My eMac is coming up with a "Restart the computer" error every time I start it. I've had it for about 60 days, so clearly I'm pretty annoyed at the problem. After attempting to use the Disk Utility to repair the drive, which failed, the support technician said that the operating system is corrupted and must be reinstalled. Problem is, I have essential non-system files that I know are intact, but I have no way to back them up before the reinstall. Based on some advice, I attempted to perform an "Archive and Install." The only problem is that it doesn't give me the option to preserve "User and Network settings." I have a Windows computer and a FireWire-based external hard drive at my disposal. What can a do to get these 20 or so files safe?
