I have an Sager NP8672 with an i7-4720HQ, GTX 980M and 32 GB Ram with Windows 7 installed. Every time I would try to do something that is graphically intensive, this requires my laptop to switch GPU from my integrated graphics to dedicated graphics. As a result. I get the BSOD witht the nvlddmkm.sys error. The programs will start after i uninstalled the drivers and install the same drivers. I used the latest nvidia drivers. I have tried regedit TdrDelay. The GPU is not overheating. I have tried fresh installing Nvidia's drivers and software. There is no disable integrated graphic in the BIOS. I'm in pretty dire need of help because I'm an engineering student that needs a laptop with dedicated gpu.
