So, my sister is having some major iBook G4 problems. The specs: iBook G4 933 Mhz, running 10.4.8 & 256MB of ram. She told me that the computer froze, she restarted & it started showing the blue screen & then went right into single user mode. I tried the logout, reboot, /sbin/fsck -fy commands & it all caused the computer to back into the cycle of blue screen-> single user mode. Any suggestions?
