Hard Drive Not Found?

[buffbrad54]

I have a Dell laptop and recently it has been going into hibernate mode after I leave it on.. but when I return and move the mouse or click a button for the video to reappear it will not come back on. So I turned it off the other day and when it reappears, it will not do anything. What I presume is the hard drive makes a loud clicking noise and then the screen says "Hard drive not found.. No bootable device". Any guesses as to what this might be and might I be able to save my hard drive?
