    Hi I have a powerbook g4 1.67 17" High res, and I have a problem with my computer freezing. I have to reboot it, but when I reboot it, it doesn't post and searches for a disk in the superdrive. The only way I can get it to work again is by forcing it into open firmware, reset everything, then install leopard onto it again. I've had to do this twice now, with 2 different sets of memory: 2x512 and 2x1gb. Could it be a hard drive problem, or is it the logic board? I also ran apple service diagnostics and hardware tests. Everything checked out fine.

    when it freezes try this next time (to see if it's harddrive)

    reboot
    when you hear bong sound hold down command and s (this will put system into single user mode)
    hold until you see some text
    then type this fsck -y (with space between k and -)
    sit back it could take some time
    if no problems it will say "Disk X appears to be OK"
    if it finds problems it modify above statement..thus keep running fsck -y until says disk is ok
    reboot

    may have to force it fsck -f
