Before I open up my computer I need to know what do I have to do. The only thing that I want to do is take my old cd drive out and replace it with my new internal cd burner but I need to know do I suppose to take my whole computer apart or do I just take the cover of because I am scared that if I take my whole computer apart I will mess something up. From what I was told is that I have to take the cover off of my computer and take my old cd drive out and replace it with my new internal cd burner. So could someone tell me which one do I suppose to do do I take my whole computer apart or do I suppose to take the cover off of my computer and take my old cd drive out and replace it with my new internal cd burner. I am hoping that I dont have to take my whole computer apart because I am so scared that something will go wrong. Please help me. Thanks
