Fire hazard being messing something up by tinkering with the PSU. It’s not worth it over something that can be replaced for so little money. And I think it’s just more about swap out the most likely failing component (the PSU) and see if the problem goes away. If it doesn’t then you know it wasn’t the PSU.
When this game came out I hated it because I loved the original Call of Duty games that were super slow paced and more realistic. But eventually it became my main game playing till 4am on Xbox with friends. I miss the simplicity of COD MW.
