    Hey guys,
    weird thing happend on my iMac. I was playing a game via CrossOver games and suddenly my screen changed to green... I had to restart the computer and now it boots, desktop shows and 'Warning about unexpected quit of kernel' shows. If I leave it, nothing happens. But if I make anything (I open Safari for example), after 20 seconds - blank white screen shows. If I tried to shut down computer in those 20 seconds - blank white screen. If I tried to boot system from DVD - it shows the booting screen and then - white or black screen...

    I run detailed hardware test - no trouble found...
    Safemod is not running, single user mode is running. I tried to repair disk with fsck -fy - didnt help...

    Do you think that there is still something wrong with hardware?
    Or how can I formate my HD via command line? Command line diskutility is not working...

    I use latest Leopard update...

    Thanks and sorry for my english...
