Sony Cybershot DSC-W80 Blurry Photos

I have a similar problem. I bought my Sony Cybershot DSC-W80 less than 2 years ago, and it produced very clear pictures at first, but now they are usually grainy/blurry/fuzzy unless we are outside with lots of light. I have tried increasing the ISO and changing just about every setting, but nothing seems to help. Of course, the more objects are moving, the more blurry they are, but I cannot even get clear pictures of people or objects sitting still. Help! I have a similar problem.
