How to Handle when PC Shut Down Suddenly

One of the most annoying conditions when using a PC comes up when your device suddenly dies and you do not know the cause. Disaster arises when such a thing happens, especially if you have not saved the work that is being done. The more miserable is life. Basically, there are many factors that can explain the sudden death of the PC. But that does not mean that the PC is totally dead, but we are more referring to the condition where the PC suddenly died without we pressing the shut-down button.

Here we want to explain how to find the main cause of sudden PC death. There are several cases of PC death that can be read from several sources on the internet. Here we want to take one example where there is a PC user who just installed the latest motherboard and processor. Instead of enjoying his new stuff, the PC he used instead died suddenly without the owner pressing the shut-down button.

This happens when it runs some heavy apps and games. Meanwhile, the PC is fine when not in use, or is in idle condition. The death of his PC came without warning. No error messages appear or blue screen of death on display. His PC suddenly shut down by itself.

Such problems usually occur when the CPU temperature is too hot. But in the case of the owner above, the CPU and casing temperatures look normal. So the problem is not related to CPU temperature. So what?

The answer is easy: the problem that arises as above is more due to power supply error, in the sense that the PSU is not working properly. If you have similar problems, try monitoring the processor’s clock speed using utilities like TMonitor designed by CPUID. When using the utility, you may find facts where the PC has shut down suddenly when the clock speed of the CPU speed reaches a certain number.

Enable TMonitor, and at the same time run a processor-friendly app (in the sense of not overloading the processor) to check whether the clock processor increase directly affects crashes (sudden death). Check carefully the increase in processor clock speed, and see what number the processor can run normally before experiencing crashes.

In addition, you can also use some kind of software to monitor the amount of voltage provided by the power supply. Such software is usually given directly by the motherboard manufacturer you hold. If not, then you can use other software such as HWMonitor which is also dedicated by CPUID.

Under normal conditions, the power supply unit should deliver 3.3-, 5-, and 12V currents onto the motherboard. However, the delivery current may vary in number if the power supply unit is too low or in defective condition. A power supply that does not work properly should give a sudden shutdown problem when the CPU clock speed reaches a certain number. And if the power supply is not running properly, then the only option is to replace it with a new unit.

While waiting for the arrival of a new power supply unit, you should start limiting the CPU clock speed. This needs to be done to prevent the emergence of an advanced crash that will even cause damage to other components.

To limit the CPU clock speed, connect the Power Options menu inside the Windows control panel 10. Then click on the ‘Change plan settings’ section to enter the advanced menu which is useful in regulating the power used. Alternatively, you can find ‘Change Plan Settings’ by typing “power options” in the search field. The result will look like this:

After entering menu ‘change plan settings’, click on ‘Change advanced power settings’, then sort to the bottom until you find ‘Processor power management’. In this section do click on ‘Maximum processor state’ and lower the setting number to below 100 percent.

About how low the number can be lowered, you can refer to the value of the clock speed of the processor displayed by the TMonitor utility. In other words, set the clock speed of the processor on a secure number that does not cause crashes.

Save the temporary settings, and do not forget to restore them to default settings after a new power supply is installed.
