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

    I installed the kextfix on Lion and it runs much smoother now. The animations when going in-to fullscreen and launchpad on 'vanilla' Lion where very slow. With the kext-fix the animations are much smoother now.

    Had the same problem with my iMac for a long time now. I downgraded to Leopard and waited for Lion. But when I installed Lion, I had the same problems again :-((

     

    Thank you for this thread!! It seems, that for me the kextfix works! No more freezes so far on Lion. Cool.

     

    I hope that Apple will fix the problem in an Update for Lion and we don't have to fix it for our own on each Update...

    I'd like to add another bit of data to this saga.  Mine is still freezing after 30 to 60 minutes of light usage with and without the KEXT hack, running just stock applications (itunes, ical, imail, etc).  However, I've left the machine on and running all these applications for the past week but have not touched it.  In all that time, it has not frozen.  So it appears it can run indefinitely as long as the screen isn't being actively used.  This is further evidence that the problem is related to the graphics driver...

    I got the ATI Radeon HD 4850 graphics card and it usually freezes or the screen goes black after playing for a while (World of Warcraft). If I do the kext fix am i supposed to use the ATI4800Controller.kext file from the zip file provided by KrzysiuTurek?

    At the moment there are 163.386 views on this topic, so Apple you might do something about this graphics card driver and update thingy?!?

    Well, that's the thing, I don't think they're reading these.

    Maybe if every time we have a freeze, we submitted a trouble report Apple Support they could consider paying some attention to this thread?

    I've already submitted a number of them. Whenever the system detects that it went down hard it asks and I send it with some comments...

    I just wanted to chime in too. I have a 20" iMac 7,1 and it's display has been randomly locking up for quite some time. I'm trying the kext fix too, since I've tried just about everything else. This really *****. Nice to know I'm not alone. ;-)

    Two days without a freeze! Thank you again for the kextfix! Without this thread I would have probably thrown my iMac out of the window... Lion is working perfect now... Apple, please fix the problem in the next Lion-Update!

    Thanks for the update. But I would like to point out that the kext fix is NOT working for a lot of us. I don't want apple thinking it is no longer a problem!

    Thanks. Great idea I did just that. My screen froze while I typed this and I had to start again after reboot!
