I've seen exactly that logic expressed by more than one other person, only to finally weeks later have them acknowledge that a low speed burn solved their boot problems. If the disk was burnt at high speed it can be quite marginal and behave differently on different CD drives. If you did not burn this disk yourself at low speed then I suggest that you burn another copy. And in light of failsafe not booting I suspect that this is the problem.

Alternately, boot and type memtest at the boot prompt to run memtest86 and check your system memory.
