Basically I moved to a smaller case and I tried switching out the cooler on my gpu. I messed up using the wrong spacers on the cooler and the cooler didn’t contact the gpu at all when i booted up. Now I have it in full contact with the original cooler and temps are low but whenever i try loading a game the screen just goes black. And also occasionally, like twice in 48 hours the computer has crashed when under practically no load and when rebooted, booted into a lower resolution than my 1080p monitor and when i go into settings it doesn’t even have an option to increase the resolution.
Is there anything this could be other than my GPU being damaged? Any troubleshooting I should do?
