It could be that the DVD laser has gone to heaven.
As it is comparatively new it should be replaceable under warranty.
The only driver that is required is the basic Windows CDROM driver which is automatically installed by Windows and which is obviously OK as the CD side works.
Only possibility left if you haven't tried it is to Remove the drive in Device Manager and reboot - Windows will Find New Hardware and reinstall the driver.
If no joy then it seems like a warranty replacement.
