My fedora GUI is gone after installing NVIDIA driver

edit

Hello every body, I'm new to fedora, (Ubuntu, Linux mint user). After two months experience with fedora, I feel that my laptop is hotter that it used to be. I researched an found out, it's because of an inappropriate Graphic driver. I used this tutorial to install (I wish I had done my own solution). BTW, after installing driver v384.59 and reboot my dear fedora 26 can not provide GUI and go to command line After showing these errors:

PCIe Bus Error: Severity=Corrected, Type =Physical, Layer...

device [8086:a112] error status/mask=00000001/00002000

[0] Receiver Error (First)

I have an asus N552vw (GPU: nvidia GEFORCE GTX 960M), Currently I'm posting this question using Wnidows 10 This is myxorg.conf` file:
