I have spent 4 hours with Dell tech support and twice I have been hung up on. So now I turn to the real experts. I need help! We did an update for norton antivirus and our computer shut down and could not reboot. Even if you try selecting Safe Mode or Last known good config it starts like it is going to do something and then shuts down and you are right back where you started. I do not care if I have to reformat my hard drive and reload everything but is there a way that I can rescue my files.
