Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
How old is the computer?
What is the exact message that appears on the computer's screen, please? this is a crucial detail that I need to ask to be sure of.
That may be an indication of a severe hard disk failure, or hard disk crash.
Does anything else show on the screen?
Has the CPU box been moved lately, or at all?
OK. Turn it Off (if it is On.)
Wait several minutes.
Turn it On again, and immediately press F2, and try to get into the SETUP, and run the Disk Diagnostics. Let me know what result that has.
I suspect that your hard disk has failed.
I hope that you did not have data on it that has no backup.
You might need to take this to a shop to have it looked at, repaired, or the hard disk replaced. (If it comes to that last, expect a considerable charge for reinstalling Windows - unless you have Windows install media, or Restore CDs, in which case, you could try those first, before taking it to a shop, once you have made sure that using a Restore CD to reinstall Windows would not wipe out data that you would rather not lose.)
Well... that is what the signs indicate.
I think I should turn this case over to another Expert here... I have Opted Out, which opens the case to other Experts in this category, without additional charge to you.
Thank you for your patience meanwhile.
