Black Screen in-game

[hawkins109]

I'll be sitting there playing, minding my own business, but when I take off running or the shooting gets heavy my game just goes to a black screen.It will do this for up to 30 seconds or so then I can play again. However, sometimes after that black screen I get about 5 seconds before another black screen appears or up to 5 minutes. It does prevent me from playing the game, especially when my squad is moving up and I can't because the black screen freezes up the game. It also does this on my Forgotten Hope 2

I forgot to mention, both games worked fine 2 weeks ago when I last played, but now they won't
