G5, broken from last update, will not boot Leopard Disc

Question

Hello, I'd appreciate any help.
This is in regards to a Dual 2.0 Ghz G5 Powermac purchased in May of 2005.
After updating to 10.5.5, the Powermac stopped loading Leopard. The standard gray screen with the apple would turn to a blue screen, then, unlike anything its ever done before, would then change into a lighter blue blank screen, and remain blank.
I assume a reinstall of Leopard would solve the situation, but when I hold down 'c' and try to boot on the disc, it still goes into that light blue screen (still boots from the HDD).
Instead of the standard apple USB keyboard, I use a third party RF wireless keyboard. Would this prevent me from booting into the Leopard repair disc?
I don't have a USB keyboard on me, I'd have to borrow/buy one.
Anyone else have an issue like this before? The machine has been in heavy use for over three years now and it has never given me any problems.

Hi JohnnyO;
I hope you have a backup because it sounds very much like you might have lost your disk.
It is possible that your system has managed to get itself into a state where it is not capable of reading the wireless keyboard any longer. Beg, borrow or stealing one would be good idea to see if you can get any further.
If you are able to boot it from the install media that came with it, I would suggest you start with AHT to check out your hardware first.
Let us know what you find.
