Recently when I was streaming call of duty cold war zombies my gpu crashed
now this is not the first time this has happened
on cyberpunk it did this, randomly happens too, really annoying me and could use some help

second yes all drivers are updated
and this was built by a guy on facebook ( I over payed sadly)
