A computer that just goes off without any error messages or warnings can be pretty frustrating. There are a few reasons that a computer is turning off by itself with no warning. A few of the most common reasons are overheating, a hardware issue, or even malware. Let’s look at how we can identify and fix these issues.
When a computer turns off by itself, one really common reason is overheating. If this is the case, then the only way to correct it is by first finding out what causes the overheating. In most cases, it’s the accumulation of dust and dirt over time inside the computer that leads to a degradation of the internal cooling system. As such, the next step at correcting the problem would be by clearing out the dust. Please note that your computer does not necessarily have to be hot for it to shut down unexpectedly. Manufacturers place several safety parameters when designing computers, and one of them is the coordination of the power system with the cooling system. So, if for any reason, such as the presence of dirt particles, the fan cannot run or runs slowly, the power supply may still shut off.
