It happens to all of us at some point. You turn on your trusty computer that has not failed you in the past 4 years and all you see is a black or maybe blue 
screen. In some cases the screen might even be white. In yet other cases, you might not see any activity at all. Your first response is a sense of severe frustration or even a slight sense of panic. This can be especially true if you rely on your system for your job. The only comforting thought is that you have all your information backed up on an external drive. You did back up your system, didn’t you?
