    Hi

    I am having a problem with a new (6 months) iMac.

    Spec. iMac 7,1 24" display, ATI Radeon HD2600. OSX 10.5 fully updated

    It periodically 'crashes' where a random pattern of colors covers the display or active window, see attached picture. The computer is still responsive at this point and I can usually navigate to restart the computer which 'solves' the problem. Any help diagnosing the problem would be greatly appreciated.

    Thanks,
    Aron

    That's either the video driver or there's something wrong with the video hardware itself. I'd give Apple a call.

    graphics crash that creates jumble colors on screen

    I am having the same problem on my iMac (Intel Core Duo 1.83GHz, early 2006). I have the RadonX1600 Graphics processor. Ether the hole screen or only part of the screen will get jumbled.

    In the screen shot you will see what is suppose to be iWork's Pages application. You can see the fonts and colors buttons skewed across the screen. I talked to a mac Genius at the Apple store, he said it was the graphics processor and that he would replace the entire logic board for free, I love :apple:, they stand behind there products! The only problem is that the problem still occurs when using particular programs such as "AppCleaner" (http://www.freemacsoft.net/). I'm not sure what to do, apple suggested they replace the ribbon cable between the GPU and the display but I really doubt that is the problem. So, any suggestions:confused:?

    solution, for me at least

    I have decided that the app "AppCleaner" is causing the problem. As long as I don't leave that program open for a long time, I haven't had a problem scene.

    I'd take a guess that it's a driver/software issue and not necessarily caused by a hardware problem simply by virtue of the fact that you can take a screenshot of it.

    I have something a little similar with my 15" 2.2ghz MacBook pro. I posted about it here:
    Reload this Page MacBook Pro shutting off after logic board replacement

    Here's the info again:

    I recently had an issue where my MacBook pro wouldn't start up - it just kept chiming. I sent it into Applecare and they replaced the logic board. I received it last Wednesday from Apple.

    But now, increasingly often, when I turn the computer on from sleep, the computer seems to be in a crashed state. I can move the mouse around but nothing is reacting when I click. And there is always some sort of blocky pixelation across the screen. I can shake the computer a bit and then have it go dark on me and then come back. I've attached pictures of what I'm talking about here
