I sent in my iMac G5 last week to get the PSU and Logic Board replaced thinking that was the problem (computer constantly shutting off). I get a call today from the tech dude, his like you are not running the proper memory on your iMac. I was shocked seeing I bought the computer directly from Apple and never touched the memory. Which is pissing me off right now, my computer only started having problem 2 months ago with shutting off. Yet I've had the computer since September 2004. I think they put the wrong memory back in, because it doesnt make sense that Apple would send a computer with the wrong memory. If so, what do I do now?
