Thank you for posting on HP Forums, MKazi is at your service. 


I understand that you have an HP Slimline 270-a011 Desktop PC and it randomly restarts. I'll be glad to assist you with this case.


I would like to know the following information to assist you better:

  • Did any software changes or updates happen after which this issue may have started?
  • Does the PC overheat?
  • Does the PC restart while working on something specific or no matter what you're working on, it still restarts?

While you respond to that. I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

  • Shutdown the PC.
  • Disconnect all the devices and cables from the PC (including the power cable).
  • Press and hold the power button on the PC for 10 seconds and then release it.
  • Reconnect the keyboard, mouse, monitor and the power cord and power on the PC.

Please follow these steps to disable the Automatically restart option:

  1. In Windows, search for and open View advanced system settings.

  2. Click Settings in the Startup and Recovery section.

    Figure : System Properties window

    System Properties window
  3. Remove the check mark next to Automatically restart under System Failure, then click OK.

    Figure : Automatically restart check box

    Location of the Automatically restart check box
  4. Restart the computer.

       NOTE: The computer no longer restarts automatically when a problem occurs. Instead, a blue screen appears with more useful information. You can now search for a resolution using the information in the error.

    In case the issue still persists then let us check if the laptop restarts in the BIOS. The following steps will help:

    1. Shutdown the PC.

    2. Power on the PC and immediately hit the f10 key repeatedly (7-8 times) on he keyboard.

    3. The PC should display the BIOS screen. 

    4. Let the PC remain in the BIOS screen for sometime and you may check if it restarts. If it restarts then it points towards a hardware issue.


    Hope this information helps. Let me know how it goes. I'll be glad to help.


    Cheers! 🙂
