What is the reason for the sudden restart of the computer on its own??? As the title suggests, thank

Hello friends, the computer will automatically restart as soon as it is turned on There are six reasons:

The first reason is: the general computer will automatically restart as soon as it is turned on, 60% of the host power supply is a problem, when the filter capacitor of the power supply is bulging and leaking, resulting in insufficient power supply, it will form an automatic restart of the computer, processing methods, and replace the power supply.

The second reason is that there is a problem with the CPU fan on your computer, or the clip of the heatsink is loose. When the CPU fan is stuck or broken, causing the CPU to not cool down, when the temperature reaches the set temperature of the motherboard, the motherboard starts the self-protection function, and it will automatically turn off the power supply, and then restart, so you just need to change the fan, or because the ash blocks the fan, and get the fan through.

When the card of the radiator is loose, as soon as you turn it on, the CPU detects that there is no heat sink to cool down, and immediately stops working and cuts off the power supply, so it will automatically shut down and restart after a few seconds, and restart repeatedly, as long as the card is reinstalled, you can add some silicone grease to the CPU. This is all to cool down the CPU, only the CPU can ensure the normal use temperature will not automatically restart repeatedly.

The third reason is: the graphics card's video memory integration block is soldered, resulting in poor contact with the motherboard after powering up, it will automatically restart, and the solution is: it can be solved by soldering the video memory, or change the graphics card.

The fourth reason is: Your voltage is unstable, that is, lower than 170V, higher than 240V, can not reach the starting voltage and exceed the specified voltage, will make the computer restart Jianyi buy a UPS, also called uninterruptible power supply, so that it can not only stabilize the voltage, but also have 30 minutes of time to save data, the fifth reason is: the computer poisoning destroys the boot area and the system, and the boot area cannot be found when the boot is turned on, so it will naturally restart repeatedly, and the solution is to repair the boot area and reinstall the system. (Or a one-click restore will do). Another thing you need to do is to restore the BIOS to its factory value.

You can also discharge the BIOS (that is, open the case, remove the motherboard battery, wait for 10 seconds and then press back to the motherboard, install the machine), these are done to eliminate your problem.

The sixth reason is: the computer's boot button or restart button is stuck, and it can't bounce up, resulting in the machine has been in the state of pressing the button, and it will naturally start automatically after booting, or restart repeatedly.

But your problem is likely to be the first and third or sixth, and the third type has the highest percentage.
