Welp, tried resintalling avg antivirus, it was being odd and not responding at all. No luck there. Might try a different antivirus soon

Also tried uninstalling Razer Synapse. Thinking back I got a Razer Wolverine controller around when this started happening, and I had to install that to customize the extra buttons. No luck. I doubt it's the controller itself? It's basically just a fancy xbox one controller with extra programmable buttons and some chroma light. No macros tied to it, just normal button presses in extra places.

Is there some kind of cache for Nvidia or Directx that could be clogged up over time?
