My Toshiba is stuck on "Toshiba Leading Innovations" screen

When i turn my laptop on, it get stuck on "Toshiba Leading Innovation" screen. The current solution that i found is to unplug and plug the battery and it does work sometimes and sometimes not. So the problem happened everytime i turn on the laptop.

I formatted the laptop and even restore it to the original Windows 8.1 and installed all the updates, the drivers but nothing solved the problem !

My laptop is :

Toshiba Satellite C50-B-14Z

Windows 10 Home

Intel® Celeron® N2840 processor with Intel® Burst Technology 2.0

Hard Disk 500 GB

Intel® HD Graphics
