I've done every trick in the book. This problem has ONLY occured ever since I enabled the 64 bit kernel extensions on my 09 iMac (the ones that didn't ship with them enabled...). Funny thing is, the ONLY happens when I'm playing COD4. Disabling the 64 bit extensions is out of the question. I just game when I'm taking a break from Logic. These panics have been happening for the last 8 months. It's strange, I don't see anything wrong while playing COD. Temps are fine, RAM is fine (1.5-2GB free), HD is fine, cleared my cache about 3 days ago, and I run the maintenance scripts accordingly. HELP! Thanks in advanced.

iMac, Mac OS X (10.6.8)

    Looking at your KP it appears the panic starts at:


    com.nvidia.CUDA    1.1.0

    com.paceap.kext.pacesupport.snowleopard    5.8




    What are these, I'd recommend uninstalling each following the manufacturers instructions.

    An applicaiton or process doesn't need to be open in order to cause a KP, it can be out of date, corrupt, incompatible etc..


    A KP won't be caused by OS X or any of it's components however your paceap app may be out of date. I would recommend looking at your Soundflower software to see if it's to date. Also what peripherals do you have attached whent the machine Kernel  Panics? Begin removing them one by one until all are eliminated, it is possible one may be your   problem.


    In addition KP's have a frequent cause of RAM, this can be:


    Failed RAM (yes it can and does fail)

    Inocorrect RAM (suspect if you recently upgraded)

    Unseated RAM (remove and reseat)


    Finally I would recommend studying this XLab article on Kernel Panics.

    I think you just named the problem....the HD is failing. Make sure your backup is valid and if possible create a bootable backup in addition to your TM backup. Having only one backup isn't really backing up because backup HD's can fail too. But TM is better than nothing.


    I would take your machine in to be professional tested and I think you are going to find out the HD is failing and needs replacement.

    Sorry maybe I should have been more clear. KP's can be very difficult to diagnose because they can be caused by hardware or software. You noted that your HD failed verification and it's working now after it was repaired. I have seen lots of KP's caused by failing HD's. When a HD says it failed verification I have also seen that repairing them is a temporary fix. IMHO it would be wise to have the HD professionaly diagnosed. As an interim step you can also run Apple Hardware Test in Extended Mode about 3x, if it reports errors then  you know for sure it hardware. Because AHT isn't the most reliable test and doesn't always find problems after the 1st or even 3rd pass you need to run it multiple times and even then it may not find something, therefore my suggestion to have it looked at by a professional.

    Running AHT in normal mode is totally worthless, running it in extended mode once is also frequently worthless . That is why I instructed you to run it 3x. Please do that. The fans kicking in can probably be easily fixed by clicking and carefully following my instructions in iMac SMC and PRAM reset. As far as temps you need to post actual temps which you can get from iStat Pro (Google it).


    Overheating is unusual but it can happen, it normally only happens if the machine has in adequate ventilation or is operation in ambient temps heavily outside Apple's recommendations. For example if its 105 degrees F + in your room and your playing some graphics intensive gaming for hours it could overheat. However if you are playing the same games in a 80 degree F room the temps should be fine.

    Did you reset the SMC and PRAM? Another common issue for KP's is RAM related. It can be:


    Inocrrect RAM (did you recently upgrade?)

    Failed RAM (yes it can and does fail)

    Unseated RAM (remove and reseat per Apple's instructions)
