    Hi guys,

    I've recently noticed that when I start my imac it displays a weird pixelated white screen. It occurs right before the log in screen and it's intermittent(Sometimes the screen startup normally). My Imac has the radeon 4670 and I have already checked if there were any firmware/software updates I needed. I have also ran the apple hardware test as well, but it did not find any issues. I've took a screenshot of the problem(flickr link). Any suggestions?

    Thanks
    Simon

    That looks weird. Should contact Apple Care to find out what's going on.
