Re: NVidia drivers crash system. Hard.
In your bug report, I see a few hundred of this warning:
ACPI: Unable to turn cooling device [c17dddec] 'on'
I'm not sure what c17ddec is, but it seems like something needs to get cooled, and is not. Are you sure that this isn't an overheating problem?
Also, what kind of motherboard are you using, and which BIOS version?
