Press and hold power & volume up for 5 seconds then try again

Have you tried holding volume up and power buttons at the same time untill you feel 3 vibration not one as three will come soon after, You may also wish consider a system repair but this will factory reset and erase all data on your phone

I agree with thommo if nothing work just either try to boot on safe mode or repair the phone with PCC

PC Companion (PCC)

Bridge (for Mac)
