Unplayable FPS on Overwatch epic with gtx 1070

[jinx9815]

I just completed my new build and purchased Overwatch. My build has a water cooled i7 4790k, 16 gab of ram, a 120 go ssd and, a gtx 1070. The problem is when I launch Overwatch with the optimized nvidia settings it gives me no problem until I try to use my keyboard ingame to move, etc. After that the game gets super studdery or just freezes. The other thing is that sometimes the PC has messages like Windows Task Manager has stopped working, etc. Please help 🙁

What are your temps?

My cpu sits at around 60c and gpu at around 50 but, according to my software they are not going to 100% load.
