Computer randomly turns off then on again

Bought a new pc from techfast.

Specs: Gaming PC with RTX 3070 Ti 8GB, i5 10400F, 16GB RAM, 500GB PCIe NVMe M.2 SSD $1999 + Delivery @ Techfast

• Intel Core i5 10400F processor
  
• RTX 3070 Ti 8GB LHR graphics
  
• Gigabyte B560M DS3H motherboard
  
• 16GB 3200MHz RAM
  
• 500GB NVMe m.2 SSD
  
• 750W 80 Plus Gold PSU
  
• MAG Forge 100R Case
  

Also before crashing in event viewer it gives error with Event ID 56, ACPI 2 source from Application Popup. Before crashing from source of Kernel-Power.

When left idle just downloading things, it will randomly reboot. No BSOD, just a turn off and reboot. Turned off automatic restart, will restart regardless. Now using the computer normally, it will sometimes turn off then on again (no BSOD).

I've made it so when powered/not powered it should not go to sleep. I've tried enabling power loading in BIOS. Tried reinstalling USB drivers as I had issues with it disconnecting and reconnecting too.

How to stop is from restarting randomly when idle and downloading things?

E: I tried the memtest 86, but it reboots during that test too. Not sure what that means. Windows memory diagnostic came out fine though.

 

Bluetooth still on while idle

Thanks for following the steps. Now, the settings won't take effect if you are only using normal PC idle mode. Normal functionality of Bluetooth and Wi-Fi settings are to stay connected even if PC is idle. With the settings that you have created, we would
suggest that you set your PC to automatically go to Sleep or
Hibernate once idle. In this way, the settings "Allow the computer to turn off this device to save power" should take effect.

To set your PC to automatically go to Sleep or Hibernate when idle, please follow these steps:

• Open Control Panel, set view by: Small
  icons.
• Look for Power Options.
• Click on Change when the computer sleeps on the left pane.
• Set a timer.

Please try it out. Hope it helps. If you have any other concerns, don't hesitate to come back to us.
