Nobody knows. There are plenty of reported workarounds for the problem(s), but not a single one that works in every case. Someone with a lot of resources and expertise available might be able to demystify the situation, but such people (or corporations) seem to be conspicuously absent.
FWIW, I'm of the opinion that it's purely a software problem not caused by nVidia's driver. So I recommend against replacing hardware or tweaking your system until it won't boot.
