I have no !-mark associated with the drive in Device Manager. I tried Disable Driver Signature Enforcement option I tried uninstall drive and restart . . Nothing helps!

No resolution yet. I am Using Pakard Bell easy note T6500 RS 66 .. please help.....

It's not that you were being ignored but I cannot find any drivers or firmware updates for Matshita UJ-875.

The drivers for your computer are >>HERE<< but there is nothing listed for a DVDRom which supposedly means it uses the standard W7 drivers for that.

Plus you said there is not a missing driver flagged in device manager.

My only advice would be to message Packard Bell Support from the link I listed.
