Hi, I removed all cards, put the video card back in, removed all RAM, put one RAM stick back in, removed all ATA cables exept for my startup disk, removed the battery, pushed the CUDA a couple of times for 20 seconds, pushed the power button for 20 seconds, let the thing sit for half an hour or more, put the battery back in and voilá: no more bong, the light on the power button only stays lit as long as I push it, doesn't matter how long I push it ...
So I managed to kill my MDD by following your suggestions? I'm really sad now, not even a bong left ... Jörg.
