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??

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!

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. :D

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.
