    Hi all,

    I've done as much research as I could before posting, but no luck. I have a G5 tower that has a strange pixelated screen and freezes while trying to get past the grey loading screen.

    When I try to do a safe boot, it takes me a bit further:

    When I hold down V, this is the code I get up until it akes me to the pixelated grey screen and freezes

    When I try to boot off the install disc, I can choose the disc but it once again freezes while at the grey loader screen.

    Any ideas? Thank you so much!

    Sorry, not G5, Mac Pro I mean.

    4 years old or so.

    Solved

    I chanced it and went out and bought a new video card. That did it!

    Did you try reseating the old video card? I'd imagine that could have been a culprit too.


    BTW: Wrong forum, this is Mac Pro, G5 = PPC.
