You were engrossed in the highlights of a movie and then the computer shut down, now leaving you with nothing but a blue reboot screen - an annoying experience. Perhaps you've noticed that computers are randomly restarting more frequently these days, and the problem has become too much to ignore.
What causes a pc to randomly restart? In this article, we summarize a few possible reasons and offer some solutions to the problem.
You may be wondering about sudden reboot - "Why does my pc randomly restart?", here are some summarized possible reasons.
Reasons for PC randomly restart include outdated drivers, hardware failure, CPU overheating, system errors and power supply problems. Apart from these, software conflict is also one of the common causes, which is usually caused by software updates, installation of new software or Windows OS updates.
Another potentially influential factor is malicious program infections such as viruses, spyware or adware, which can cause serious damage to the system and lead to abnormalities that cause the computer to reboot randomly.
In addition, improperly assembled hardware (such as memory sticks, graphics cards, motherboards, etc.) or incompatibility between hardware can easily affect the stability of the system, so it is also one of the possible causes of random computer reboots.
You can no longer tolerate the bomb of uncertainty when your computer randomly restarts again without any warning message, it has repeatedly interrupted your ongoing work or recreational activities. We understand your anxiety and have provided the following solution to get started now.
The Windows Auto-Restart feature automatically restarts your system when it encounters a serious error without displaying any error messages. Although disabling this feature won't solve the problem completely, it will give you a chance to get error messages.
Step 1: In the search box of "Settings" of Windows 11 or 10 PC, type "Advanced system setting" and enter, then click on the target option to open the "System Properties" window.
Step 2: Click the "Settings" button in the "Startup and Recovery" section under the "Advanced" tab.
Step 3: In the "System Failure" section, uncheck the box next to "Automatically Restart" and click the "Ok" button to save and apply the changes.
Drivers are the bridge between hardware accessories and the operating system for effective communication, they are an integral part of ensuring the stability of your computer system. If the graphics card driver is not compatible with the system or other software, there is a high probability that the computer will crash or restart automatically.
Therefore, we recommend that you try reinstalling or updating the drivers to solve the problem of your computer rebooting randomly. You can do that by visiting Device Manager or downloading and installing the latest drivers from the official website.
Option 1: Open "Device Manager", then expand "Display Adapters". Right-click on the card and click on the "Update Drivers" option, and select either Auto Search or Manual Installation.
Option 2: Visit the official website of your graphics card, such as AMD, and select the appropriate driver according to the model and version of your graphics card, open the file after downloading and follow the prompts to install it.
Have you recently installed any new hardware devices? Such as CPU, RAM, video card, etc. If yes, then your computer's random reboot problem may be caused by an old BIOS version that is not compatible with the new hardware. Apart from that, BIOS updates usually contain fixes for known issues and security vulnerabilities, which can have a positive effect on improving the stability of your computer system.
However, a wrong BIOS update can damage your computer's system, and if you mess up, your computer could break as a result. If you don't have the confidence to complete the process correctly, seek professional help.
Finally, if you have changed any configurations on your BIOS, It will be better to reset it to defaults.
When the system is experiencing serious problems or unusual behavior, such as a computer that keeps restarting randomly, a clean install of Windows OS is an effective solution worth considering. It removes software glitches, driver or system configuration error problems that may have originated on the old system.
Note: A clean install will completely erase all data on your hard drive, including files, programs, and settings, so be sure to back up all important files and data before performing a clean install.
iSunshare CloneGois a dedicated backup utility that provides both whole disk backup and partition backup options, which you can use to transfer some important data from C drive to other disks, clone specific partitions to external drives, or clone HDD to SSD.
When the CPU temperature reaches a certain value, it will automatically activate the high temperature protection mechanism to avoid overheating and burning. Once the CPU high temperature protection mechanism is triggered, the system will downclock to indirectly reduce the CPU processing speed. If the temperature rises to the maximum threshold in the CPU high-temperature mechanism, the computer may simply shut down or reboot.
You can monitor the CPU temperature using software such as Core Temp or SpeedFan. If you notice an abnormally high CPU temperature, clean the heat sink and ensure good ventilation.
Random Access Memory(RAM), a type of internal computer memory that is used to run programs. If there is an error in the RAM then the computer may keep crashing and restarting randomly. You can use the built-in memory diagnostic tool in Windows 11 and Windows 10 to check if there is a problem with RAM.
Step 1: Type "mdsched.exe" in the search box and run this command as administrator.
Step 2: Then, a "Windows Menory Diagnostic" window will pop up and it is recommended to select the first option: "Restart Now and check for problems". Don't forget to save your work in progress and files before rebooting.
Step 3: The system will reboot immediately and run the test program automatically, wait patiently for the test to complete, which usually takes 5-30 minutes. The test results will be displayed at the bottom right of the screen after you log in to Windows.
Or you can navigate to "Event Viewer" > "Windows Logs" > "System" > to locate the event log.
Proper and correct power settings are one of the guarantees for stable computer operation. By adjusting the power advanced settings, you can optimize the system's power management, heat dissipation and reduce power stress, thus reducing the problem of random reboots.
Step 1: Type "Power plan" in the search box and click the match option.
Step 2: In "Edit Plan Settings", select and click "Change advanced power settings".
Step 3: Then, there are various power settings in "Advanced Settings". In the "Balance" section, click "Processor power management" to see the minimum processor status, which should be set to 5% or even 0%.
Desktop computers can easily shut down, reboot or even fail to start once they don't have a stable power supply. So if none of the above methods can fix the problem, then you should check if your computer's power supply is working properly.
Common problems include disconnected, loose or detached power supply and insufficient energy from the power supply unit (PSU), all of which should be checked one by one.
It is a common situation that random computer reboot will lead to some data loss. What should you do if you find some important files lost or damaged after your computer is turned on again? Professional data recovery software can retrieve them easily.
iSunshare BitGenius is one of the popular data recovery tools that can easily recover all types of deleted or lost files, including photos, audios, emails or documents. It doesn't require you to have any technical foundation, just a few simple steps to retrieve and get back lost data, no matter they are caused by computer crashes, formatting, or accidental deletion.
Step 1: First of all, download and install BitGenius on your computer from the official website of iSunshare and run the software.
Step 2: Select a scanning location, which can be any partition or external disk (including SD card, USB drive), and then click "Start" to start the file recovery process.
