iMac G4 making loud beep after optical swap and Tiger upgrade
Hi! I replaced a customer's dead Superdrive in an iMac G4 1GHz, wiped the hard drive and upgraded him to Tiger, and threw in an additional 256MB, for a total of 512MB. I also installed an Airport card, connected to my wifi, and updated the machine to 10.4.11. I used it for two days after the procedure, and all seemed fine. He's telling me that yesterday he was using the machine, and it make a startlingly loud beep, and showed text on the screen, and he had to kill the power to get it to stop. Today he tried running Software Update, but in the middle of the process he got the "you must shut down" box. I told him to reset the PMU and PRAM, and it seems stable for now, but I'm not feeling so confident. If he calls back I think I'll have him pull the additional RAM I put in, and reset the PRAM three times.
Any ideas as to what I could have done wrong? Thanks in advance!
