    Hi,

    I turned my Mac onto and all I got was a white flashing light on the front.

    All the fans seem to be going.

    What would be the course of this?

    Thanks

    bring cash

    Fans running + no bong + no video + flashing power light = likely logic board failure. Could also involve one or both processors. But see Apple for an accurate diagnosis. And bring cash ... lots of cash.

    Sorry for your loss, dude. Seriously, I've been there.

    It would be covered under warranty, not sure when the OP bought their computer...

    first try re-setting PRAM. this will work on many occasions. If that doesn't work try pulling the physical ram out of the computer and re-seating them again. The flashing power light symptom is sometimes a broken motherboard but only rarely!

    Highly unlikely that there are more than a handful of G5s out there still covered by AppleCare.
