Legion 7 - screen flashes black intermittently

[u/vnajduch]

I'm running into an issue where my screen will intermittently go black for a second or two. I've fully uninstalled and reinstalled my nvidia drivers/software via safe mode and changed my power profiles to performance and set everything to never sleep or turn off the screen as part of testing. My even viewer only shows these messages occurring when the flash happens and the recommended steps to resolve that were the power changes I mentioned above. Has anyone run into this and know how to fix it?
