When I load into a game I can do everything perfectly like change settings, but when i get into a game it freezes and shows dead pixels, im assuming this is with the gpu, and sometimes my monitor displays a bunch of moving pink pixels during setup and after that, I run a rtx 2060 and a Ryzen 5 3600, sometimes when I play it shows a popup stating that stated something like you don't have the driver for CMI or CSI I forgot what it was called but it said that
