Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
how old is the computer and how often do you use the cd/dvd disks on the computer.
just for my knowledge i need to know roughly will it be more then 3 years old?
Just for your information and update, a cd/dvd rom basically work good for 2 years or so the lens which reads the disks gets weaker and dirty due to dust gets accumalated on the lens top which prevents the drive to read any disks and it depends on the disk condition as well.
you can try using a cd/dvd lens cleanser if the lens is good then it will start reading disks.
its a hardware problem and not a software however you may give it a try by removing the driver software and reinstall it back which works most of the times.
Open device manager and then check for cd/dvd drive and try to remove it and reboot the computer it will automatically pick the driver software.
restart the computer.
press the scan hardware button on the top and let me know if it scans the drive.
