Introduction
An operating system is a software program that manages and operates computing devices such as smartphones, tablets, computers, supercomputers, web servers, automobiles, network towers, smartwatches, and so on. It is the operating system that removes the requirement to understand coding languages in order to communicate with computing devices. It is a graphical user interface (GUI) layer that serves as a bridge between the user and the computer hardware. But, have you ever imagined how tough it would be to handle things if the operating system stopped working? That's scary enough, right? Unfortunately, it is possible that the operating system will encounter certain failure difficulties, causing it to stop working.
In this article, we will be learning about operating system failure and its causes. How to recognize failure and get over it.
System Failure
A system failure is defined as a breakdown of any system hardware, operating system, or application software that prevents the system from performing its intended function.
When a computer or other system is built, it is designed in such a way that each component of the system is dependent on the others. When one component fails, it can cause other components to fail as well.

Operating System Failure
An operating system failure can be caused by a hardware malfunction or a software crash, and it usually results in the inability of the operating system to boot. The OS may repeatedly reboot and freeze with an error message displayed on the screen, or it may completely stop running with no notifications.
On Windows PCs, an error message is frequently displayed as a Blue Screen of Death error as shown below:
Despite the ever-increasing dependability of modern-day running structures, operating systems are not designed to absolute perfection. Most of them will be affected by technical issues sooner or later.
Cause Of Failures
The causes of operating system failure are as follows:
- Software Problems
- Hardware Problems
Let us discuss each of them one by one:
Software Problems
System failures can occur as a result of software problems if the issue within the software, such as a wrong line of code, is severe enough.
If all of the computing device's hardware is working properly, the failure was most likely caused by a software glitch, such as malware infection, faulty device shutdown, package conflicts, incorrect system update, horrifying drivers, incorrect settings, or a boot sequence that corrupted the partition table, master boot record, critical system documents, or even the entire report system.
Few software problems are as follows:
- Improper Drivers
To use additional hardware, we'll need drivers, which can usually be downloaded from the internet. These drivers may be tainted with bugs. These flaws can cause the operating system to crash.
The "Safe Mode Boot" option is available in most modern operating systems. Safe Mode Boot is used for driver troubleshooting and locating. In Safe Mode Boot, only the most critical drivers are loaded, not all of them.
- Thrashing
When two programs compete for control of the same resource, a deadlock occurs. During a deadlock, the operating system may attempt to switch back and forth between the two programs. It eventually leads to Thrashing, in which the hard disk is overworked by shifting information between system memory and virtual memory incessantly, resulting in a system crash.
- Virus
You probably have heard of viruses from your childhood days. A virus is a small piece of software code that is embedded in the operating system. A virus on the system may replicate itself. Viruses are especially dangerous because they can modify and delete user files as well as cause machines to crash. As the user interacts with the programs, the virus becomes embedded in other files and programs, potentially rendering the system unusable.
- Corrupt Registry
The registry is a small database that contains information about the kernel, drivers, and programs. Before starting any app, the operating system searches its registry. Registry corruption can occur as a result of incorrect application removal, careless registry changes, or having too many installed applications.
Even minor Registry damage can set off a chain reaction within your operating system, destroying your data beyond repair.
For example:
A faulty registry in Windows 10 can cause the following problems on your system:
You will be unable to boot your computer. During startup, you may receive a blue screen error, and the boot will remain restricted to the blue screen.
You will be able to boot the system because the damage is minor, but you may experience a blue screen error while operating your computer. Your unsaved data will be erased. Although you will be able to access your PC for a short period of time if this type of error occurs, the chances of further damaging your PC's Registry could be increased.
- Compatibility Error
This type of problem frequently occurs when old apps in Windows no longer work as a result of an upgrade. When you encounter this problem, you are aware that it is one of the symptoms of an operating system breakdown, but you can easily resolve it. In most cases, Windows includes an in-built capability for making applications compatible with the new version.
- Trojan Horse
A Trojan horse, also known as a Trojan, is a type of malicious code or software that appears to be legitimate but has the ability to take control of your computer. A Trojan is a malicious program that is designed to harm, disrupt, steal, or otherwise harm your data or network.
To deceive you, a Trojan masquerades as a legitimate application or file. It attempts to trick you into installing and running malware on your device. Once installed, a Trojan can carry out the function for which it was designed.
A Trojan is also known as a Trojan virus or a Trojan horse virus, but these terms are interchangeable. Viruses have the ability to execute and replicate themselves. A Trojan, however, cannot. Trojans must be executed by the user.
Hardware Problems
System failures can also occur as a result of a hard drive with crappy sectors, which prevents the operating system from reading data from the hard drive. Hardware-related issues frequently result in OS errors because the PC becomes unable to function normally.
For example: A faulty power supply causes a system to shut down immediately; a bad processor makes it impossible for the computer to function in general, and an incorrect RAM chip may also prevent the OS from accessing critical statistics and many more.
Few hardware problems are as follows:-
- Overheating
Excessive heat damages the sensitive components inside your computer. A system that is overheated for an extended period of time may be permanently damaged.
Moreover, Overheating is a significant hardware issue that causes operating system failure. A fan is built into the CPU of a computer to keep it cool. The fan may become worn and inefficient over time, or it may simply be incapable of performing the functions of your computer.
- Motherboard Failure
A failed motherboard may result in a system failure because the computer is unable to respond to system requests or function in general.
The computer may begin to boot but then stop. Increased Windows errors, also known as "blue screens of death," are signs of a failing motherboard. The computer may freeze for no apparent reason, or previously connected devices may cease to function.
- Power Problem
Incorrect operation of the System Power Supply may result in the system being shut down immediately.
Power supply issues typically manifest themselves under load, so if your computer crashes when it requires more power, there's a good chance that your power supply is to blame.
- Bad Processor
A faulty processor can and often does result in a system failure because the system may not function properly if the CPU is not functioning properly.
Now the biggest question which comes to mind is how to recognize the symptoms of operating system failure. Let’s discuss them as well:
Recognize Symptoms Of OS Failure
There can be many ways through which we can find the symptoms of OS failure:
- Failure to Boot
If you are unable to boot, the operating system may have been damaged. The system's boot order has been altered. You can investigate the booting process and sequence configuration. In the event of an operating system failure, you must reinstall Windows. Please keep in mind that the issue could be serious. It is one of the most accurate predictors of operating system failure.
- Slow System Performance
The system's performance has deteriorated significantly. It is the ideal sign if you are looking for how to recognize signs of operating system failure on the internet. In this case, you can check to see if you have the most recent versions of Windows installed on the system. Security patches, too, must be kept up to date. The system will then resume normal operation.
- Missing DLL Information
This message appears if the dynamic link libraries on this computer are missing. This could be due to the use of third-party applications, which causes a lot of redundancy in all of the applications. There are numerous versions of these libraries. If you have not updated, you may receive a popup message.
Overwriting previous versions with new versions is a risky situation. The reason for this is that it may cause a malfunction. This is one of the most obvious signs of an operating system failure.
- Computer Refuses To Start
There are times when the computer simply does not start. The operating system has become corrupt. Typically, the result is a complete computer crash. The other reasons could be hardware-related. As a result, you can seek the assistance of a computer repair expert to resolve the issue.
