    Hi there. My friend has the 24" white, 2.16Ghz iMac - spec:

    http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-24-inch-specs.html

    He is currently running a fully updated install of Tiger, and running EyeTV v2.5.3 and VLC (unknown version). Here are the problems being exhibited:

    1/ When EyeTV is running, it will sporadically, and unpredictably, crash without explanation.

    2/ Many times, the iMac will not even boot - it gets so far @ the grey screen, and then the "Please restart your computer" screen pops up:

    3/ Also, when using either VLC or EyeTV, sometimes there are patterns of green *horizontal* lines, spanning the area of the video playback window (NOT the entire iMac screen) - this happens a LOT.

    I have booted in safe mode, verified the volume in Disk Utility, repaired permissions, and it still exhibits these same issues. Also, EyeTV will freeze when displaying video, quite often.

    Before I waste any time pursuing graphics updates, or wiping and upgrading to Snow Leopard for my friend, I am wondering if this is an issue experienced by anyone else with this model?. Google throws up a LOT of "green line" results, but I wanted to be extremely specific, to narrow this down a little.

    I do hope this is not a job for Apple repair - is there anything which I may do to eliminate certain things?.

    Many thanks!

    your graphics card or motherboard has died. Its cheaper to fix the 24" as it has a removable card, but it could be the motherboard too. 1000's of people owning the white 2.16 imac have had the same
    failure, mine happened 1 month after 12 month warranty run out.

    People are clubbing together to try and get a law suit against apple, as the number of machines effected seems to be epidemic!

    Here's a link

    Try installing smc fan control as a temporary measure. run the fans at full speed as the crashes seem to be related to the temperature of the chips/board.
