Hey guys, I recently purchased a Sager NP7258 Laptop without an OS. When I installed the OS (Windows 7 ultimate), I tried to install the drivers necessary for my laptop to work correctly. However, when I downloaded the NVIDIA Graphics Card driver, the computer detected it but it had an exclamation mark next to it in the device manager. I uninstalled it and tried to reinstall it but then the installer said that there was no compatible hardware. I then uninstalled all of my drivers and reinstalled them and the NVIDIA Graphics card driver installed, but when i restarted the computer, the computer showed the the blue screen of death and it restored it back to a time when the computer was working. I've tried uninstalling and reinstalling, but now my computer doesn't even recognize the NVIDIA graphics card anymore. My graphics card is a NVIDIA 965M 2gb. Any help will be greatly appreciated.
