[Warframe freezing computer 016]

There is an issue ive seem many people complaining about since 2015 and is not fixed yet... computer freezing forcing us to shut down the computer, it never happened in any other games before. my computer is good like every1s computer and im now wondering if is there a way to avoid it ???
already happened 17x and im getting angry from now on, ive upgraded my computer to solve the problem 2 months ago and im still facing this problem, so please dont come to me and say - is your computer! 

Ive already had same issue with
-low graphics 
-another video cards,coolers,processors,drivers etc.
-stopping every background service 
-without playing more than 2hours (it happened once after standing like 4 minutes chating in my ship right when i logged in).

i want to keep playing  
but im really out of options, i dont want to experience it again so please any suggestions?
