As for me, I used to have that driver error in my GPU while playing DOTA2, I thought my video card had failed (Palit 760ti jetstream 2gb), but after stress testing in 3dmark, it was ok. It occurred to me that it was the installation of the card on my Mobo that was wrong, it was a bit dislocated due to prior installation of fans in the case. So, I suggest you do clean your case, maybe overheating also, and reinstall your card physically. If does not solve it, buy a higher PSU, I have 650W. Never got the black screen error resulting to hard reset again. Witcher 3 pushed my GPU temp to 80c so I initially stop playing it since I dont have proper cooling yet on my system, then I added fans, cpu cooler and another ram stick, you know that higher temp in GPU means higher consumption of power, right? so there, PSU. :)
