If any hardware has been recently added or the computer has been recently moved it is possible that the IDE or power cables connected to the hard drive or the CD-ROM drive may have become loose or disconnected.
Caution: When ever inside the computer ensure you are aware of ESD and it's potential risks.
Verify that the hard drive as well as the CD-ROM, CD-R or CD-RW drive have at least two or more cables connected to them. One cable should be a gray flat cable (data IDE/EIDE cable) and the other should be the power cable. In addition, the gray flat cable should be connected to the motherboard or the interface card on your computer.
If the cables appear to be connected properly, disconnect the data and power cables and then reconnect them to ensure that they are not loose.
