The fact that it goes all black doesn't really give me an indication of what it could be, If it was somehow a hard drive failure there are data recovery techniques and stuff if it has really important data. This is why its good to backup all you're important files on a USB drive as I've had the same kind of stuff happen before. Did you check BIOS at all to check if your hard drive is showing up?
