I had the same problem on my Dell XPS M1210 Laptop and found that disabling
the "Windows Event Log" service solved the problem. Perhaps the new version
of NVDIDA drivers has a bug associated with event logging. Anyway for now
disabling this non-essential service seems to work... I figure something else
will crop up soon.

I'm running NVIDIA Ge Force Go 7400 with the version 7.15.10.9746 driver
from Dell.
