Gopro Hero 4 Silver keeps freezing

I turn it on and it immediately freezes I've tried everything and nothing seems to work. Do I need to replace something?

i have the same problem, it turns on, the display comes up correctly, when i press the record button, it instantly freezes. I was able to successfully navigate to the settings to reset the cam and also format my disk, but the minute i do this, the camera freezes again. I have to hold mode button for more than 10 secs to turn off the camera.
