Re: PPC Computer freezes after booting CD
Using the live cd, try hiting f6 at the screen after language selection. Use the spacebar to deselect apic and lapic and see if you can continue to boot into a live session. This isn't a definitive solution, but it worked for me on two pc's and a laptop that would otherwise freeze.
