I came home one time and my primary monitor wasn't working for some reason. according to my device manager it's not working because of "code 43." I've watched videos, looked at forums, and even talked to nvidia about it. nvidia's suggestion was to reinstall my motherboards BIOS. My friends told me that could potential ruin my computer if I do it wrong. so before I try that i'm going to see if anyone knows other ways to fix that before I try that. My computer is running windows 10 just so you know.
