I have to be honest with you and tell you that I have a problem with my iMac computer. I'm a big fan of Apple products, especially Mac computers. I live in Bosnia and Herzegovina, where there is no Apple store, and that's why I bought my iMac computer in Croatia that was used that had a "kernel panic" error. After several failed attempts I managed to install "hazard OSX Snow Leopard" and the computer boots up normally but when it goes to shutdown freezes and shows "kernel panic" and says "you need to restart your computer." When I installed OSX everything is working normally, but I have no sound, the computer continues to shutdown shows "kernel panic" or "system uptime in nanoseconds ..." freeze. I bought the original OSX Snow Leopard DVD because I want to have a legal iMac computer and legal software on it. When i try to boot from original "OSX Snow Leopard" i get "kernel panic" fast after Apple logo appears. I try other discs but i get same problem. I try reset pram, nvram, SMC, i try another HDD and no help. I bought 2 original memory sticks  2x2Gb in Germany and when i put one or both , turn on Imac but no startup chime and no picture.


Please help me solve this problem. thanks


My iMac computer configuration is:

6.1 iMac 2.33 GHz Intel Core Duo 24 "White

S.N. W8******VGP

Memory: 3GB, 667 MHz DDR2 SDRAM

OSX Snow Leopard 10.6.2

    Kernel panics are normally, but not always, caused by hardware, with memory the leading cause.  A good memory test program is rember, which you might want to let run overnight.


    If you have the original OS X DVDs that shipped with the iMac, you should run the Apple hardware test. Find the DVD that says, in small print on the label "AHT Version x.x". Insert and boot holding the alt/option key down. Choose the Apple hardware test, and when prompted choose the extended test, which can take over an hour to run. Does it identify any hardware issues? TechTool Pro can do similar testing.

    TechTool Pro, with link above, is another program that can do hardware testing, and can be downloaded.  It can do other tasks, too. It's not an Apple program, however, it's an alternative. The Apple hardware test is only available on the original OS X disks that come with each Apple system.

    i bought Imac without any CD-DVD.


    Macs are not suppose to be sold to anyone w/o the DVDs that originally came w/it.  The seller broke Apple's licence agreement when they did so.


    You will need to determine first which OS system was originally pre-installed on your model iMac.  Check out KB Articles: Mac OS X versions (builds) for computers & Don't install a version of Mac OS X earlier than that which came with your Mac.


    You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.


    If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those -  Another resource:  International Support Phone #s.

    Your English is more than acceptable, in fact better than many here that only speak Enlish!


    Glad to see the great help you're getting here!

    Again, you will need to get replacement system CDs from the info and/or links which I previously provided for you.  The troubleshooting utilities are on these CDs.  Actually the main ones are on CD #1.

    Just so you are aware, system discs are machine specific.  You cannot use from one Mac to another.  There is nothing more to be done until you get those CDs.  After you do, post back for further instructions.


    Your other alternative is to locate an AASP near you:
