<I cannot get stable image quality anymore. Just about all my pictures, whether on any setting on the dial, have a blurr. Is there a factory default setting?>
I've noticed that digicams are very sensitive to camera's movement when takes a photo. I don't know this specific model of camera. Try shoot the camera in a stable support like a tripod, a table, etc., using the timer in order to prevent camera's movement when press the shooter. use shooter speed of 1/60 or faster (better 1/250 if it's possible) and see the results. Select an still object to photograph and place it in the center of the frame, to make easy the camera's focusing. If your images are yet blurred probably the problem is within the camera
