Monitors lose connection mid game

Hello,

So I recently upgraded to a 144hz monitor as my primary monitor in a dual monitor setup. While playing Overwatch I suddenly lose connection to both monitors and they shut down, requiring me to hard reset my PC.

My Drivers are all currently up to date, I have checked and changed my cables, I am not overclocked or over heating.

Also where do I post DxDiag and MSInfo?

Any help would be appreciated thank you!
