My powermac g5 is just over 5 years old. It's been working great up till about half an hour ago. Here are the pictures of what it does when it boots up, can anybody read into this? here is what i do know: Boots into firewire mode - HDDs still work Graphics card still works What I don't know: dead memory? dead motherboard? dead cpu? I'm hoping it's the memory... but how do I test for this? any insight would be appreciated!!
