very blury pictures on this camera

well this is probably an easy fix but i cant find anyone having the same issue i got this camera a long time a go but after a year of use it started making extremely blurry pictures, i have fiddled with the options but nothing, i noticed that when the camera tries to auto-focus it has some sort of issue, it makes a noise than goes even more blurry, i don't depend on this camera so i am prepared to take a risk and take it apart if necessary.
