i reiceved an A1311 imac from a friend
it start, boot and after loading Apple and full loading, reboot.
i tried to install fresh Os (sierra) from usb, all work fine from boot Usb, i can format hard disk (mine disk to test if is a problem of old hard drive), start install of Sierra, all work fine and tell me that installation is ok, reboot, and again same situation of previous...
during boot seems not read correctly keyboard command for diagnostic or others commenad,
work only combination to reset Parameters ram, no more.
some suggest how to check problems?
i tried to start from disk with old tech tool, but not complete the boot.
