Windows 10: Newly built PC freezes on idle or low power

I've been having an issue for the past 2 months where my PC slowly freezes up when I'm not doing very much. The only time it doesn't freeze is if I run a game in the background.

I recently thought it was due to faulty RAM as I did a scan and 1 of my sticks had errors. Since then I've replaced them however I'm still getting occasional freezing. Is there any way to find out the reason for this? I've checked Event Viewer and Reliability History but I'm unsure what to look for exactly. I have noticed many errors in Reliability History, one including 'Hardware Error'.

Windows 10 freezing during low CPU loads

Hello,

I've had a freezing problem ever since I built
this computer several months ago. The freezes only occur during low cpu usage, such as sitting idle or browsing the web. They do not occur at regular intervals — I've had freezes after letting the mouse sit for a second, and no freezes even after leaving
the computer idle for several hours.

Things I've tried to resolve this:

• Changing all Windows power options to high performance settings
  
• Setting AMD BIOS option "Power Supply Idle Control" to "Typical Current Idle"
• Resetting Windows update folders

I've checked the Event Viewer for more details but I'm not sure what to look for. Any advice on how to proceed is greatly appreciated.

Thank you for your time.
