The video adapter stopped responding and was restored, how to fix it?

Question

NVIDIA

"The NVIDIA Windows Kernel Mode Driver has stopped responding and has recovered."
Nvidia Geforce GTS 450, Windows 8.1. And it is not known what exactly causes it. Monitored the temperature, the load on the card. Flies out unpredictably. Sometimes it’s normal even in games where it heats and loads, and sometimes it fails with almost one conductor.
Actually. I installed old firewood, even turned off several types, deleted it, in general, I carried out all the driver frauds that were possible. TDRDelay and others like it have also been tried. I changed the paste, there is enough power. With Nvidia Inspector, I also tried to experiment with everything. And it could be blamed on the physical problems of the video card, but for some time after reinstalling the system it works fine (yes, I even tried different assemblies in addition to clean Windows).

Answer 1

I have seen this on video cards that were previously mined.
With a high probability, these are power problems, if not in the power supply, then on the video card itself
