I would also tip to the new ram module as well as the first culprit. The original poster did not mention if they had tried to reboot without the new ram module? Only that they had removed it... The check with a second hard drive is a good one to see if it will boot into target mode. Did you use sufficient anti-static measures when inserting the Airport card and new memory? This could have caused some damage if you were unaware of this or chose to ignore it? Have you tried resetting the PRAM as well? HTH, Richard --
