i will try to explain. when i press the ALT button for choosing bootin system there is no any picture comes, i meant white screen appears but there is no any menu_icon on screen. but mouse is there! when i try to open it in target mode there is no any firewire icon on screen <only white screen>. im trying to open it from DVD with C key not booting! im trying to open it from another intel 24 inch imac but nothing happens. i tried to open it with alt+option+shift+back_delete even this command not worked.
is there any other command that i dont know? why icon menus not appear???
is there any software or any other stuff to solve this problem?

hello
did you try to install bootcamp on your iMac24"?
if yes did it went till the end?
if you did not attempt to install BootCamp and that your iMac is still having such behavior, I would recommande the reset PRAM and other standart procedure to service it (described on Apple Suppport website). You might also call Apple Support hot line as it is free the first 90 days.
