Why does My Desktop keep restarting? Computer Repair Tips

Your desktop may keep restarting due to various reasons, such as software glitches, hardware issues, or overheating. To address this, start by checking for software updates and running a virus scan to rule out any malware. 

Additionally, ensure your drivers are up to date and monitor your system’s temperature to prevent overheating. If the problem persists, consider seeking professional computer repair guidance to diagnose and fix any underlying hardware issues. Regular maintenance and timely troubleshooting can help keep your desktop running smoothly and minimize unexpected restarts.

It can be really frustrating when your desktop computer restarts randomly, especially if you are working on an important work task. 

In this blog, we have listed the common reasons for this happening and how you can easily resolve these issues at home. 

Reasons Why Your Desktop Keeps Restarting

Software Glitches

One common culprit behind desktop restarting problems is software glitches. These glitches can occur for various reasons, like incompatible programs, corrupt system files, or buggy updates. 

Hardware Issues

When your desktop keeps restarting, it’s easy to blame the software, but sometimes the hardware is to blame. Faulty hardware components like a failing power supply, malfunctioning RAM, or a dying hard drive can cause your system to reboot unexpectedly. These hardware issues can be tricky to diagnose, especially if you’re not tech-savvy. 


Imagine your desktop as a bustling metropolis, with its CPU and GPU working tirelessly like busy commuters. Just like humans, these components generate heat as they work, and if they get too hot, your system can shut down or restart to prevent damage. 

Overheating can occur due to various reasons, like inadequate cooling, dust buildup, or heavy usage. To combat overheating, make sure your desktop has proper ventilation, clean out any dust regularly, and avoid running too many demanding tasks simultaneously. 

Now that you know the reasons why this happens. Let’s move on to its solutions. 

How To Fix Desktop Keeps Restarting Issue?

We have listed some tried and tested solutions recommended by computer repair experts to help resolve the desktop restarting problem. 

Disable Automatic Restart on System Failure

First things first, let’s stop that automatic restart. When your system encounters a critical error, it often restarts automatically, making it challenging to identify the problem. To disable this feature:

  • Right-click on This PC or My Computer
  • Select Properties
  • Then click on Advanced System settings 
  • Under the “Startup and Recovery” section, click ‘Settings.’
  • Uncheck the box next to restart automatically
  • Click OK to save your changes.

Examine the Power Outlet

Before delving deeper into your desktop, let’s rule out the simplest culprit: the power outlet. Ensure that the outlet your desktop is plugged into is working correctly by plugging in another device or using a different outlet.

Check the Power Cord and Its Connection

Next, let’s inspect the power cord and its connection to your desktop. Make sure the power cord is securely plugged into both your desktop and the power outlet. If the cord appears damaged or frayed, consider replacing it with a new one.

Run Windows Update

Outdated software can sometimes cause your desktop to behave erratically. To ensure your system is running smoothly, run Windows Update to install any available updates. To do this:

  • Go to Settings
  • Click on Update & Security
  • Select Windows Update
  • Click on Check for updates.
  • Follow the prompts to install any updates found.

Install Anti-virus Software

Viruses and malware can wreak havoc on your desktop, causing it to restart unexpectedly. Protect your system by installing reputable anti-virus software and performing a thorough scan. Consider options like Avast, Norton, or McAfee, and regularly update your virus definitions to stay protected against the latest threats.
