I'm pretty sure i can't update a driver that is not installed at all. And i it is allowed. But, I found out that the 3D Video Controller driver is missing, and I'm trying to find it, though all the Google results are in russian for some reason.
Not all of the them have GT740m, are you sure it there? where did you bought it from?
Sorry for the late response. I took a look at dxdiag, still the Intel HD one, but the laptop model is different there compared to the stickers, which may be wrong. There it says it is a K56CM. So, maybe there is no actual nvidia card, and the stickers are wrong. God Damn stickers... Thanks
