G5 is stuck. After a Safari update, couldn't turn it off or "re-start".

Question

After downloading an update for Safari, it requires a re-start. Wouldn't do it -- ie, couldn't turn off the iMac or drag down to "restart"... so, I unplugged it and waited. No luck -- tried all the normal small things, then saw on System Preferences a place to click on restart from "start-up disk" ---but, it had a question mark on it -- did it anyway and now it's WORSE - A small world icon in a square in the middle of the screen blinking as I turn it back on -- nothing else.... just that!!!

HI,
Unfortunately, it sounds like the startup disk is failing or has failed. Try booting from your install disc.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
(In Mac OS X 10.4 or later, you must select your language first from the installer menu)
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
