Panic button !! from sleep to freeze

Question

Hi
I-mac G5 Power PC Tiger 10.4.11
I had a 30 minutes power failure in my house two nights ago. The mac was on sleep mode
After restarted my machine the clock was detuned at 1969 (maybe the battery ?)
later, network set-up felt down i cannot re set-up it ( maybe i have to contact my internet service ?)
Little after when the machine don't ran, the sleep mode came-in and can not wake-it by keybord or mouse nothing else than press the power button to shut down the machine.
After three times of this pattern i tried to check with the disk utility - verify-repair permissions.
Nothing. All the time i had to press the power button to come back on track.
I tried tweak freak to run something, nothing just a freezing redondance.
i went into console to run the sudo periodic daily weekly monthly et it still running since.
I have a big problem or someone's meet this..
Thank's
Dan

Hi Dan,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Then 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, reboot when it finishes.
And yes, try a new PRAM Battery.
