Hi everyone,

 

My System:

Medion Akoya x7811 laptop - Bios date 09/23/09

Win 10 Home x64

4Gb Ram

Radeon Mobility HD5870 1GB 128bit replaced with Nvidia GTX 660m 1GB 128bit

GTX 660m ID : PCI\VEN_10DE&DEV_0FD4&SUBSYS_00000000&REV_A1\4&36714C63&0&0018

 

My laptops graphic card(Radeon Mobility HD5870) stopped working about a week ago and i couldn't find the identical one locally so i found a GTX 660m and thought i'll give it a try. 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

Can you suggest any solution or maybe different cards that may work on my system? Thank you.
