  1. PC shut down unexpectedly, now I can't adjust brightness and my game is running sluggishly


    I have a Lenovo Legion running Windows 11. Last night, I was playing Elder Scrolls Online when the game locked up, so I force closed it. Then I switched to my browser, and that froze up too, followed by the computer shutting down. I had to try three times before I could get it to start back up.This morning, I used the browser and it ran fine, but I lost the ability to adjust my screen brightness. The bar is missing from Settings, and I can't use my keyboard key to adjust it either. I followed these instructions to fix it, but it made no difference:https://appuals.com/brightness-not-working-win
