nvlddmkm.sys
I have not experienced this particular issue. But, I have experienced similiar with error message referencing NVdsp4....DLL. or something like that

3. MY solution was a total uninstall, complete cleaning of the nvidia drivers, reboot to verify totally default video and no drivers not card recognized, then install a different set of nvidia drivers. Keep track of which driver sets you try and hopefully you will locate one that does not crash.

2. You might try just a reinstall over your existing NV drivers, you might get lucky perhaps this will solve your issue.

1. You might just have a corrupt nvlddmkm.sys file. If that is the case simply extracting and overwriting the corrupt file MIGHT fix it.

Good luck and let us know what solves this for you.
