look in device manager and post back if you find any errors or exclaimation marks.

there is an exclamation mark with yellow symbol. Thx

Bacillus,

Its next to the DVD drive.

"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click Troubleshoot to start the troubleshooter for this device"

ok, you will need to do this:

Go to start> run and type in "regedit" (without the quotes) then press ok.

1) Remove the Upperfilters and Lowerfilters values by:

a) Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it.

b) Expand the "SYSTEM" Key

c) Expand the "CurrentControlSet" Key

d) Expand the "Control" Key

e) Expand the "Class" Key

f) Carefully look for a key containing the following string of letter and numbers:

{4D36E965-E325-11CE-BFC1-08002BE10318}.

(The full path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} )


g) Highlight this key by left clicking once on it

h) On the right hand side you are looking for "Upperfilters" and "Lowerfilters", once you find these delete them by high lighting (left clicking on them once) and then right clicking on them and choosing "delete"

NB only one key may be present but still delete it.

Now reboot and your optical drive(s) should function again.

NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software.

Thanks Bacillus.

That worked.

good to hear.
