Windows 10: Why does my Computer Flash and then Shutdown?

This is happening commonly and it's getting quite annoying. My computer flashes into a bunch of colors everywhere, an then the screen goes back to normal. But everything stops responding, and I have to do a force shutdown. At first I thought it was an issue with my graphics driver, but I updated it and the same thing happened an hour later. It's 100% something wrong with the computer itself. How do I fix this?

The computer shutdown itself restart?

Hi Tín,

A computer can shutdown based on the instructions given to its power settings. If you are using a laptop, there’s an option that when you are just closing a lid, it can shutdown your computer.
To ensure that we can provide the appropriate resolution to your concern, we’d like to ask you a few questions:

• What were the recent changes made on your computer before you experienced this issue?
• What troubleshooting steps have you done so far?
• What activity are you performing that may trigger to shutdown your computer?
• Can you provide us a screenshot of your power settings?
• Are you using a laptop or desktop computer?

We’re looking forward to your response.
