can't burn a cd

[Eric]

hi: i have a 667 dvi.  a couple months ago it went into apple and the 
main logic board was replaced (under warranty).  At that time, apple 
also replaced the casing as it was all chipped.

When it was returned, i noticed that the case above the cd-rw drive was 
loose; i can push down on it, right where the casing meets the lighter 
gray part and it gives.

I also  can no longer burn a cd - i get an error message (can't 
remember exactly what).  I can import an cd, although it does not work 
every time...it hangs at times.

when I called apple, I was told to take it apart and pop it back into 
place myself.

I've been on a project and didnt have  time to deal with this.... I was 
thinking that perhaps the ribbon that connects to the drive is  loose.  
Also,  I am now no longer under warranty and did not get applecare.

So my question is what should I do?  I'm upset because this was all 
fine until apple fixed the casing...Getting ready to install panther 
and wondering if i'll even be able to do that with this drive.  Any 
advice or help will be greatly appreciated. Thanks, Eric
