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.

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.

Final Thoughts

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.
