I had an issue with the G5, so I ran Disk Warrior. It fixed all the problems (or at least it appeared to), but ... when I boot the computer, the apple screen comes up and the spinning wheel, but it won't launch. It shuts off and reboots (over and over). If I hold down the shift key and boot in SAFE MODE, it works. How can I get the computer to boot without the safe mode? What gives? Any help will be appreciated.

On the Safe Boot thing...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & trash/rebuild cache files
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
