Q: Late 2006 iMac, Lines, Kernel Panic, Freeze, Reboot, Restart, Serial W8 ?

Hello,

Let me start by explaining the method I am initially going to adopt in my search for answers;

•All of the keywords and more that would not fit in the title space, relate to my problem.
•I think the *iMac Serial* holds the key to mine and possibly a lot of other peoples search for answers.
•My second post will explain what I know about the Serial and the information it provides.
•I have a strong feeling that a lot of people who have the same or similar problems to me will have a Serial that begins with at least W8.
•I believe that a lot of affected machines will of been produced between 2006 & 2008, yet not confined to that window in time.
•So, to round up, I am looking for people who have had/are having the same/similar problems to the ones listed below.

•Small graphical glitches; Thin lines in random areas on the desktop, growing in number and intensity over time.
•Graphical glitches on, in and around Finder windows. Again, growing in number and intensity over time.
•Horizontal lines across entire screen. Again, growing in number and intensity over time.
•The odd Software Crash/System Freeze. (Which does not happen very often on the iMac we've grown to love)
•More frequent Software Crashes/System Freeze's. (Maybe it's all that freeware and plugins I've been playing with)
•Kernel Panic's, never had one before... it was a new one on me.
•Frequent Kernel Panics.
•System Freeze, recovering after being put to sleep and then woken.
•System Freeze, unrecoverable. Hard reset required.
•Exactly the same behavior after a full reinstall of OSX.
•Exactly the same behavior after wiping system drive with zero's, then a full reinstall of OSX.
•Exactly the same behavior after wiping system drive with zero's, then a full reinstall with a previous version of OSX.
•System Freeze requiring hard reset on nearly every occasion Time Machine was accessed.
•Shut iMac down completely, never to respond to Power Button being pressed again, even after trying to reset the SMC.


The above is a simplified list of key events on a relatively short journey from Perfect Machine to, 'will not power up'.


If you or anyone you know has gone through anything similar, I would love you to join this topic.

Yours,
GaBeech

    My late 2006 iMac has recently started exhibiting the problems discussed in this group, and I spent an hour reading the entire thread (I guess I have been fortunate as most of the posts date to 2010). This iMac does not have Growl or Dropbox loaded. I did load smcFanControl, which had been suggested several years ago and I am waiting for the machine to fail.

    After running smcFanControl for 24 hours the machine has not locked up regardless of the number of applications open, and with streaming in the background. There is one proviso: I must keep the temperature below 109ºF. That is the point, for me, at which the machine freezes. To keep below that temperature I adjusted smcFanControl such that the fan is on almost constantly running about 3800 rpm. The 'white' noise is not a problem, though constantly running the fan is another issue.

    Just to revive the topic. I've been having the same issue with my iMac A1207, for 2 years now. Anybody had any luck fixing this issue without replacing the motherboard?

    It is working fine in safe mode. SMCfan control worked for a few months, but after a while the video crashes started to get worse, until it would crash before starting.
