[Video Freezes But Game Plays - GeForce GT 750M]

So I was playing on my PC and my game's video continues to freeze. I can still hear myself running around, shooting, and picking up items that my friends direct me to; but my game screen just completely freezes. My computer is not freezing, I can alt-tab and do other stuff; it is only the game video that freezes.

Here are my specs:
Computer: Lenovo-PC

OS: Windows 10 Home 64-bit

System Model: 20217

Processor: Intel(R) Core(TM) i7-4700MQ CPU @ 2.4GHz (8 CPUs)

Memory: 8192MB RAM

GPU: NVIDIA GeForce GT 750M (But I have 2 of them and I'm running SLI)

Please help, I am debating suicide because I'm forced to constantly play a S#&$ty game like League of Legends because I can't run this game. I have turned off every extra video feature and lowered all the details to their worse settings in the Display.
