Are you volume buttons working well?I suggest you try power button+vol up until the phone vibrates.
Noting happened, volume keys work well.
Boot your phone in safe mode,see if it works:

So holding power and volume up for atleast 15 seconds gives no vibration - 1 is a reset - keep holding and 3 is a shut down
Thanks friend, it works well 
Anytime.
