One of my processors just died . . . and then came back.

I just experienced 2 completely random freeze while doing pretty much nothing.



(WindTunnel dual 1Ghz, 768MB RAM, OS9)



I rebooted and an alert popped up exclaiming "The built-in processor test has detected a problem with one of the processors. Please contact a service technician for assistance"



I hit OK and it booted up into OS9 like usual . . .

Except in the System Profiler . . .



There was only one processor.



I rebooted, and there was no message and the processor was back.





I'm scared.



Anyone else ever experienced this or heard of this happening?



(corrected system message after repeat crash)

    I'd suggest you to run a Hardware Test using the Apple Hardware test CD.

    Did it.

    Done.

    Good.



    Everything checked out.



    I think I figured it out.

    Apple Service couldnt figure it out.



    Ma Warehoue is sending us a new one - but I realized the Turbo fan hadnt come on in a long time - which means the processor probably simply overheated and crashed.



    randomly the fan started working again and the crashes stopped.



    Still, I'm replacin that thing tomorrow with the new box.



    Scary.

    Heres a guess:



    One cpu overheated for some reason.

    When you rebooted it still wasnt functioning properly ( too hot ), and was disabled.

    When you rebooted again it had had time to cool down, and was fine.



    As to why it overheated, who knows, the temperature sensor on the board may have been flakey, and failed to speed the fan up to cope with the tempp increase.

    The power circuit may have been a bit funny, and was supplying to high a voltage, causing overheat.

    OS 9 only really uses one cpu, so I guess thats the one that failed, might have gotten stuck in an infinte loop with some buggy software.

    you really should switch to OS X with a dual machine, it's so much of an advantage.

    That, or the temperature sensor worked and shut off the processor when the fan died.

    Later that day, the TURBO fan came back to life and the machine didnt crash for the rest of the day. Weird Pt 1.



    When I started it up this morning (from being cold) I got the processor error message again - I rebooted several times and was unable to get it boot correctly. Weird Pt 2.





    But, we got the replacement machine from MacWarehouse today and swapped the drives - and I've had no problems with this one.

    The Turbo fan has only come on twice today, too.

    Which is far less than the average for the half-dead machine.





    AND



    when both processors were working on the othe rmachine the System Profiler said



    Processors: (2)





    but on this machine it reads:



    Processors: 2



    no parantheses.



    Weird, Part 3.





    My conclusion is that these new machines are simply . . . Weird.



    And I can't run OSX yet because we don' thave illustrator 10, or Photoshop 7, or etc etc.

    Not to mention Quark.

    &gt;=(



    But we will be ordering Ill10 and PS7 soon, so I will be able to work in X most of the time.

    Another funny note



    when we called Mac Warehouse yesterday, the Apple Rep happened to be there.



    So my boss talked to him and told him and the Rep said "OS9 only uses one processor."



    Oh sure, sure, blame everything on 9.

    (which does sorta-semi-support multiprocessors if programs are written for em, anyway)



    Apple isn't too keen on addressing any sort of problems that arise in OS9 nowadays . . .



    their solution for everything: "Well, just use OSX!"

    With that huge of a heatsink I don't see why they need turbo fans!
