My g4 ti keeps restarting or freezing
I have been experiencing major problems with my PowerBook g4 ti 400mhz. I sent it to PowerBook medic and the changed the logic board but it was still having problems. The tech at PowerBook medic said to reinstall the OS. I have tried that but I keep getting error messages and or the computer crashing. I have tried erasing the HArdrive to no avail. The tech at PowerBook medic said that he checked both the Hardrive and the ram and both were fine. At this point I am at a loss as what to do with it now. Any suggestions?
I would suspect a hard drive problem.
Get an external 2.5" (Ultra ATA/66 notebook hard drive or a 2.5" Ultra ATA/100 hard drive depending upon your exact model of laptop) drive in a FIREWIRE case (these models do not boot to USB external drives) and install to that.
If you can install with no problems, and boot with no problems, then swap that with the internal drive. If you can not boot and run from the optical drive that might be your problem.
