    Really need your help guys!
    Blue screen after powering
    Imac alu, SL 10.6.8

    Failed methods so far:

    -repair disk permissions via external system or install DVD, no luck
    -->message "Warning: SUID file "System/Library/CoreServices/RemoteManagement/" has been modified and will not be repaired."
    i know that Apple says the message can be ignored

    -unplugging the imac of every peripheral device as well as power cord,
    holding down the power switch for 10 sec.

    -doing p-ram reset

    -booting in safe mode, blue screen-->loading circle+blue screen--> no loading circle + blue screen---> loop phenomen

    Do have any other suggestions?
    When booting from an external hard drive, the icon of the internal hard drive on the desktop has got a lock now. Do you know what to make of that?

    Reinstall Mac OS from the disc if you have 10.6
