Driver errors and probably deleted recovery partition.

Hello, I have asus x550l with dos, and i've encountered few problems that kinda worries me. First of all I formated disk that was about 20 gb big with some info in it. I've installed Win7 64 bit version and found that many drivers were missing (figures). So I started downloading them, and it was a strugle. 5-7 hours of looking for drivers, not installing. Then i found most if not all of them, installed, and got one more problem. When I try to install nvidia Gpu drivers I get an error . Device manager says that all drivers are up to date, when i try to use Intel driver utility, it just doesnt work. So now im really lost and dont know what to do. Tryed to run game (LoL), doesnt work, when I use GeForce experience, it doesnt even start. So i'm wondering if it's some missing drivers that i dont know, or i messed up windows instalation. Not sure what to do, any help would be good. I can add more screenshots if anyone is willing to help.
