My iMac can't boot any system, kernel panic?
Hi, first of all thanks for any help that you can provide me.
My computer can't boot the system, at the first time start to can't find the system and show me a folder with a question mark, so I try to reinstall the system (Lion) and can't boot from the CD or USB, just show up the apple symbol but never more than this. So I proceed to change the HDD for a new one and make a special partition with a bootable "OSX Lion Install" saved inside, and have the same problem.
But then in the apple logo screen start to appear the despicable screen of death (mac version) with the restart message or sometimes just the apple and a kernel panic code in the back, exactly this one:
''''panic(cpu 1 caller 0xffffff80002c2cb5): "Machine Check at 0xffffff80002bcb60, registers:\n" "CR0: 0x000000008001003b, CR2: 0x000000010f66c370, CR3: 0x0000000000100000, CR4: 0x0000000000000660\n" "RAX: 0x000000009cc01065, RBX: 0x7fff

------------------------------------------
After this I change the RAM memory and use the "Apple Service Diagnostic Disks" (ASD Dual Boot 3S123), for make a test of all the computer and the computer pass all the test without a problem, so the Apple Service Diagnostic Disks says the hardware haven't problem.
So I think this is a software problem. After this I try to upgrade the EFI/Firmware with the "FirmwareRestorationCD1.3" and follow all the instructions for do that, but the computer never show up a blinking light or a sound, like the manual say, just delay the start screen, but never read the disk. So I can't upgrade the Firmware.
After this I try all the start up combinations, delete the NV RAM, start up in safe boot mode, in verbose mode and nothing happen. I try to start in single-user mode and show up the kernel panic message again:

I try with a different system installation and with the original one come with the computer and have the same problem. I start to think this is a Logic Board exactly the CPU problem, but If someone have another idea can help me I really will appreciate it...
by the way, sorry for the bad English, is not my native language.
Thanks for your time : )
Это хороший вопрос?
