    My Mid 2007 aluminum iMac suddenly went bad. It started but no chime and display was totally lifeless. So i removed ati 2400 graphics card and boom! It booted well. I wonder if some one has had similar issue? Was it dead gpu or oddly behaving logic board? My assume is video card, but those are rare and expensives.

    It booted with no video card?

    Then there could not have been a display. So how did you know it was booting?

    Well, but he said "booted well." He can hardly make that assessment from the start-up chime alone.

    Actually i heard boot chime and long hdd activity. I might remember wrong, i could also control volume? I tried again but no response for volume buttons, so i assume it won't boot all the way,
