My camera was working fine last night but when I went to plug it into my computer it stopped working. I've plugged it in before with no issues. I changed the batteries thinking maybe the batteries died. But it still wont turn on..

The quality of the photos are very grainy. Not sure if it's just the camera quality or a setting, it seems like I've tried everything. Would love some help.
