Hi! I have an 24’ iMac from 2008. It started by freezing at startup screen, So I replaced the HDD thinking that was the fault, but the original HDD had no faults with it. Now when I try to boot it from a USB/CD it freezes at the loading circle ( Can’t enter the Resotre program) Tried an SMC Reset and also a NVRAM reset. Also tried with different RAM Sticks But it still freezes. Any ideas? Update (05/14/2017) Apple Hardware Test does not show any problems either.
