I am using the same drivers. I am also told they are old but they are not.
Everyone with new nvidia drivers are getting this error.
Does you whole PC shut down and restart on it own
Did you install the card yourself
Did this start after you installed the card
I talked only the other month about a PC random rebooting.
Possible probs were:-
Power pack too small
Overheating due to a bad setted graphics card
Turned out it was a faulty card.
