Hello,

I installed windows 7 two weeks ago and everything worked well expect for the sound (5.1 doesnt work, still working on it). But yesterday when i wanted to watch a dvd my cd drive didnt work. i put it in but ni response but it in again and again no response. looked in "Computer" but it didnt show any cd drives. Only A: and c: (a: was a floppy drive which i dont have :s)
