iMac Freezing During Re-installation of OS X
iMAC 8. 1 Early 2008
My iMAC 8.1 had started freezing up. I was running Leopard 10.5, ordered and installed Snow Leopard 10.6. Then proceeded to do the additional updates - after each update the machine would freeze at the end of the update. Would have to reboot. Once the machine was up and running , I would check what was the version of the OS - and it would show that the update was successful.
After the updates the machine would still freeze and would have to reboot. I upgraded the memory to 4GB and replaced the harddrive with a 1TB SATA drive. I used the Snow Leopard disk and successfully installed the OS. But, during the account creation process the machine still freezes.
What other hardware issue do I need to investigate?
Is this a good question?
