It can be quite annoying if your computer keeps shutting down automatically without your permission, or without giving you any warning. You might lose some important and unsaved data in this process. If it is a system crash and not a simple shutdown, then you might also lose the saved data in your hard disk. Frequent random shutdowns may damage the motherboard permanently. So try troubleshooting the problem as soon as possible.
Sudden turning off of computers may be due to many reasons. There are a number of factors that could cause such issues. Damage of windows registry settings is one of the major reasons for sudden shutdown of your computers.
You might want to explore some basic troubleshooting methods to get rid of this problem. In order to choose the correct alternative, you will first need to understand the main reasons for automatic shutdown of systems.
Factors to be considered to avoid random shutting down of computers:
This problem might have started due to something that you added recently in your computer. It may be due to recently installed software or a hardware component. So, consider rechecking all the factors for their appropriate configurations.
There are many types of malware or virus programs that may cause your computer to shutdown suddenly. You will need to get rid of such programs as soon as possible. Run a full system virus scan on all the partitions of your hard drive. Make sure that you update you antivirus program before scanning.
Upgrading and adding of devices should be ideally done one at a time, in order to avoid conflicts between them. Sometimes the system could slow down if the memory is full, and it could also cause sudden shutdown issues. Make sure that you have appropriate RAM according to the size of your hard drive and the type of processor you use. Mismatch in system configurations can cause system shutdown issues.
Resolving heat issues by placing a desk-fan near your personal computer:
Excessive heat may be another cause for CPU failure resulting in random shutdowns. Keep checking the proper functioning of your internal fan regularly. Keep it clean and free from fluff and dust. If the internal fan does not keep your CPU cool, then you can use a table fan for cooling your system. Use a flat fan for cooling your laptops or notebooks. While using a table fan, you could open one of the sides by removing the panel. However, it will make your system vulnerable to dust. It is always a better option to change the internal fan, or to buy a cabinet with double fans.
Checking for issues on safe mode:
Safe mode option in Windows operating system loads all the default programs without loading any externally installed software on your computer. This can test whether the problem is due to any software, or if there are any hardware related issues. Reboot your computer and press F8 button to run your system in the safe mode. If the problem persists, then there is some hardware causing it. You might have to contact a technician to detect the faulty component.
