Windows 10: PC crashes when in idle

Hey support,I have been getting random crashes and restarts on my PC, this usually only occurs when my PC is idle or close to idle. When it is under load like gaming, it opperates fine. When it does fail, it does not BSOD, it just freezes and then turns black and after a bit it restarts.I have replaced the PSU and tried a different GPU but still get the same issue. I have used DDU and reinstalled the GPU drivers and that did not fix the issue.Could this indicate there is something wrong with my Mobo?I have attached the minidump file to the following location on onedrive:https://1drv.ms/u/s!Asq

:)

 

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.

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
