my camera (a sony cyber shot dsc-w35) has gone weird. i accidently dropped it and everytime i turn it on , the screen displays the options for displaying date and time. then i either click cancel and ok, and then the button to view the photos but the screen turns white and "access" keeps flashing up, viewing pictures from albums i havent seen before.... i want to view photos i have previously taken but it not working, what should i do??? is there a way to reset it?
