Hi,first of all this is the link you should be downloading the drivers from:
https://www.nvidia.com/en-us/drivers/results/112594/
If the seller gave u a disk,dont use it,it might be a virus.Use the link i sent u.
Can u describe the error or problem you have when u tried downloading the driver?
My intention is not to be mean here,but i just have problems understanding your english so please go to google translate and translate what you want to say from your language to english,so we can understand better what the problem is.
