONLY? 9. If all has failed, you may be faced with performing a complete Operating System Recovery or Repair (preferred). 10. If nothing above has worked for you, then you may need to take the drive in to a service facility for repair or replace the drive.

Using System Restore
2. If you added hardware or software to your computer immediately before the issue started, remove the added hardware or software. Be sure to turn off the computer before removing hardware. As with any problem that arises with computers, reversing a process that started a problem may correct the problem. 3. Be sure to check the obvious:
* Are the speakers turned on and have power? * Try unplugging the speaker power adapter and keep it disconnected for 30 seconds or so, then plug it back in. * Try plugging a known working item (such as a lamp) to check the wall outlet for power.
4. Check to insure that the Mixer Control volumes are set to 3/4 volume and are not muted. Analog or digital can be set in the Mixer Controls, depending on the type of sound card and speakers used. 5. Make sure that all connections to all speakers are fully seated. Usually, these plugs click twice before the fully seat. 6. Try plugging in a known working set of head phones to ensure that the sound card is functioning. 7. Try plugging in the speakers to a known working portable CD player that will accept the same connection. This will determine if the speakers are working. 8. Go to: Start>> Control Panel>> Administrative Tools>> Component Services>> Services. Make sure audio is enabled. 9. Go to: Start>> Control Panel>> Administrative Tools>> Services>> Windows Audio. Make sure "Windows Media" service is running. If it's not, right click on this service and select "Start". 10. Go to: Start>> Control Panel>> Sounds and Audio Device Properties. Be sure that the "Mute" checkbox is unchecked.
