I have an asus k52f-bbr5 laptop, i have used the dvd drive many many times and yesterday it started reading dvds wrong, now they are all in inverted colors and i didnt change any settings, is this an easy fix problem or do i have to go find parts, im not sure of my warrantee on it but i would rather not send it in just to lose all my files and things like that, which has been known to happen occasionally.
