nvlddmkm error

Hello,

I have begun receiving a "nvlddmkm" error several times an hour. The screen will suddenly lock up and then go blank for a few seconds. After a moment it will come back and let me continue on my merry way. There is a notification balloon at the bottom right that says the system has successfully recovered from an error involving the "nvlddmkm" driver.

Many internet searches have narrowed the problem down to either Vista or Nvidia drivers or both.

I have tried many different solutions and so far no luck.

Has anyone seen this before and come up with a resolution?

Thanks,
Neeva
