    Dan the failure mode is not like a blown capacitor. It happens and 
the screen is cross hatched and nothing works. Then turn off the 
computer. When it comes back on it's fine again for awhile.

    If I run the good nVidia driver the problem occurs in 5 minutes or 
less. All it takes is a sudden change in picture like you get with 
Google and it crashes. So I'm sure it is a nVidia problem.
