I wonder if anyone can help me, I am a silver surfer with a bit of computer savvy, but since re-installing my operating system, (Windows Xp SP2 2002version) Things seem to have gone awry! I had been reloading all my bits and pieces over the last couple of days and everything seemed ok until I put a cd into the drive and nothing happened. When I checked the device manager I saw the exclamation marks and read this message. "Windows cannot start this device because its configuration (in the registry) is incomplete or damaged. (code 19) Click troubleshoot for help etc" Well I tried to open the troubleshooter and that wont open. I have a Liteon cd rom LTN 5265 and a LG dvd writer. Can anyone HELP?
