Software Errors

Ever since the dawn of time (which happens to be the release of Windows XP) Windows has had an in-built algorithm to restart every time whenever a system error occurs. This keeps your system and your data safe and usually isn’t a serious problem. It’s a built-in safety mechanism, after all. However, if the Windows restarts very frequently, this might mean that there a constant error occurring in your system. In this case, we recommend consulting a computer repairs specialist, such as us at Fix My Home Computer.

Hardware Issues

Hardware inside your computer is not immortal and wears out same as the components of any machine. When the hardware starts to malfunction, it generates errors within your computer system and your computer restarts. This could be a sign that some of your computer hardware components are malfunctioning.

Another hardware related-reason could be the drivers of your hardware. Hardware drivers are software protocols that operate and control the hardware components. Perhaps the drivers on your computer should be updated or rolled back to an earlier version instead.

Finally, the reason for constant reboots might be as simple as one of your hardware components not connected or configured properly. Once again, we suggest that you contact a professional computer technician to check the connection of your hardware components.


There’s plenty of computer threats out there, the most common being computer viruses and malware. Some of them are designed to compromise your data, some – to monitor your activity. Some – to make your computer automatically restart as frequently as every 30 seconds. If you notice that your computer is behaving strangely – frequent reboots aside, it might be infected by malware.

Heat Issues

Most computers have an in-build kill-switch that either turns your PC off or restarts it when some of the hardware components get too hot. Usually it’s the most vital parts, such as the CPU, the Graphics Card or the Hard Drive. Those components might be overheating because they are close to failing, or due to problems with your computer’s cooling system. In most cases it’s the cooling system of the PC’s power supply that is malfunctioning. Those issues should be resolved as fast as possible. If neglected, they might lead to permanent, irreversible damage to your computer.
