PC restarting on its own

I shut my desktop and printer off last night because of storm forecast. After shutting down I walked by and noticed my computer was on. So I shut it down again and this time waited for it to go black. I thought it had shut down. I came in this morning to start it and discovered it was already on.

Can anyone help me with why this is happening and what I can do about it?

Hello Benjamin,

To see if any other Third party software is causing the issue, I suggest you to perform the below troubleshooting steps and check.

Method 1: Run System Maintenance Troubleshooter

Follow the steps given below:

• 
  Type Troubleshooting in the Search box from the desktop.

  Select the Troubleshooting option.

  Select View All option and select the
  System Maintenance.
  
• 
  Click on Next to perform the System Maintenance troubleshooter and follow the steps.
  

Method 2: If the issue still persists then,

Step 1: Start computer in safe mode.

• 
  Type Settings in the search box on the desktop, select
  Settings.
  
• 
  Here select Change pc settings and then
  General.
  
• 
  Scroll down to Advanced startup, click
  Restart now.
  
• 
  Click on Troubleshoot, Advanced options, and Startup Settings.
  
• 
  Click Restart, select Safe mode and then press
  Enter.
  

Step 2: Perform Clean boot to avoid any third party software conflict.
