Why does my computer keep restarting?

Have you ever had a computer restart when you were getting ready to do something important, like work on a project? Or maybe you’ve faced your computer screen freezing or have to restart your computer a few times in a row, and you’re not sure why. Restarts can be frustrating, but they don’t have to be.

In this post, we’re going to discuss some common causes of computer restarting and how you can fix them. By following these tips, you’ll be able to get your computer back on track quickly and without any trouble. So let’s get started!

What is a Computer Restart?

A computer restart is a process in which a computer shuts down and starts up again. During the shutdown process, any open programs or applications are closed and the operating system is shut down in order to complete the restart.

Once the shutdown process is complete, the operating system boots up again and all necessary files, processes, and settings are restored.  It’s an essential part of troubleshooting when your computer starts to act up, as it can help clear out any temporary settings or files that may have been causing problems.

There are several reasons why computers may restart unexpectedly. It’s important to identify the root cause of the problem which is penned down below before jumping into solutions.

Virus Infections 

Another cause for unexpected restarts could be a virus infection on your computer. Viruses are malicious pieces of code designed to damage your system and cause various issues—one of those being repeated restarts without warning.

Hardware Compatibility Issues
