Can you tell me please the model of your camera?
Can you remove the battery please then hold the shutter button down for 60 seconds then release.
Wait 5 minutes, put the battery back in and turn it on.
Tell me please if it now operares correctly.
Can you put a different memory card in the camera, and tell me if you can then take a photo please.
Can you insert the memory card directly into your computer?
If so, is it windows? Which version? And which drive letter does the card show as?
Click on this link and it will tell you
