There is no video output on laptop screen and hdmi but interestingly vga output is working. I tried every driver and modified inf in the forum to no avail. Both setup and have disk method doesn't work. The nvidia card isn't even recognized in windows. You can check GPU-Z screenshot here http://gpuz.techpowerup.com/16/04/03/uv8.png Can you suggest any solution or maybe different cards that may work on my system? Thank you.
