Store Manager: Hi, my computer is frozen and it won't do anything.
Me: Ok, can you reset it?
SM: How do i do that?
Me: Use the mouse to press on the start
SM: No, the mouse doesn't move.
Me: Ok, in that case restart it by pressing the restart button.
SM: Where is that?
Me: Its a button on the PC.
SM: Is it on the keyboard?
Me: No, on the actual computer.
SM: OH, I don't have one like that
Me: Ok... Then just press the Power button on the computer.
Me: So what did it do?
SM: Nothing, its black now.
Me: Ok, now press the same button again, and it will turn on.
SM: Ok, nothing happened...
Me: What do you mean?
SM: The same screen came back up, its not doing anything!
