My cd/dvd drive will not work at all. In device manager it shows an !. It also tells me it does not need to be upgraded. I cannot find any upper or lower filters. When I search "regedit" nothing is found. I am "partially" literate in all this, but I can follow directions, so if you can offer me assistance, it would be greatly appreciated. This drive has worked in the past. And at some point, these filters were there. Thanks.
