CUDA, 3D Hardware & Nvidia driver, my Blender goes crazy First I want to say that yesterday everything worked fine for me. 
Let's start.
When I launched the blender this morning, I saw this:

 

I very quickly found a solution to this problem (Blender Can&#39;t detect 3D hardware accelerated Driver), did everything as written, but now the program has begun to slow down very much. It is impossible to work.


I reinstalled blender. Did not help.
I downloaded a new driver for the video card - and oh, a miracle! - It worked! But not for long. After a couple of minutes, everything hung and again does not work.


So, right now I have 3 condition of Blender 2.79b:


do nothing = "Can't detect 3D hardware...."
download opengl32.dll = slow down, no CUDA





installed a new NVIDIA driver = everything is fine, but only the first couple of minutes, then closes and error again (about 3d) or freezing if opengl32.dll in folder .




Disconnected Intel(R) HD Graphics - did not help. What else can I do?

System Info: Windows 10 Home, x64, Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz, 16 GB, NVIDIA GeForce GTX 1050 Ti, Driver 411.70
So, the problem was in NVIDIA driver. I downloaded an earlier version of the driver(391.25 instead 411.70). I think I will not update them for a long time.
