On a computer I am trying to work on it gives the black screen with the can't load because of corrupt file and the part to put in the cd and push r for recovery etc. I went through the chkdsk /r and did a repair and recovery but it still won't load. I am trying one more time to see if I can recover. There is one thing that does happen. Periodically it will give one long beep, pause for a couple seconds and give one long beep etc. Any indication what it could be?
