PC restarts after locking with WIN+L but seems fine with Sleep mode

HARDWARE

When I lock my PC with WIN+L and leave it for more than ~30 minutes and come back to it, it won't automatically start back up and ask for login info. It will sit there with lights coming on (in both the PC case and keyboard/mouse), but the screen won't pull up. It sits there for about a minute, then forces a restart.
This doesn't happen after putting the PC to sleep. That will start back up without issue. I've tried checking the Event Viewer to see if I could find anything helpful, but I'm not sure what could be causing this. I've included some screenshots of what I think the issue is.

I've ran a memory check to see if my RAM was messing up and that came back fine. I've updated BIOS (that was about 4 months behind) and the problems still occurs. It's been about a month or two of this issue happening.

Any advice or additional info I can provide to help alleviate this?
