Various Crashes

[PanzerYeena]

So I've been playing Warframe for less than a week and already I've had more crashes than I can count. The most common ones are:
 

1) Black screen: screen goes completely black, can't see a damn thing. The sound is still playing and I can hear the actions if I try to do anything but the screen only shows black. Minimizing the game and re-entering doesn't help, the only option is to shut it down via task manager (which says the game is running, btw). Has happened randomly during missions but mostly in the ship when I try to access the foundry, market, etc. 

 

2) Sudden freeze: Happened twice so far, always during a mission and always when I try to activate something (i.e. hack a console). The only option here is also the task manager, only this time is says that Warframe is not responding.

 

Any ideas on what can be done?

I'm running on Win7 Enterprise, i5 2550k (3,30GHz), EVGA GTX 980 Classified, 16GB of RAM
