Q: 24" iMac Screen Freezes since 10.6.3 update - pls help!

I don't know if this is just coincidence or not, but since updating my iMac to 10.6.3 it keeps on crashing. On 3 separate occasions today, whilst using my Mac the screen has gone completely black with thin white lines down it.....see pic below:

The fans and hard disk are still running but it will not respond to any keyboard or mouse presses - I simply have to turn it off by holding the power button in.
It will then restart as usual.

Anyone got any ideas? Do you think that if I was to re-install Mac OS X from my original install disk it could solve the issue?

Thanks

Darren

    What version numbers are you seeing on your now in-use kexts? Mine updated to 1.6.26.31 (9206), created and modified on Jan 20, 2011. The ones I had from 10.6.2 were v. 1.6.6.25 (7429), created/modified on Nov 3,2009. The ones they replaced, in 10.6.6, were v. 1.6.26.22 (8901), created and modified on Jan 15, 2011.

    If your updated ones were modified on Jan 28,2011, it looks like you've ended up with a (slightly) more recent version than I ended up with. I used the 10.6.7 combo updater--did you use the delta?

    hmm interesting. After looking at the kext file (ATI2400Controller) it says it was last modified Friday, January 28, 2011. I THINK that's when I replaced the file so that means that I'm running the old files still. But what I said before still stands. I have noticed great improvements in performance. Weird!

    I'm not saying the problem is fixed, I'm just saying that SO FAR my mac has been fine.

    Not fixed.

    After about 24 hours of being on, I was just listening to some music and out of nowhere, the freeze with vertical lines appeared. (see: http://cl.ly/1K1J1V1R1g0L2Y2i051s/photo.JPG )

    Sad.

    So you applied the kext fix to get yourself to a stable 10.6.6, then upgraded to 10.6.7 as you normally would...and haven't experienced a freeze yet?

    Following up on my earlier post about experiencing a screen freeze a few hours after updating a kext-fixed 10.6.6 to 10.6.7: I said I'd give it another day. I've actually given it 2+, since I made it through the next two days freeze-free. Was starting to think that maybe the new kexts just needed time to "break in" (and yeah, I know how dumb that sounds, but hey). But now today I've just had two freezes in the span of a few hours. That's enough, I'm done. When the kext fix was first posted, it was such a relief to finally quit holding my breath wondering what I'd be in the middle of working on when the next freeze hit. I'm reinstalling the 10.6.2 kexts.

    An additional comment on temperatures: we're having an abnormally cool spring, and since I live with a wooly mammoth (aka Malamute), I keep my thermostat set low. So I've not been seeing high temps on my iMac. And this last freeze happened near the low end of the usual range, shortly after the iMac had idle for a couple hours while I was at a meeting.

    Just had my first freeze on 10.6.7. Previously I had updated my graphics kext files to get 10.6.6 working. Looks like I'll have to do that again in 10.6.7. Apple still didn't fix it

    THANK YOU VERY MUCH/___sbsstatic___/migration-images/migration-img-not-avail.png/___sbsstatic_ __/migration-images/migration-img-not-avail.png

    The maclover1029 patch (in page 28 of this thread) solved my frezees

    ps: It's necesary to apply the patch again after 10.6.7 update

    Just adding my name to the list. Having screen freezes on 10.6.6 and 10.6.7

    Will try the fix tonight but it would be nice if Apple would release a sanctioned fix.

    I have also reported this to apple (everyone else has right?)

    @joemaurice:

    *I have also reported to Apple. I think that everyone should do it too.*
    *I have also pasted the link to this thread (even though they probably don't read it)...*

    *I will keep reporting to Apple UNTIL they release a FIX!*

    I just spoke with the folks at AppleCare (Tier 1 and then Tier 2), and sent off full log files and a detailed description of the issue. I will hear back from my Tier 2 agent next week after he receives a response from Engineering.

    Full disclosure: I am an Apple Certified Technician, and provided my certification ID (along with GSX sold-to ID) to the agent I spoke with. I was very detailed in the issue, and I HOPE this will provide some gravity and drive some focus to this issue.

    If/when I hear back, and assuming the information I hear isn't subject to non-disclosure, I'll post what was said, if anyone is interested. Hang in there, guys. I love my iMac and am hoping for a fix, too.

    Meanwhile, I'll be using the kext replacement (10.6.2 version), and I recommend you do the same, if you're comfortable doing so. Understand that this recommendation is in no way approved, tested, or condoned by Apple. I'm not affiliated with Apple in any direct way and am only speaking for myself.

    regarding the fix on page 28 of this thread, my Imac has an Nvidia geforce gt130 card, does any one have the drivers for this.

    IN the Zip file it appears to only be ATI drivers
