G5 quit on me...again.

Question

So yesterday I was browsing some pages on the web when all of the sudden my FIOS connection gave out. No biggie, so I figured i'd just reboot my G5.
I rebooted and it started with the normal "chime". But when the grey apple logo screen loaded, it did with rectangular blogs and lines going horizontally. Kind of like if you ever loaded a bad Jpeg picture.
It hung and hung and finally the screen went black, fans kicked like a 747's engines and nothing else happened.
I rebooted again, this time the grey screen froze, along with the lines, and nothing happened.
Rebooted a third time and the same thing happened as the first time. Went to the black screen along with the fans.
Rebooted once more and reset my PRAM with no avail.
So I decided to just put in my Leopard DVD and just do a archive and install.
I held down the mouse so that I could eject the tray since the button on the keyboard wasn't doing it and it spun the DVD and made sounds as if it was doing something, but all I saw was that same black screen as before.
I don't know what it could be.
I did call tech support on the phone and the person did suggest that when I got home from work(which is where I am now as I post this), I should unplug everything and push the power supply reset button(I think that's what he called it) near the RAM slots. I am going to try that in a short while and will update this thread if a solution is found.
If anyone here has any suggestions on this or has had a similar problem, please let me know. I thank you in advance!
PS. Back in January, I did have the dreaded loading screen problem that many have with their G5 where you see the little file icon with the question mark. It was fixed with a quick 10 minute visit to the Apple store where a tech just basically pluged in a mac book to it and hit a couple keys and that's it.

Answer 1

Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - run Option #4 to rebuild the database.
Fix #2
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option.
4 - In the next  window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments.  However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
