The CD Rom in a system I recently built is now refusing to autoplay data disks. It autoplayed them fine until a couple of days ago. I can access the info from the CD, so it is still recognizing the D drive. I have unchecked, rebooted, then checked and rebooted the computer changing the auto insert notification setting in the CD properties. What else could I try? This computer is being used by novices, so I'm not sure if they changed any files or settings. Thanks for your help.
