Partially freezing when left to download games

[Heisenberg]

Hi, having a bit of a weird issue. Had left PC on to download cyberpunk the other night. Woke up to find my pc had partially frozen. I couldn’t move mouse but it let me bring up task manager. Also noticed time in task manager had stopped at like 4am.

Rebooted and tried again. Same thing happened when I rechecked a couple of hours later. Then tried to download a different game and this time in the morning, I could move the mouse etc but nothing would open up, download had frozen and once again the time was stopped at some point through the night. There was nothing showing in event viewer when I rebooted.

I’m currently away for the weekend but it’s bugging me haha. Any ideas what I could try? The pc seems rock solid when using it and gaming. Just seems to be when left to idle for extended time.

Anything in event viewer around 4am?

Is it zen 2 system?

What forms of sleep enabled?

Nothing in event viewer showing around the time. It’s a zen 2, 3600. Sleep disabled in windows. Unsure if there’s some bios setting though, never had a chance to dig through bios. It’s been fine since I built the system over a year ago though.
