A couple of weeks ago, my CD-ROM wouldn't play a DVD or recognize any CDs I tried to play. I checked my Device Manager, and under "DVD/CD-ROM drives", the one I have is "Slimtype BD E DS6E2SH". There is a symbol of the exclamation mark in a yellow triangle, so I clicked to see what was wrong. I don't remember what the code was for what it said, but I uninstalled the driver. Now it says "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" I just want to be able to play CDs again. What should I do? I have a Lenovo G770 which runs Windows 7. Thanks!! I also downloaded Driver Detective, which scanned it and said there was a problem, but they make you pay and register to do anything. I was hoping for some possible free solutions.
