IBook Won't Boot From ANY Optical Disk - correct forum this time sorry.

Question

My trusty old iBook circa mid 2005 is overdue for an overhaul but refuses to boot in Target disc mode or boot from any of my install disks, 10 or 10.3 or 10.4. When I choose the disk from Startup Disk it begins to reboot until the Apple screen comes up with some pixelly artifacts onscreen and it hangs. Holding the 'C' key down does nothing. Please help I need to wipe this baby clean and start from scratch.

Hey Craig,
Here's my pics of where the GPU sits from an earlier discussion:
"This is the position of the GPU on top. That bay right below is where the hard drive goes and that's it's connector lower right:

Here's a view with the heat sink in place and a ghost image of the GPU:

The spot where I'd recommend applying pressure from underneath:

and where that spot is on the lower shield:

So to access that you'd take the lower case off. Go to ifixit for that.
If that solves your problem or makes it better it will run like that for a while. If it gets worse you'd need to reball it. $79 plus shipping one way in the States."
