Rtx 2080 rendering device lost

I have a brand new system that is certified to work correctly. However, in only overwatch I keep getting this error rendering device lost. I followed all of the troubleshooting steps online to fix the problem to no avail. I have downclocked by gpu, changed some nvidia settings and turned on debug mode. I am very upset as I just spent 3000 dollars on my computer and my game keeps crashing mid game. I was suspended for 30 minutes because of this. I am very angry right now. please fix this. It should not happen. I called EVGA and they said that they also play the game and experience the same thing. FIX IT OR ELSE I WONT PLAY AGAIN!!! STOP SAYING IT IS OUR HARDWARE!!! I SEE MANY POSTS EXACTLY LIKE MINE AND NO BLUE RESPONSES.
