Hello, I have a PowerPc7,1 with MacOS X Server 10.5.8, which today started freezing and restarting. After the system froze, sometimes it restarts automatically, or I have to manually reboot it with the power button. In both cases the restart also froze! The only way to start the system is the clean the PRAM, but after a while it is crashing again! I managed to run the full ASD 2.5.7 test without error for a few hours (then I stopped), and with the install DVD I also managed to run the system repair (there was nothing to repair). Both from the system and from the install DVD I cannot run the repair permissions (it freezes!). So I tried to execute "fsck -fy" from the single-user-mode, but the computer froze again! Is there something else I can try? Thanks a lot!
