Good luck then in your quest for the solution.

But one of the things which *I* would have done is to install the proper 
nVidia driver which would then at least eliminate one possible cause of 
the problem; if this did not solve the problem then you can go on and 
keep looking for the cause knowing that it is not the nVidia driver.

But then, you know best.
