"no memory card"

Memory cards go bad, that?s a fact of life. I?ve found that trying to read a camera formatted card in a PC is not always a reliable test, borrowing another working card and trying it in your camera is. If you can?t borrow one another cheap test is to purchase an inexpensive card and trying that. You can generally find older (smaller capacity) cards on sale for $20 at Best Buy. If a new card doesn?t work then I would go the route of repair shop?..

Umm if it was dropped and this is occuring after i would suggest taking it in to get repaired...

However if you have a card reader or anything like that(most new labtops have the built in) shove the card into one of them and see if the computer can read it...if computer can read it I think the camera needs some work.
