I have a Canon PowerShot ELPH 100 HS. When taking a picture, the capture preview that pops up on the camera display for a few seconds is a bunch of static looking colorful squiggly lines. Then not even the static stuff nor the picture saves at all. I've tried a different memory card and still nothing.
