Hmm Actually its a hard disk of a laptop. I saw a message before I shut down my computer that I should back up my files since there is a hard disk failure ( I don't exactly remember the message). When I turned on my computer, it will stop responding after the boot screen. I can't even press the f3, f11 or del for the recovery, setup etc. I think the hard disk stop running or something.

There is no loud noise and its 1 and a half year old. So not that old.
