FYI i am not a mac expert by any means.
The screen is totally black but you can see the desktop in the background.
now if i unplugged it for a extended period of time the mac will boot up no problems but as soon as i restart it/ turn off and try to start if up again it goes right back in to the black screen.
All the sounds seem number on bootup.
i have tried to hold down the power for 10 secs to shutdown , then unplugged power cable and hold power for 5 secs. (read this some where)
any other ideas?
Btw i think it is a imac g5
