nvlddmkm display driver stopped responding

I had a problem with my NVIDIA drivers, blanking my screen and turning my monitor off while some times I would get the error message the driver stopped responding and was restarted or something.

I tried everything to no end. At the end I tried two things that seemed to help the matter.

First I went into the NVIDIA control panel in the 3D settings and changed in the Global settings the Multi-display/mixed-GPU acceleration setting to Single display performance mode. That helped a bit when I was minimizing and maximizing windows, the driver was slowing down but wasn’t crashing.

Second, after a nice hard crash, I went into BIOS and change the frequency of the memory sticks to the lowest I could get, which it was 667MHz. That seemed to stabilize the system a bit more.

So far no crash, but hey you never know. LOL.

UPDATE:
Those settings didn't work at all. Screen still turning off when the error appearing. I had to use an older version of the NVIDIA drivers (186.18) to be able to actually recover from the error. Now the screen does come back on with out freezing the whole system. Is not a solution per se, but it's something. Research is still going on to find a defenetely solution.
