Sometimes when I play I get a bluescreen, with the following error-message:
Video_TDR_failure (nvkflt.sys), and then my PC restarts. There doesn't seem to be a specific cause for this (hasn't happened in a major city or a dungeon, just outside in the world).

It happened first on my laptop at around 22.8.2015. I was then running W8. I did a clean install of W10, but it still happens.
