Why does my computer keep crashing?

It can be very frustrating to use a computer that crashes, especially if you can not understand why and how it can be fixed. Random crashes can result in data loss, changes in files and a computer breakdown if they are not addressed. Crash is categorized as a random reboot or shutdown, freeze, blue death screen, or unwarnably turn off your screen. Here are some common causes of computer crashes and how to fix them: heat The most common cause of random crash is an overheating computer. If your PC or laptop doesn’t have enough airflow, the hardware is too hot and it won’t work properly, which will lead to a crash. Each computer is sold with an installed fan to counter the heat generated by the machine.

However, they are likely to become obstructed by dust, food crumbs or pet hair which can lead to a failure of the fan and it is therefore important that the fan is cleaned regularly to prevent this. Similarly, don’t have large items that block air ventilation, as this can lead to a failure of the fan and a crash of your computer.

Another helpful tip is to listen to the fan of your computer. The more you use your PC, the more heat the processor and the hard drive generate. This means that the fan will have to work twice as hard to cool down the machine and make more noise. Your fan is meant to handle this heat level and operate quietly, but eventual failure is caused by this type of intensive use. So if you can hear your fan audibly, allow your computer to refresh before you use it again.


If you are experiencing random freezes or shutdowns, the hardware of your computer could be defective. Consequently, it is important to ensure that this is not due to the registry of operating systems. The registry is an archive to collect and save the Windows component, hardware, software, and application configuration settings. A registry can get corrupted but can be fixed by cleaning the registry software to restore the system.

Your computer could also crash if you have a driver fault. This may be due to corruption of files or bad sectors on your hard disk. Usually you receive warning signs from Windows that this type of crash comes with system messages or disk access slowdowns.

Identifying which driver causes the fault is very difficult, so reinstalling common drivers such as Graphics and the Motherboard is the most sensitive solution. Use driver installation software to ensure that it is up-to-date and properly installed to speed up this.


Although most crashes are caused by malware, it is rarely the case. Software rarely crashes your computer altogether. If a program you are using inadvertent crashes or freezes, your operating system often gives you the option of shutting off the program rather than letting the entire PC get affected.

Sometimes software contains bugs that freeze your computer, if that happens be patient and wait until your computer shuts down the software or restarts you your computer manually.

Naturally, there are many forms of malware and viruses which can crash your computer. Here are some tips for checking whether you think your computer can be infected and also some information on malware prevention.

You can also use the built-in’ reliability monitor’ for your computer crashes if you use Windows Vista or a more recent OS.

Simply press the windows key and search’ reliability’ or access the monitor from your control panel to view a history of crashes of your system. We hope this will help, and if your computer doesn’t crash, but slow down or fail, we’ve also written about this: Top Tips for your computer.
