G4 temps acting crazy

2011-08-16 Thread Nick Adams

Greetings,

Normally my Mac temperature is around 137ºF and if it is a real hot  
day, it may rise to 139º F. The fans usually stay at a constant rate.


A few days ago, a few minutes after booting my computer in the  
morning, the temperature started rising above it's normal range and  
rose to around 140ºF and rising, the fans kicked into overdrive.
I immediately restarted the Mac and everything returned to normal, and  
remained normal.

This behavior happened again today.

Up to the first occurrence a few days ago my Mac has been rock steady.

Does anyone have any ideas of what might be going on?
Do heat sensors fail?

Power Mac G4 MDD 1.42 Ghz
Sonnet Tempo Serial ATA 2-Port Internal Serial ATA PCI Card with two  
Seagate 1 TB hard drives

2 GB memory
Two fans installed behind the CPU, blowing out

Dust build up, particularly hot days, failing fans, there's a long line of 
possible failures before temp sensors go wonky; they're pretty simple and 
stable things.

My first step would be to open it up and blow it out with canned air. (outside! 
You would be amazed at the havok a charging dust rhino can wreak 8-)

Then I'd make sure both fans were in fact turning.

Look at Activity monitor when it's started up and cranking along. If something 
is causing the CPU to spike, maybe there's something going on software-wise to 
cause this.

Under Keyboard tab Keyboard Shortcuts have you hit the Restore
defaults button?

tried that - no joy

 Do you have any additional software installed? Specifically the haxie  
 called Menu Master allows the custom reassignment of menu keyboard  
 commands.

yes I do have Menu Master installed but only one hotkey initiated
there-no shift-colon

 Some non-Apple keyboards have issues, and some Apple keyboards have  
 firmware updates available. Have you tried an alternate keyboard to  
 see if it's keyboard specific or system specific?

yes, tried alt keyboard - same issue

tried booting from alternate disc - problem goes away

wondering if I can restore from my backup disc somehow, last back up
two days ago
so not sure how to restore system files without losing new work (using
SuperDuper)

 99% chance this is a Menu Master problem. Perhaps look in your ~/
 Library/Preferences folder for com.unsanity.menumaster.plist and trash  
 this file.

100% chance.  That did it.
Thank you Kris

I've heard about Haxie issues but haven't experienced much.
Do OS versions later than Tiger offer contextual menu customization?
