Application has been blocked from accessing graphics hardware

I got a new system from OCUK around a month ago and have been having intermittent crashing issues when I'm in games. I'm in a game when suddenly the screen artefacts and crashes with windows giving the message:

"Display driver nvlddmkm stopped responding and has successfully recovered" or more recently

"Application has been blocked from accessing graphics hardware".

If I reboot the computer it all starts working again until the next time. It's happened in all my games at one time or another, most often in Civ6 but also WoW, Total War: Warhammer and Doom.

I've got the latest NVidia drivers but it's done it on previous versions too. Is this a software/windows issue or is my GFX card not working correctly? Thanks.

Thanks for the help. I've tried 3 and 4 and 2 doesn't apply as I haven't overclocked the CPU. Hoping it's not the first but not sure how to find out really
