Driver software for users with Nvidia graphics cards.
As an IT Support Specialist I encounter these issues all the time. First of all, update the graphics driver, it is highly recommended if your is in a blank state. Then you can follow along what others have mentioned above.

It can cause bluescreen and can be caused by failing hardware or corrupt drivers, it often crashes when playing games or watching movies, i have heard it also happens when computer waking up from sleep, seems to have a connection to dxgkrnl.sys and dxgmms1.sys, have not been able to fix it after formating ssd or configuring settings. some settings makes it crash faster than others and some games don't make it crash
I delete it since it obviously caused bsod. I did this after I did almost suggestions found in the net. My nvldmmkm bsid so far is gone
Just the nVidia driver. Necessary for nVidia Graphics Cards.
