Guys I don't know what to do, I unplugged and replugged everything and let the computer "repair disk errors" or whatever and it still is dysfunctional. I would find it very hard to believe that this is a serious problem because the computer is only 2 years old. What do you guys propose that I do? Do I have to buy new software, a new unit, get professional help, or call and get a walkthrough on potential ways to fix this? I really need to get this thing working or get a new unit by Monday because my work is dependent on filing my paperwork everyday. Also, I have thousands of files (that I believe are backed up on something) that are on this computer and that are essential for my work. ANY input is helpful, thanks.
