Solve : how to change display graphics card??

1.	Solve : how to change display graphics card??
Answer» I want to change my integrated Intel HD graphics 4600 CARD for my NVIDIA 860m card so that I can use 144hz instead of 60hz. The problem is I have tried everything I can find online, like deleting drivers, CHANGING settings in nvidia controlpanel and such. When I delete my Intel driver it just reinstalls itself when I restart the computer, My LAPTOP also switch to some basic microsoft screen driver when I delete the Intel driver. Please help me, I just GOT this new monitor and it sucks that I can't use it fully.What make/model laptop?
