I have been running some CUDA code on my GTX 960m GPU. Once I got an error saying that the display driver stopped working and has recovered. Will that create any problem or issues to my graphic card?

    It's more than likely just your OS responding to an unresponsive graphics driver. Are you doing a lot of work in a single kernel? If the GPU is busy for a long period of time (about 5 seconds if I recall correctly) the OS will interrupt it and try to recover from what it thinks is a problem. P.s. if this also happens when not running CUDA, look into update your Intel HD graphics chip drivers. I have had a similar issue occur there when browsing Youtube in Chrome for example. – Bart Apr 08 '16 at 06:46

    That's a common problem, and AFAIK can have 2 reasons: 1. It might be that there's a bug in your kernel (accessing invalid memory regions or so). 2. It might be that the kernel simply takes more than 2 seconds to compute. Have a look at https://devtalk.nvidia.com/default/topic/459869/-quot-display-driver-stopped-responding-and-has-recovered-quot-wddm-timeout-detection-and-recovery-/ . It should in no case cause any problems to your graphics card. (If the card is too busy and not cooled properly, it may overheat etc, but this is *unrelated* to this error message). – Marco13 Apr 08 '16 at 09:22
  • The watchdog reset mechanism is intended to stop situations where a PC becomes unresponsive because a user process won't yield the GPU and the display (and eventually everything else) freezes for long periods. It is not harmful otherwise. The answer really a duplicate of a number of older questions, so I have closed it as a duplicate of one of those. – talonmies Apr 09 '16 at 10:16
