98379 Sakar Digital camera

I bought this camera two days ago and first placed the batteries in today. I took pictures of my first day of spring break. Followed the instructions and downloaded the little cd thingy. When I plugged it in and changed/ cropped the old pictures it was fine. The view screen on the camera was blurry though.
Now my new pictures are all coming out dim litted and blurry. Kind of like lookinf through static. Why? What can I do to change it?
