Boot Fail, Kernel Panic all the time.

I forgot to add That I did the PRAM and SMC reset but It's always K.P.

Hi IIIaass,

Since the computer don't start up and I can't acces the log file so I took a photo, tried to send it. Failed so I just type the message here. Please notice 3 lines before the end of the message here: Darwin Kernel version 10.8.0: Tue Jun 7 6:33:36 PDT 2011; r
something is missing after the r it was hidden by the "you need to restart your computer.".. I hope it's O.K. after all.

Thank you for your help.

So here is the message:

Following those instruction from GITHUB.COM,

• You need a bootable USB stick, for instance using Disk Utility's Erase with Format: OS X Extended and Scheme: GUID Partition Map.

• Let's assume the USB stick is mounted under /Volumes/USBstick.

• Download the AHT for your computer model from the list below.

• Mount the AHT dmg. Let's refer to the mount point as /Volumes/AHT.

• Copy the AHT to the USB stick and flag it as bootable

•

I’ve download the AHT, actually there’s 3 of them for my Mac Pro 3.1 .when I open it. the names of the Volume is all: AHTDOne.

Though the name of The Volume is ATHDOne I copy it to the USB stick I named : /Volumes/USBstick

Then I enter those to the Terminal: “cp -r /Volumes/AHT/System /Volumes/USBstick/

sudo bless --folder /Volumes/USBstick/ --file /Volumes/USBstick/System/Library/CoreServices/.diagnostics/diags.efi --label AHT”

And here is the result when I hit enter:

cp: directory /Volumes/USBstick does not exist

Louiss-MacBook-Pro:~ josephbuis$ sudo bless --folder /Volumes/USBstick/ --file /Volumes/USBstick/System/Library/CoreServices/.diagnostics/diags.efi --label AHT

Password:

No mount point for /Volumes/USBstick/

Can't determine mount point of '/Volumes/USBstick/' and ''

Louiss-MacBook-Pro:~ josephbuis$

when I try to boot with the USB by pressing the Option Key, the

/Volumes/USBstick do not appear at the Start up Manager.

I also tried to make a bootable USB With Disk Utility > restore ..Source.. destination..

But once again the USB drive now named AHTDOne is not in in the Start up Manager with the other bootable items.

Thank you.

Hi IIIaass,

Please ignore my previous message. Actually I finally found the Install disk that came with the computer. I make the test and here is the result:

4MOT/1/40000002: EXHAUST - 0

Would you please let me know the meaning.

Thank you.

Actually my back fan is not spinning.

So I pull apart everything. (Already did that once when a fan spin at very high speed and very noisy.)

I make a big cleaning, blowing weak pressure air everywhere - Pretty clean in there, not much dust - Also clean the Processor Heatsink, and even change the Thermal-Grease.

I put everything back. And now my computer is working. Front and rear fan is spinning. Everything seems to be O.K. At Start up it only says my clock is set to 2007. No big deal...

But when I check my video card radeon HD 2600 XT 256 MB the fan is not spinning; I don't know if it's normal or not but since I'm afraid that can heat up and cause new trouble, I just turn off the machine, and try to find some answer in line, but didn't fine anything about that.

I don't have special Apple thermal grease for the heatsink and I used the one for all PC.

If you have any Idea about the graphic card fan and if the thermal grease is O.K. Please let me know.

Thank you.

Actually I just wonder if it's normal at start up the video card is not spinning because the machine is still cold and after a while, when it's hot it will spin.

Now if my Card is dead, I think I can buy one at E-bay.

Thank you for all your help and advice.
