PS4 won't start?

Hi guys, when I start my ps4 I get an error message (Can't START THE PS4 CONNECT THE DUALSHOCK 4 USING THE USB CABLE AND THEN PRESS THE PS BUTTON) and then of course I did that after I pressed the ps button this picture

Why did that actually happen, please help me if you can

Since something like this happens more often, you can download the latest update / reinstallation file from the official playstation website and load it onto the ps4 using a USB
