My RPi 3 resets itself after every reboot. All my settings, customizations etc are lost. Keyboard layouts, date/time setting, setting in the
sudo raspi-config (camera setting etc), desktop customizations, everything is lost every time I reboot my Pi.
I am using a 16GB Sandisk memory card which came with my Pi, NOOBS preloaded.
All the data however, which I store on the Pi, web browser cookies etc are left unharmed. I complied OpenCV libraries on my Pi sometime ago and they are also there.
What is this problem and how do I fix it WITHOUT HAVING TO FORMAT MY EXISTING CARD OR BUYING A NEW ONE.
