Do these crashes happen in any other game besides THE FINALS? Seems like this might be an issue with the game, maybe try forcing it to use DX11 (-dx11 in launch options if you're on Steam), but other than that, I'm not sure.
Seems pretty normal to me, most games run at 90%+ GPU usage.
I'm wondering if your drives are an issue. Is your system on an HDD or an SSD? You said you experience most of your issues when you're loading in or exiting the game, so one of your drives might be failing.
I would suggest checking...
That CPU might be bottle necking your GPU pretty hard, and running single channel ram at only 2666mhz is not good for gaming. I would upgrade those and see if you're still having problems, unless there is some other problem in play.
When you said you reset Windows, does that mean you fully wiped the drive and put a fresh installation of Windows on it? And installed all the drivers?
