1 24 intel I mac Froze!?
24" i intel mac erly 2008 3.06ghz + 4gig+ nvida GT 8800 video card (I bought it in June 2008. Never had a problem with him)
The problem: Operating system Froze/Stuck. I turned off and turned on but it is not caming up. Sent to the lab, they said the board should be replaced. I bought a board and installed all the accessories that exist on my board, but the problem remains.
I replaced the new memories. I tried to bring up a cleen operating system installed on an external disk + tried installation disk but all failed -agin, just can not get past the white screen!!
Apparently there is no connection between the cleen operating system / installation disk and the computer hardware.
What is strange is that I can bring up vista form the bootcamp (but do not play FHD video Properly.) - meaning, graphics card, is not dead!
What do you think is the reason of failure the ability to bring up the operating system - "mountain lion"?
(I checked all connections everything fine there).
Update
If i am not wrong I also tried without peripherals and no change.
Although I do not care to try again ...
The question is, whether is there any chance that this problem is still coming from video card damaged? Or the power supply?
If so, what way to test it?
By the way, this is a phenomenon that happened to me twice on the windows
Is this a good question?

Have you tried a safeboot to the external disk? I suspect a missing EFI update on that logic board or update to the external OS.

I DID tried a safeboot to the external disk WITH the shift key Pressed ( Is that what you mean?)!?
what is a EFI update, and what do i need to do Now to fix it?
(24" i intel mac erly 2008)
By the way, I removed the inner disk and tried to bring up the operating system installed on it When connected externally to another computer. - Disk / system came up without difficulty! - But I can not bring up the hardware on My Computer ....

I want to bring up some more details about how things happen form the beginning.
I hope it might help with something to diagnose where exactly is the problem can be.
I was running the lion for some time. Suddenly one day the system froze for three times. and the third time it was not coming up anymore! - just cannot get past the white screen!!
At this point, I was sure it was related to the fact that the disk was filled to capacity....!
Took it to a lab...
At first Laboratory at my aria clime that there is a problem with the disk and further diagnostic that apparently the board is dead!
I bought a motherboard on eBay, replaced it myself but the problem remains.
I went to a friend who knows Mac, and somehow, he discovered there was a problem with one of the memories stick, and surprisingly he managed to bring up the operating system with a stick one! He made it through the recovery system - but, we still noticed a strange problem -resolution color screen that appeared funny here and there...
The next day I bought memory and the computer went back to work "as usual" - it was not quite normal, because the operating system was not coming up as fast as usual, but overall it functioned pretty normal.
At this point I thought maybe it would be good if I upgrade to the mountain lion. So that's what I did.
after that, That day I moved a large amount of data from three different Heard disks simultaneously and cross. I let the process go on all night alone. When I woke up next morning I saw the Computer froze and that was the picture http://www.pbase.com/image/145736195

Did you ever find out a fix? My iMac is doing the exact same. I'm not sure if I should start my own topic or not. Thanks.
