    Imac g5 2006, no chime, some artifacts, freezing

    Hi,

    My imac g5 has just died i think ;( Bought it 2 yrs. ago with a faulty PSU and worked fine after repairing it!

    Status right now, all of a sudden:
    - no chime anymore
    - freezes with white screen
    - seeing some artefacts at the place of the Apple logo.

    When hitting the Imac a little bit, i see some pink artefacts. I tried to reflow the nVidia fx5200 ujyt322GPU, but still it isn't working.

    Does anyone recognise this problem? All three leds lighten up, butt the fact i don't hear the chime is something i can't explain?

    Question:
    - Does a failing GPU makes the chime disappear?
    - Is this the GPU that is failing?

    (Today or tomorrow i'll swap the HDD and PSU from another Imac i have to be sure they're not the problem.

    (No visible damages to the midboard capacitors. Heating them isn't the solution, so i guess they're not the problem.

    Probably the gpu, try pressing on it when it is running.
    I can put text here?!
