A computer that will not boot up is often experiencing a hard drive failure relating to either file system corruption or mechanical damage.  Sometimes the computer will freeze intermittently, or else completely fail to recognize the drive.  In most cases the user will be presented with a DOS screen indicating that the hard drive is unrecognizable, missing, or damaged.  Files are suddenly inaccessible through normal means, and a professional evaluation must be conducted to discover the exact problem.

In many cases a user will see a screen similar to the one shown here, or possibly a blue screen with a similar message.  Hard-drive failures are a very common cause for computer boot up errors, and the data contained on the drive becomes vulnerable.  Power your computer immediately and avoid powering it back on to stop from damaging the drive further.
