It might be that you could possibly have corrupted your GPU and need to re-install the drivers. And if that doesnt work, i would back up all your data to a external hdd or whatever you have and clean reset your desktop. (Also complete a thorough hardware check on the 1070 to see if there is any damage to it.) Lastly, if you still cant get videos/games to work, i would get a new card.
And one more thing actually, what BSOD error are you getting? I used to have this problem on my old laptop with a 950m. I would get video_scheduler_internal_error or something like that, and would get it from games crashing 5-10 mins after gameplay. The reset worked fine for me and i had no more issues after that
