Whan I attempt to start my G5 running 10.5, I get the message: "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." This occurs about halfway thru the startup process. I tried to start up with a system 10.4 system install disc, but it quits about halfway thru startup.

PowerMac, Mac OS X (10.4.11)
