There are a lot of reasons your computer can crash without warning, some of them are hardware related, while others are software related. The most common cause of computer crashes is heat.

The computer is equipped with fans to ventilate and cool the innermost part of the system, these fans help to prevent overheating, but there are a number of factors that can cause fan failure which will ultimately lead to your computer overheating and crashing.

Follow us as we discuss how heat can cause your computer to crash, how to prevent overheating and fan failure, and also other things that can lead to the freezing up or crashing of your computer.

 

What are the causes of random computer crashes?

Overheating: this is one of the common reasons your computer can freeze up. The computer is built to take on a lot of work, but when the workload is greater than the capacity of the CPU, the computer will start heating up; the greater the workload, the more the heat. But this is not a problem because the fans installed under your PC will cool the CPU and ensure that your computer does not crash.

However, the computer fan can fail if there is dust, debris, and dirt accumulation in the air vent. Debris and dust particles can hamper the work of the fan, this means the fan won’t be able to blow enough air to cool the heating computer. Proper maintenance and cleaning of the air vents will prevent an accumulation of dust and debris in the computer.

Another cause of overheating is blocked air vents. Whenever you are using your computer, make sure to place it on a flat and hard surface. Putting it on your bed, sofa, or lap will block the air vents and prevent the fan from effectively cooling the heating CPU. Use laptop desks or flat tables when using your PC.

Hardware failure: this is the second most common cause of computer crashing. When a computer screen freezes or the Blue Screen of Death (BSOD) pops up, most people think it is as a result of software failure. The truth is that when a software program crashes, Windows terminates the program and keeps the system running.

Hardware failure, on the other hand, will freeze up the computer screen and shutdown the system.

A corrupt operating system registry is one of the common hardware related causes of random computer crashes. The operating system registry is where the configuration settings of the computer’s hardware and software are located. If these settings ever get compromised, it can lead to the crashing of your computer. You can clean a corrupt registry by using a registry cleaner software.

Another cause of hardware failure is driver problems. Bad sectors in your hard drive; insufficient RAM space, and misconfigured hardware settings can contribute to sudden system freeze and shutdown. This is why it is important that you update your system drivers regularly and also make sure that any hardware installed is fully compatible with your computer. Additionally, a RAM upgrade will resolve any problem arising from insufficient RAM space.

Malware: malware is a malicious virus that invades your computer and aims to take control of it. You can get malware on your computer by visiting websites that do not have proper security, downloading from the internet, advertisement notifications, email, and so on.

A malware attack would usually not kill your computer, since the virus would also prefer a working Windows.

In order to prevent system crashes from malware, you need to update your windows defender to make it capable of detecting and terminating these viruses before they can pose a problem to your computer. You can also terminate them yourself by scanning your computer with antivirus software. The antivirus will provide you with a security update and advise you on potential security risks or loopholes in your system, addressing these risks will make your system more secure.

Software issues: while it is not common, a problem with your software can make your computer crash.

Usually software problems will not make your computer screen go blank or freeze up, in fact, when a computer program goes bad, Windows normally recommends that you close the program and stop the issue from affecting the rest of the computer. But a software problem can get bad enough to cause a system crash.

Bugs are the chief cause of software related crashes. When your system software has a bug, it can cause glitches in the computer screen, especially when a program is running, or even cause the screen to completely freeze up. In the extreme, these bugs can cause the system to unilaterally power down.

Updating your operating system on a regular basis will help prevent bugs in your computer. These system updates contain the latest security configurations which will help keep bugs out of your computer.

Power surges: these can also cause your computer to crash. Having too much current fed into your system can make the computer power down to protect itself. This is why it is advisable that you use a power breaker or stabilizer whenever you have your computer plugged in.

 

Conclusion/Summary

So far, we have discussed the numerous factors and problems that can make your computer crash. It is important to know that the 5 causes discussed above are not the limit. There are more reasons why a computer crashes. However, note that when a computer shuts down by itself, it is usually to protect itself from more damage. Overheating can lead to the melting of some cords or wires in the inner layer of your computer. It can also cause CPU failure if it rises unchecked. Other causes such as hardware failure, malware, viruses in the software, outdated drivers, etc, can also cause the total breakdown of your computer if not promptly addressed. So when the computer shuts down by itself, it is an emergency measure designed to give you time to find a solution to the problem.
