My Computer Keeps Restarting! How to Fix It? [8 Solutions]

As a regular Windows user, you might have noticed that your computer reboots randomly without any prior warning. Typically, Windows is designed to restart on its own when it encounters a Blue Screen of Death (BSOD) issue, which is beneficial for the OS itself.

However, your computer might restart abruptly without any error message, which can be frustrating since it can happen at any time, such as during important work or meetings. Some users even complain about losing data after their computers restart. Therefore, in this article, we will discuss how to fix the "random computer restarts" issue and how to recover lost data.

Reason: Why Does Your Computer Randomly Restart?

Why does my computer randomly restart Windows, or why does my computer restart by itself?

Generally, a computer randomly restarting can be caused by various factors, such as malfunctioning Automatic Restart, overheating, power issues, RAM failure, virus or malware infections, driver problems, Windows updates, and more.

Here are four main reasons why your Windows 11 computer might be restarting randomly:

• Overheating Issues: The most common reason for a computer to overheat is dust accumulation in fans or vents. Reducing internal heat can improve system performance and prevent damage to internal components, which might cause random restarts.
• Overspeeding (Overclocking): Overclocking involves running computer hardware beyond the manufacturer's specified settings. Enthusiasts can boost their system's performance by overclocking components like the CPU, GPU, and RAM. However, excessive overclocking can damage components and lead to random restarts.
• Malware Infection: Malware refers to a category of software code or programs designed to harm computer systems or their users. Almost all modern cyberattacks involve malware, which can harm your computer and cause it to restart randomly without warning.
• Outdated Timer Drivers: Outdated drivers can lead to compatibility and stability issues, reducing computer performance and causing random restarts.

Solution: How to Solve the Problem of a Computer Restarting Randomly

Now that you've read and understood the reasons behind random computer restarts, let's proceed with the eight solutions to fix this issue:

Fix 1: Disable the Automatic Restart Feature

If your Windows computer is restarting unexpectedly without any warning, you should disable the Automatic Restart feature first. In most cases, this option makes your computer restart without showing any error messages. Therefore, disabling it can help determine if random restarts are caused by an error.

Here's how to turn off the auto-restart feature:

Step 1. Open File Explorer, right-click “This PC,” and select “Properties” from the context menu.

Step 2. In the next window, click on “Advanced system settings” next to “Related settings.”

Step 4. In the “Startup and Recovery” window, uncheck the box next to “Automatically restart” under the “System failure” section. Click “OK” to save your changes.

Fix 2: Disable the Fast Startup feature

By default, your computer has Fast Startup enabled. Disabling it might prevent your computer from restarting unexpectedly. Here's how to disable Fast Startup on a Windows computer:

Step 1: Open the Windows Terminal as an administrator.

Step 2. Copy and paste the following command to disable Fast Startup:

Turn off hibernation

Fix 3: Check the power connection

If none of the above fixes solve your random restart issue, you may have a power supply problem that's causing your Windows computer to randomly restart. In that case, try replacing your old power cord or power supply unit (PSU) to see if it stops the system from restarting.

Fix 4: Update your computer's drivers

Updating your USB drivers can resolve issues with your computer randomly restarting. The driver that you access through Windows may not be the most recent, as it has to pass compatibility checks. We recommend getting the driver directly from the OEM's website.
