    I was trying to update my G5 to snow leopard from leopard 10.5.5 when it said it could not install. So I decided to quit installation and boot from 10.5.5. It started up and reaches the apple loading screen but goes off without reaching the log in screen. I have tried booting from the CD again and resetting the PRAM but it still wont work and continues to do the same

    G5s can't run Snow Leopard as it's a PowerPC Machine and Snow Leopard only runs on Intel Macs.

    Try booting from your retail/restore disk by holding down Alt at bootup with the disk in the drive, then you can (if you made one) restore from a Time Machine backup, or try and solve the issue with Disk Utility.
