Windows 10: What causes my computer to essentially shut down with powering down?

So I have had my computer for some time now but for as long as I have had it, it will randomly disconnect from my monitor and essentially shut down without powering down. The fans and lights stay on and there is no sound change with the computer, it just acts like the cable was disconnected from the monitor with black screen and no sound, then the "no hdmi connected" screen. It happens mostly while gaming, but can happen at any time. A hard restart usually fixes it but occasionally it will repeatedly do it when trying to restart. I have also tried to shut down using the keyboard and muscle mem

Internet connection causes computer to loose power.

Hello Cliff,



An outdated network adapter can be one possible reason for this.
To isolate the issue, kindly provide us these details:

• Have you made any changes on your computer prior to the issue?
• How are you connected to the internet? Is it via Ethernet cable or is it wirelessly connected?
• Have you installed the latest Windows updates?

To help us diagnose the cause of this error, we would suggest that you follow these steps:



Step 1: Boot into safe mode and check if the issue persists

Safe mode starts Windows with a minimal set of drivers and services. To boot into safe mode, kindly follow the steps on this link.



Step 2: If issue does not persist in safe mode, we suggest you to place the computer in clean boot and check which third party application driver is causing the issue.

Follow the steps on this link to
perform a clean boot.



Note: After troubleshooting, make sure to set the computer to start as usual as mentioned in Step 7 in the above KB article.



We’ll keep an eye out for your response.

The light on the power button stays on even after shut down.

Hi,

Thank you for posting your query on Microsoft Community.

As per your description, I understand that the light on the power button stays on even after shut down.

We will assist you to resolve the issue.

This issue may arise due to various reasons:

• 
  System not properly shut down or might be in sleep mode.
  
• 
  Power cord connected to the device.
  
• 
  Change in the settings.
  

I would appreciate if you could answer few questions to narrow down to the issue.

• 
  What is the make and model of the computer?
  
• 
  Did you make any recent changes to the settings?
  
• 
  Does the CPU fan spins after the shutdown?
  

As an initial troubleshooting step, (if you are using a laptop).

Unplug the charger from the lap top and check if the issue persists and also try to shut down from the lock screen.

If the issue persists, I suggest you to run the Power troubleshooter and check if it helps.

Follow these steps to run Power troubleshooter:

1. Type troubleshooting in the search bar.

2. Select Troubleshooting.

3. Select View all on the top left corner.

4. Click on Power.
