Laptop BSOD (nvlddmkm.sys)

The temps you have now are not too bad, but a little high, in my opinion. I don't know what your temps are in gaming, but that is more important than idle temps. It sounds to me that with the Optimus technology, any time the graphics card is called on it crashes. Can you perform anything that uses the Nvidia graphics and does not crash?

Unless Boozad has some other suggestions, my opinion is your graphics card is not functioning. I can try a couple of other things if you want to pursue this. We could run driver verifier to see if there is some rogue driver conflicting with you card. If you want to do that I can give you instructions. But be advised there is a possibility that you may have to do a clean install, but we will take every precaution to see that does not happen.

We will continue to work with you for as long as you like until we run out of suggestions. But, it just seems to me that if your card will not even load a game, much less play it. The card seems to be bad. If it is still under warranty, I would send it back for repairs, especially since they just worked on it and it still is causing BSODs.

Don't be concerned about wasting our time. That is what we are here for. Just because I believe something to be the cause, does not mean it is actually the cause. I do not mind continuing with you if you would like to.

Driver Verifier can cause you to have to do a clean install. However we take every precaution to keep that from happening. I can tell you I have never had someone do a clean install because of it, but it is a possibility. Every thing in life is a gamble, pretty much.

Steve the only other thing I could think of trying is to force the nVidia GPU as the primary GPU and disabling the Intel graphics. My thinking being it may be the switching of the graphics that's causing the BSODs and not the card itself? It's a long shot but could be an outside possibility.

Yes, I agree. In fact, that's what I did with my laptop and it has worked well for me. However there is one thing that troubles me about that. The Nvidia card does not seem to be working at all. Although, if we uninstall it only, won't the on board be installed on next boot up?

My knowledge of switchable graphics isn't anywhere near good to say for certain Steve, I know I've read somewhere before that you can force the nVidia GPU to be the sole GPU but I don't know how you do it, and like you say if the nVidia GPU is actually borked it won't be achieving anything. I think at this point an RMA would be the best option.

You can just set the global profile in the Nvidia control panel to the Nvidia card as primary graphics adaptor. At this time I am assuming the card is borked, maybe meddy05 can shed some light on it for us.
This is how Arc said to do it, only in reverse.

First set the integrated graphics as preferred .....

1. Open Nvidia control panel.
2. Click on "Manage 3D settings".
3. Click on the button below "Preferred Graphics Processor"
4. Change it to "Integrated graphics"from the drop down menu.

5. Apply it.

Now restart the computer.


Now, disable nvidia graphics card in the device manager.

1. Click on the start button.
2. Type Device Manager in the search bar.
3. Click on the resulting link. The Device Manager window will open.
4. The third one should be "Display Adapter". Expand it by clicking on the "►" in front of it. Your nvidia card name will be shown.
5. Right click on it. Choose "Disable" in the context menu.
6. A dialog will appear with some scary words. Dont be afraid. Click on "Yes" .
7. Restart the computer.

Hopefully the nvidia display is out of use now, and so there will not be any further chance of graphics switching.
