worked for a while as a freelance computer technician. It's a classic among us the reboot issue. As they say: "it never fails". Rebooting is the solution to almost every problem in IT and computing.
However, if you have a basic knowledge about computers, it is better to look for a solution than to reboot just because.
I've always seen the reboot theme as a perfect analogy for the self-improvement theme. But that's another story. xD.
Love.
Yes, as a systems engineer I did not and will not see a class that tells you that reboot is a "Solution" because it is not a working tool for repair, but it serves as a guide for common users who get scared by anything.
