As title states black screen right after launching games, no sound and cannot ALT+TAB out or ALT+ESCAPE out either. I always have to hard restart. These are the specs of my computer.

I am using iObit computer mangers for the Driver install and update as well as Mal-ware Protection. The title it happens most on are, Assassins Creed Odyssey. I have gotten it to work once before but i only was able to run the built in render test.
