Is this the error?
ID3D11Device: CreateTexture2D Failed!
Error: DXGI_Error_Device_Removed
Desc. Hardware Device Removed

That may be caused by hardware problems, since it was working fine for so long. See the topics:

DXGI ERROR Crash - turned WIN 10 conflict (reverting back to Win 8 avoided the problem)

DXGI device removed error/CreateTexture2D failed (fixed by a clean reinstall of the video drivers)
