Till now, I have just installed the very last driver for my graphic card.
I'll give some days to see if the blue screen appears again.
I yes, I'll make Braian's suggestion.
It is curious that, even the update is for Windows 7, the file start with Windows 6.1 ¿¿¿????
Is it still not clear for me if I must install 2670838 and later 2834140 or just only 2834140
