Roll back the driver to 314.07 and it should be fixed, I had 314.22 crash my computer 5 times, and each time same error same BSOD, its only going to be a matter of time before it effects all the games
Edit: forgot the link to Nvidia's older driver list
This error isn't a BSOD, that must be a separate issue.
It's been going on for some time but WoW causes the nvidia driver to stop responding. Windows eventually recovers (no BSOD).
It's been happening to my GTX 680 since MOP was released and that's been multiple different drivers. I'm not overclocking.
In windows 7, you can quickly end the task on WoW and reload the game, but in Windows 8 you lose all control over your desktop so you can't force close it with task manager... your only choice is to reboot, which really sucks when it happens in the middle of a raid boss.
I discovered a way to quickly close WoW in Windows 8 if anyone else is having this problem. You will need "classic shell" installed or something that adds the start button back to Win8's desktop.
1. Press windows key to bring up start menu
2. type "cmd" (without quotes) in the search field and press enter
3. Type: taskkill /im /f wow-64.exe
(change to wow.exe if you aren't running the 64bit version)
I really hope they fix this issue. nVidia and the Blizz devs need to sort this one out. It's affecting a lot of people... just go and google "wow nvidia driver responding" - it is widespread and affecting many different GPUs.
