random restarts

Hi Lili,

Hardware failure or system instability can cause the computer to
randomly restarts. As our initial troubleshooting step, we suggest you to run the Power troubleshooter on your computer and check if it fixes the issue. Here are the steps:

• Press Windows key.
• Type Troubleshoot.
• Under Find and fix other problems look for
  Power.
• Then Run the troubleshooter.

Update us with the outcome and if you need further assistance.

 

Random Restarts?

When I had random restarts I THINK it was my PSU that caused it but alternatively it could be a driver which needs to be found that's causing it (if it's a driver).

 

random restarts

Hi,

If a Windows computer random restarts, the device usually have some damaged system components. For us to provide an accurate solution, we would need you to answer the following questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to the device before this issue occurred?
• What troubleshooting steps was already performed to your laptop?

In the meantime, it will be best to make sure that the latest update of Windows is installed on your device. If the same issue happens after installing Windows Update, we suggest running the power troubleshooter. To do so, follow these steps:

• Open the Control Panel.
• Using the search bar at the upper-right corner, type troubleshooting.
• From the search results, click on Troubleshooting and then select System and Security.
  
• Click on Power and then follow the prompts to successfully run the tool.

We are looking forward to your response.
