The camera tricks me to erase my pics.

the camera asks two very different things out of nowhere. its something with power off and something else. if you choose power off the camera will turn off but when you turn it back on, the same thing will display. if you chose the other option, all your pictures will get erased. There's no other alternative for this, but erase all your pictures or you're just going to press power off and do the same thing until the battery dies. what can i do?
