For determining a hardware failure with a cd-rom. Does Windows see the drive. If yes proceed to Troubleshooting steps A if Not proceed to Troubleshooting steps B 

Troubleshooting Steps 

A 

1. Is the drive able to read any cds. If so then specific cds may be damaged or need to be cleaned. If No to the answer proceed to the next step. 

2. The drive is not able to read any cds. If you have multiple drives such a cd-rom and Cd-rw or dvd-rom try the cd on another on of the drives. If that drive is able to read the cd but the drive your having problems with can't then try reinstalling the drivers for the cd-rom. If this doesn't work proceed to the next step. 

3. Try a lense cleaner for your cd-rom. If this doesn't work proceed to the next step. 

4. Apply hammer to cd-rom in frustration. Your drive is defective. 

Troubleshooting Steps B 

1. Is this the only drive that is not showing up. If yes proceed to next step if not and you have a cd-rom and cd-rw or cd-rw and dvd-rom chances are that you either have a virus or that your secondary IDE controller has failed. 

2. This is the only drive that is not showing up. Check device manager for conflicts. If there is no conflict proceed to 2a if yes proceed to 2B. 

2A Restart the computer and check the BIOS for the cd-rom. If the drive is not showing in BIOS then the drive is defective. If it is and Windows doesn't detect it try running the recovery and seeing if it will read the recovery cd. If so then you may need to complete a recovery.

2B If there is a conflict with the bus masters or another device remove them and restart the system and let Windows reinstall the device and see if that corrects the issue. If there are still conflicts you may want to consider running the recovery.
