Why do computers reboot at random? If this issue has ever arisen, your computer is not the only one. It’s a common problem that both users and technicians may find frustrating. Fortunately, there are some things you can do to address the issue or at the very least make it less frequent.
We’ll talk about the causes of computer restarts, how to pinpoint the issue, and what you can do to stop them from happening again in the future.
I’ll go over some of the most typical reasons for a PC to restart unexpectedly in this guide, along with solutions.
How Do You Fix a Computer Randomly Restarts Without Blue Screen Error
A computer may restart at random for a variety of reasons, including malware, power problems, or just hardware failure in general. With some straightforward troubleshooting, you can quickly identify the cause of this problem.
1- Boot Into Safe Mode
Your computer could restart with a blue screen error for a number of reasons. You should attempt to boot into Safe Mode first to see if the random restarts continue there. If they don’t, the issue is likely not with your hardware but rather with Windows or another program on your computer.
When a computer starts up in Safe Mode, the bare minimum set of drivers and services are loaded.
To access the safe Mode, try the following steps.
- Go to Start Menu and Press the gear symbol on the left ribbon. It will open the Windows Settings.
- Scroll down and locate “Update and Security.”
- From there, you can select “Recovery” on the left panel.
- Now, press “Restart Now” on the “Advanced Startup” section.
- A new screen will appear. Select “Troubleshoot,” “Advanced,” and then “Startup Settings.”
- Now, you can press the F4 key to choose the “Safe Mode.”
- Restart your PC.
There are several reasons why your computer might restart with a blue screen error. To see if the erratic restarts stop there, try to boot into Safe Mode first. If they don’t, the problem is probably with Windows rather than your hardware.
2- Rollback to Previous Windows Update Settings (If you recently updated)
Your computer may have restarted at random after you recently installed a new Windows update. By selecting “Recovery” under Boot Into Safe Mode in Settings, you can undo your updates.
Alternately, you can access the settings and undo the most recent update using Windows Update Settings..
3- Remove Newly Installed Softwares, Programs, or Drivers
Your PC may occasionally restart at random when you install new software or drivers.
Before noticing the problem, if you recently installed a programme, it might be connected and needs to be uninstalled from your system. Check to see if removing this software works first.
This issue might also be caused by incorrectly developed drivers for your computer’s hardware components. In Device Manager, these are frequently distinguished by an exclamation point next to their names.
To automatically update and fix all hardware devices so that your drivers are up to date, use the built-in Windows tool or third-party software such as Driver Talent. If necessary, the latter has a feature for updating out-of-date drivers.
To remove programs from your PC, follow these steps.
- First, go to your Control Panel and select “Programs and Features.”
- From there, you can find your newly installed software/ program and Uninstall it.
To roll back newly installed drivers, follow these steps.
- First, go to your “Device Manager” by typing it in the Windows Search Bar.
- From there, Double-click your device with newly installed drivers.
- You can go to the “Drivers” tab and select Roll Back to the previous version.
Now, restart your PC after the removal is complete.
It should no longer restart randomly with any amount of frequency when using Windows in a normal mode.
4- Turn Off Auto Restart From Settings
Occasionally, when you install new software or drivers, your PC might randomly restart.
If you recently installed a programme, it may be connected to the issue and needs to be uninstalled from your system before you can fix it. First, see if uninstalling this software is successful.
This problem could also be the cause
- Navigate to “This PC” or “My Computer” and right-click to select “Properties.
- From there, you can find “Advanced System Settings.” Click on it, and a new window will appear.
- Go to the “Advanced” tab there and click “Settings” below “Setup and Recovery.”
- There, you have to find “Automatically Restart” and check the checkbox.
- Click “OK” to save the settings.
Note: If you’re having trouble finding it, look below the “System Failure” section for the “Automatically Restart option.”
It is one of the issues that could force an automatic restart of your system. However, you must first determine if this approach is effective for you.
5- Scan for Virus or Malware
Your computer may occasionally restart at random when it’s infected with malware or a virus. To check for viruses and malware, you can use the built-in Windows tool or third-party programmes like Malwarebytes or Avast Antivirus.
Your system files may be damaged by malware or avast anti virus, which is why your PC keeps restarting. Your computer may have been infected with the virus or malware if it cannot be removed using the built-in Windows tools. In this case, reinstalling Windows may be necessary as a more sophisticated solution.
6- Update Your Drivers and Windows
If you are unable to find a solution for this issue, or if it appears to be limited to a few specific programmes, updating your drivers may help.
It would be beneficial if you used Windows Update or Driver Talent Pro to update all of your crucial hardware parts, such as sound and graphics cards, which are known to cause erroneous PC restarts when out of date.
You might occasionally need to update your OS to the newest version.
Faulty or outdated drivers are one of the most frequent causes of automatic PC restarts in Windows 10, so updating them should help you fix this issue.
To update your driver, take the following actions: Go to “Device Manager” first. If you type it into the Windows search bar and it comes up, click on it. Then choose every device that has a yellow exclamation point next to its name.
Choose the Update Driver Software option by performing a right-click on each one. Now, wait until it’s finished. You must only install drivers that you have downloaded from the manufacturer’s website because any others could be infected.
7- Disable Fast Startup
Windows has a feature called fast Startup that enables your computer to boot up more quickly after being shut down.
When shutting down particular programmes or carrying out certain tasks that change important files on your PC, the system could crash and restart at random.
Follow these steps to stop your computer from using Fast Startup: You must first locate “Power Options” in your Control Panel. Additionally, you can find it by using the search bar and entering “Power Options.” Choose “Choose what the power buttons do” from there, then click the blue link that says “Change settings that are not available right now.”
In the “Shutdown Settings,” look for the “Fast Startup” option and uncheck it. Save your changes after that, and restart your computer to check if the problem hasn’t been resolved.
8- Update Your BIOS
Your PC cannot function without the BIOS, which is a necessary component. You might encounter erratic restarts if the BIOS has any bugs or problems.
Your BIOS update may be able to help you with this issue. First, visit the website of the company that made your computer or motherboard and free download the most recent version. Search on Google using the term “Flash Update,” as it may occasionally go by that name.
Changing the version of your BIOS is a fairly easy process. You must boot from the BIOS after restarting your computer and press the F12 or Delete key to enter “BIOS Setup Utility” mode. Choose the location where you downloaded the new BIOS version, install it, then save changes and quit the programme by clicking the OK/Exit button.
Nevertheless, depending on the model of your Motherboard, the process might be different.

Check The Temperatures of Hardware Components
To prevent PC restarts caused by overheating problems, try checking the temperatures of the CPU, graphics card, and other hardware components using the appropriate software.
This will assist you in identifying any cooling system issues as well as any internal components that might spontaneously reboot if they overheat while working hard on demanding tasks like gaming, etc.
You can test and enhance your cooling system by reading our guide on PC Airflow Configurations.
Your system might restart as a preventative measure if the temperature of your CPU or GPU reaches the limits.
In that situation, there is no need to panic. Instead, if you are an experienced user, regularly check the device’s temperature. You can also find a tonne of free software for this task on Google, and after installing it, it will help you determine whether overheating is the cause or not of sporadic PC restarts.
Try adding more fans underneath the hood through openings at your Motherboard’s rear panel if the temperatures of your hardware components do rise to the point where they start to overheat and cause system crashes. and raise it by the number of fan connectors that each component has.
Before starting the computer, make sure that the power is connected. You’ll experience computer issues if there is no cooling. Despite filters on all air vents, which prevent warm air from escaping outside, the computer occasionally reboots or abruptly shuts down.
Check Your Power Supply Unit’s Compatibility
Lack of power supply resulting from improper hardware component compatibility is the final reason for a PC to restart randomly.
Check your PSU’s wattage rating to see if it can support all of the connected components, as this can sometimes cause system crashes when shutting down if voltage limits are exceeded.
According to the manufacturer’s recommendations, replacing a 450W unit with a newer one that has two hard drives, one graphics card, and higher-end gaming rigs will require a minimum of 550W more power.
Additionally, because new graphic cards tend to use significantly more electricity than older ones did, check to see that when they leave the factory, their peak load requirement does not exceed the cap set by a particular brand name; otherwise, the computer may restart at random times when you press the shutdown button.
Additionally, make sure your PSU is in working order. This helps prevent sporadic PC restarts due to power issues later on if it just fails to function for a while after installing a replacement. Old PSUs often wear out over time and require replacement, which can occasionally cause system crashes while shutting down.
These are the likely causes of your computer’s random restarts in the absence of any warning messages, despite the fact that the voltage of your RAMs matches that of your motherboard during startup under the BIOS Setup Utility section whenever they were recently changed.
Remove the thermal paste’s cover to check that it has been applied neatly between the fan heatsink and CPU. By blowing warm air on all sides of the heatsink with a compressed gas duster for PCs or an electric fan if it’s too hot to touch, it will prevent overheating problems.
Can CPU Cause Random Restarts?
A CPU can randomly restart your system in a variety of ways. A restart may be necessary, for instance, if your CPU reaches its processing capacity and an error happens. Your CPU can also restart if it reaches its temperature limit to prevent heat-related damage.
With my new PC builds, I frequently encountered these problems. That is as a result of improper cooling system configuration. Additionally, to prevent any hardware damage that could be brought on by overheating, a CPU will randomly crash or restart when it reaches the temperature limit.
So, if you’re having the same problem, I’d suggest setting up your cooling system correctly.
Additionally, it is crucial that you regularly update or upgrade your CPU drivers. Because newer versions frequently offer better hardware support and can resolve any problems relating to the occurrence of random computer restarts during Windows shutdown due to incompatible drivers, which may occasionally be out-of-date,
Can Ram Cause PC Restarts?
Generally speaking, when a PC operates under a constant load for an extended period of time, it may become overheated. RAM damage brought on by overheating can result in unpredictable PC restarts.
Insufficient RAM or a problematic one-piece that interferes with your system’s operations may be the root of this problem.
By investigating RAMs, I was able to resolve this problem on one of my builds. I started by removing each RAM stick. I then reinstalled each one individually before testing to see which one was defective. My two RAM sticks were all bad, so I tried a different one, and the PC immediately started to function properly.
Pc restart randomly due to multiple reasons can cause a permeant damage to your computer But, if you know what causes the issue and how it can be resolved, you won’t face any problems with your PC in the future.
In addition, make sure you are using the latest version of BIOS, drivers, and other software. Doing so can make your system more stable and reliable too for the long run without facing any issues.
For example, the computer restarts randomly during the shutdown process in Windows due to incompatible drivers, which might be outdated at times.
Ensure that all your hardware is compatible with your build. You’ll have to troubleshoot everything if the problem still precedes. I hope this guide will stop PC reboots randomly.
