I "fixed" the issue with a Lenovo Z710 laptop recently upgraded to Windows 10 by disabling the NVidia graphics processor since this laptop has two, Intel and NVidia. This stopped the video_tdr_failure error dead in its tracks. Before doing this radical "fix" I tried numerous fiddles with parameters of the NVidia graphics including going back to a prior version, setting TdrDelay to 4, etc without any success at all - hours f trying did not work.
The bad side-effect of no NVidia graphics is, alas, slower graphics however the positive side-effect is the system is not crashing and rebooting within seconds of starting up graphics-intensive games, etc. Until NVidia fixes their software this will simply have to do.
My daughter is now playing "Blade and Soul" in the other room where before she was just calling me when confronted with the BSOD; she is nto bothered by the slightly slower graphics of the Intel processor set.
This is a big win...sort of.
