Causes and Fixes for Automatic Computer Power On/Off
1. High Computer Temperature
Most hardware components in a computer have a maximum temperature threshold. Exceeding this threshold can damage the components. Therefore, computer components are programmed to automatically shut down when they reach this temperature limit. For example, the CPU temperature threshold is usually around 75°C.
To begin, download temperature monitoring software such as CPUID HWMonitor.
After downloading and installing the software, you will see the following interface:
As observed in the image, line 1 displays the motherboard's temperature, currently at 66°C. Line 2 indicates the CPU temperature. Consider monitoring the CPU temperature after running for a while. If it rises excessively, seek assistance from computer store personnel to apply thermal paste for the CPU.
You should check if your power supply unit has the capacity to support your components. If the PSU is too weak and your computer has a dedicated graphics card - the component consuming the most power - consider upgrading to a stronger PSU.
Here are three common causes leading to the issue of a computer restarting immediately after shutdown for your reference. If your computer experiences any of these three conditions, follow the instructions provided. Otherwise, take your computer to the nearest computer repair shop for timely intervention before the situation worsens.
