Freezing iMac Issue Due to Hardware?

[seanemac007]

There are a couple of threads on the Apple discussion boards (http://discussions.apple.com/thread.jspa?messageID=6952094) about very similar problems with older iMacs. In my case it is an iMac 6,1 (24" Intel Core 2 Duo 2.16 GZ, 3GB RAM) with the Nvidia 7300GT video card, the problem only started after upgrtding to 10.5, now I frequently get screen garbage followed by a video freeze. On one of the Apple threads someone mentioned that the problem disappeared when booting in safe mode, which I can confirm.

Did you just boot in safe mode and that was that??

iMac Freezing

The boot into safe mode is not a solution. My iMac continues to have the same problem although I have reduced it by using smcFanControl to keep the temperature down. See the discussion in the link in the original posting; there are now several dozen reports of similar problems with the only apparent resolution being replacement of logic boards.

Has anyone heard of the freezing occurring less frequently over time? I was able to trigger the freezing by just opening up Quick Time... then by opening up Safari... then Photoshop... but after a while it took a combo of a few of those... then (after multiple restarts) I can now open 6 programs at once and not get any freezing. I have not tried every program, but it almost seems like once I open a program once, and it crashes, that program does not cause the crash anymore.

Odd, my iMac has not had any freezing problems after a year and a half of use

Maybe I am just lucky!

and of course... just froze up on me while browsing and art website.

Much Less Freezing

Just to follow up, my iMac has only frozen up on me once since I last posted. I wonder if this is something that gets better over time, although I have not idea why that could or would happen.

Such as.. numerous software updates?

Mine used to freeze up several times a day. Returned it for another.. Did the same thing. However, with each and every software update, it seems to have got better. I can't even remember the last time it froze now

I would have thought that except that I got Leopard about 10 days ago, downloaded and installed all the upgrades available, and that is when the freezing started. There have not been any updates (save one I think - compressor?) since then.
