I have an iBook G4 from 2004 with 256 MG of built-in RAM and an airport card. I just got a 512 MG memory card. The problem is, I can't get my computer to work correctly when both the memory card and the airport card are installed. They both work fine individually, separately. For instance, I can install the memory card and my computer will boot up and run fine, recognizing the new memory, but as soon as I pop in the airport card, the screen will either freeze up and turn crazy colors (if already turned on) or show me a black screen with the fan whirring (if installed before turning on).

On the other hand, once I uninstall the RAM and install the airport card, the computer is fine again, working perfectly. I just can't get the two to work harmoniously.

Has anyone had this problem before? I'm not sure what to do about it, besides taking it in, I guess. Thanks for any help.

Try installing both RAM and airport card and running the Apple Hardware test from the CD.

That's weird that that happened. Did you install the airport card software before installing the card? I think you have have to do that first.

I've had the airport card in and working for years -- it's just now that i've added RAM, and then screw the RAM shield back on, and pop in the airport card, the screen goes wonky and won't boot up right. The computer recognizes the RAM without the airport card in, and the entire system works again once I remove the RAM... They just won't work together.

did you try zapping the PRAM?
