How do I know if the mother board is bad in my Hero3 Silver?
We can determine if it’s a software problem or not if we factory reset your camera. If it’s a software problem it should be fixed by a factory reset. Factory resetting your camera will reset all settings you have configured!However, if you remove the SD card from the camera before doing a factory reset your videos and pictures on the SD card will be safe. While The GoPro is off, press and hold down the shutter button (the top button).While still holding the shutter button, press the power button (on the front of the camera).The camera will now power on and it will reset to the original settings.
Looks like a factory reset didn’t help, nor was the storage full. I think your motherboard may be indeed kaput. Replacing it should get you back into business.

I think there’s more then a software issue going on here, though.
the storage might actually be full or something and it doesn’t want to work. try deleting some stuff on the storage.
