I have a EVGA 980ti, 6700k, and am running Win10 Pro N.
Its literally a cycle when calling support.
Steam gives me obvious solutions that don't work.
Nvidia confirms that the GPU is stable and is not at fault, which I believe because all other games and programs work fine.
Microsoft does a scan on my computer and confirms that my Windows is stable.
Only logical explanation for this is a CSGO patch or something along those lines, because this post is recent too.
