A local pc shop brought in an imac that hangs up during start up, I tried it with my test drive and it did the same thing. I ran ASD EFI everything passed and i ran OS and everything passed there too. i figured it was likely the graphics but it passed the test. what would you think the issue is? his client is persistent to have it fixed. i have replacement parts in stock to swap anything you might think.
