Hi all, I come to this forum to seek advice on how to fix my poor laptop. As stated in the title, I have a Sager NP9150/Clevo P150EM. This laptop originally came with an AMD 7970M but it was faulty and I could never get it to work. So anyways, the replacement GPU that I was given from the person who sold this laptop to me was an Nvidia GTX 770M. We installed the GPU and that went fairly smoothly; however, the joy was lost when we got into windows. The system cannot, for lack of better words, "recognize" the gpu as Nvidia? It shows up in Device Manager as Microsoft Basic Display Adapter. In BIOS, it shows VGA: Empty. It seems like the system knows that something's there, but not what it is. I've tried the Nvidia drivers from Sager, Clevo, Nvidia themself. I even tried the first 10 and last 2 drivers from laptopvideo2go to no avail. I desperately need some advice or suggestions on this. Thanks!
