Thanks for all the help. The computer seems to be running fine. I played a few songs through itunes and they came through the computer speakers fine, but still no chime when I boot the computer. I am at a lost as to why this is happening. I am hoping someone with a little more experience can explain this to me. Again, thank you for all your help.
Thanks, at least I now know what I need. I hope replacing the keyboard will take care of the problem. It will certainly be cheaper than replacing the logic board! It would have been nice if you could just replace the ribbon, cest la vie!!
