Question How to stop PC from freezing when monitors wake up?

Recently my computer has been freezing after the monitors turn back on from being idle. Essentially, once I move the mouse, the screens turn on, the displays update/refresh and then in a split second they freeze forever and I need to do a hard reset. I've had a similar issue before on this computer which I fixed by disabling Nvidia G-Sync, but now it's back despite the fix. This doesn't occur immediately after the screens turn off, it happens after the screens have been off for a couple hours. Things I've tried so far, and their effect:

  1. Hybrid sleep. Still freezes, whether enabled or not.
  2. Nicehash GPU mining. Still freezes, whether enabled or not.
  3. CPU mining. Does not freeze when enabled.
  4. Using teamviewer from another PC to wake it up. Does not freeze.
  5. Setting monitors to never go to sleep. Does not freeze.

This leads me to think there's something about the CPU coming out of a powersaving state that somehow is causing this problem. Any ideas on how to better diagnose/fix the issue? I don't want to keep my monitors on 24/7, I run a plex server off this computer. Not sure if the specs are important but it's Ryzen 7 5800X, RTX 3070, 32 GB RAM. Thanks!
