What to do when your DVD Drive is not detected.

I was recently asked to install a printer for someone. They had the CD, but I found out the DVD/CD player wasn’t responding. I looked in the device manager and noticed there wasn’t a DVD/CD listed. I tried the add new hardware but it said no new hardware found. It is a Presario F700 laptop with vista. They said the DVD/CD used to work. I’ve never came across this issue before. What is wrong and what should I do? Thanks for your time.

This is most likely caused by an upper/lower filter issue. Simply follow these steps and then reboot your computer.

  1. Open RegEdit (Start>Run> Type “regedit”)
  2. Navigate to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}”
  3. Delete the “UpperFilters” value.
  4. Delete the “LowerFilters” value.
  5. Restart the computer.
  6. You might need to uninstall then reinstall any burning software you may have (Nero, iTunes, etc…) do this now.
