Why won't Asus ZenFone 5 open?

My ASUS Zenfone 5 will not open.  Just searching ball @ ASUS IN SEARCH OF INCREDIBLE screen.  I've re-set 3 times and it works for about 20 minutes and then goes back to this screen?

my zenfone 5 wont turn on after a failed rooting.... its because while i was rooting i accidentally touched the usb cable and it got disconnected from the computer. What should i do?

Remove the battery for few minutes before trying it again. If it is the same.

Let me know how it goes.
