I upgraded a Sempron based machine to Vista Business Enetrprise, and the DC DVD drive no longer works. In Control panel/System/devices it say every thing is OK.
But when you put a CD in, it does cannot read it.
I have followed some threads toa Microsoft post that say in regedit delete the upperfilters and lowerfilters. But these entries are NOT there todelete so this isnot an option.
I have loaded the latest flash bios drivers for the Lite-on SHM 165P6S, still no joy. Any ideas?

Can it read a DVD disk? If it can read a DVD and not a CD, then the CD laser has died.... there are two different lasers in the optical drive, one for the DVD side and one for the CD side. It could just be very dirty, in which case use a standard CD cleaning kit, or replace the drive. Cari (MS-MVP) Windows Technologies - Printing & Imaging coribright.com/windows
