Hello Holi77,
I'm sorry to hear that you are having issues with your camera. Have you tried the camera with just a fully-charged Canon battery inserted? I would suggest trying that. I would also suggest trying a different memory card if the camera powers up with the battery only and you don't get the error. If the error persists, then the camera should be sent to our service center.
