2nd-Hand Mac Pro 1,1 stuck on grey Apple screen
I've just gotten my hands on a supposedly working secondhand Mac Pro 1,1.
At first there were kernel panic issues when I inserted a USB Keyboard, but that went away once I started using Apple Wireless Keyboard.
After I started installing Adobe CS5 and some other applications, there was one incident when it restarted itself, or would just take forever to boot to OS X.
Subsequently, it just refused to boot, with some luck, it gets to Safe Mode sometimes.
I've tried to isolate the issue and now it does not boot at all, it just stays on the grey screen and freezes with the turning gear.
It also has an orange flicker.
The following methods have been used to isolate the item in question:
1. Resetting SMC, PRAM and NVRAM
2. Removing all additional Hard Drives
3. Insertting a new hard drive
4. Booting up from Installation Disc - This leads to a messed up orange display on screen
5. Removing all but original factory ram
6. Removing all but 3rd party ram
7. Disconnecting all optical devices
8. Switching PCI slots for Graphic Card
9. Cleaning up the Nvidia 8800GT which apparently seems to be have overheating issues, or so I've read.
10. Moving to a space with better ventillation
The only items that I can see are not stock in the Mac Pro are the additional 1GB of RAM and the Nvidia 8800GT.
I've suspected that the issue could be the Graphic Card, but I've never thought that a graphic card could prevent a system from booting into the Operating System.
Before I spring another $200 on another graphic card, would anyone have encountered something similar and found a fix?
I'm just concerned that this could be a Logic Board failure and I've just screwed myself.
Would appreciate any help on this, thanks!

Sounds like a Hard Drive issue you have there.
I've resolved mine by changing the graphic card, works like a charm now. :)
