Thank you for your reply.
I tried to boot in Open Firmware mode but it crashes almost imediately.
I have also Installed OSX 10.6 on an external usb hard drive of mine and tried to boot from that and it does exactly the same. I noticed that the external hard drive's light is on and binking while the computer is loading which means that it reads OS files. and after a while when the MAC freezes, the light goes completely off like there is no power supplied to it.
It does exactly the same thing even if i put the original disc that came with it and try to boot from that.
I entered Verbose mode again and now it always freezes after the "AppleIntelCPUPowerManagementClient: Ready" line
Also the keyboard is not responding and the lighs of the keyboard are off as well.
Thank you for your reply,
now that you said that about the CPU I oppened it and the Passive cooler that has on top of it, it is warmer than usual. I mean that I can touch it but it is very worm. The cooler works but it seems that it is not sufficient.
Is it possible that the CPU overheats and the MAC is freezing like that?
I disasembled the whole computer and re built it.
The CPU seems to be fine but in the logic board on the right hand side from the CPU I can see some kind of moisture. I cleaned it up with a cotton cloth.
It now shows more but it still freezes and I cannot access the Open Firmware option.
I went into Verbose Mode again and now it shows more than before!
It has a panic on CPU1 "pmap_flush_tlbs() timeout"
Here is something really strange....
While booting I pressed the D key and went into The Apple Hardware Test mode.
I did all the tests as well as all the extended ones, and guess what?
It Passed ALL H/W Tests !!!!
And I had it on for 2 hours in this test screen and it did not freeze at all, so the CPU heat issue is out of the question.
What the ..... is going on with this mac???
