Is the keyboard plugged in? j/k - Sounds like the hard drive is done for. But it's impossible for us to guess. –  Ƭᴇcʜιᴇ007 Mar 10 '11 at 23:59

It could be many many things, and since we can't see it or touch it, it's impossible to tell you. You're either going to have to start searching/guessing/trying and asking specific questions, or take it to someone who knows how to fix it. –  Ƭᴇcʜιᴇ007 Mar 11 '11 at 0:05

Most likely your hard drive is dead.

Try with a different drive, and then you can test if the cabling is a problem.

It's unlikely that the BIOS is causing the keyboard not to respond.

I don't understand your question. –  user3463 Mar 11 '11 at 7:40

The computer is most likely hanging while trying to detect the hard drive, which may well indicate a faulty hard drive or cables.

If possible you should try replacing the hard drive and cables (but one at a time) to identify which of them is the cause. If at all possible borrow them from either another computer or a friend; after all, you don't want to have to buy a new hard drive when it's the cable that's faulty.
