Hi,
Code 19 means there is a driver conflict such as two devices trying to use the same resources.
Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab - click
Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL - REBOOT
this will refresh the default driver stack.
Normally the above will fix that issue if not work your way down through these even if you have done
them before.
