Optiarc DVD Drivers

I have a 7805u FX, and after upgrading from Vista64 Home Premium to Ultimate, the driver for the DVD player is not loading properly.

In device manager it says:

Optiarc DVD RW AD-75835

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

 

Follow these instructions:

Microsoft Windows Vista

1. Click Start button
, and then click All Programs.
2. Click Accessories, and then click Run.
3. Type regedit, and then click OK.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
4. In the navigation pane, locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5. In the right pane, click UpperFilters.

Note You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 8.
6. On the Edit menu, click Delete.
7. When you are prompted to confirm the deletion, click Yes.
8. In the right pane, click LowerFilters.
(If you do not see the LowerFilters registry entry, then skip this step.)
9. On the Edit menu, click Delete.
10. When you are prompted to confirm the deletion, click Yes.
11. Exit Registry Editor.
12. Restart the computer.
