Save The Date B Day Saying Nintendo DS Not Working Properly?

Nintendo DS not working properly? - save the date b day saying

I have a Nintendo DS a month ago. Until a few days ago worked perfectly. Wherever I turned, "said the Nintendo DS on the top screen and touch screen to play as many words, and" Do not touch the screen. " Well, says the top screen, the same thing, but the bottom screen is white. Then enter your name, fav color, time, date, and B-day. It will not save anything, he asks all the settings again when you go, and you do not load the game. Who knows how to solve this problem?
