I have looked at your first mini-dump (most recent) and it does look as if there is an issue with the NVidia drivers.
Driver details: Loaded symbol image file: nvlddmkm.sys
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is
caused by drivers that have corrupted the system pool. Run the driver
verifier against any new (or suspect) drivers, and if that doesn't turn up
the culprit, then use gflags to enable special pool.

Maybe Need for Speed has an issue with these latest drivers. Have you checked on the Need for Speed forums to see if others are having similar problems with the latest NVidia drivers?
