The reasons for a computer repeatedly powering off shortly after startup and restarting are:
- A computer system program errors or crashes, requiring system restoration or reinstallation.
- Power supply issues, with voltage levels too low.
- Insufficient computer memory and excessive programs running.
- CPU temperature protection settings triggering due to excessively low warning temperatures.
- Computer infected with malware or trojan programs.
01
Computer System Program Error or Crash
Firstly, the first factor is a computer system issue. The computer powers off within a few seconds of booting up, repeatedly restarting. Sometimes, it’s similar to a computer blue screen or the appearance of garbled characters. It’s a problem with the computer system, such as a system crash or system disorder. When a simple power cycle doesn’t work, it’s time to consider restoring the system or reinstalling it. Of course, the prerequisite is to back up important files on the computer to prevent data loss after reinstalling the system.
02
Power Supply Issues, Low Voltage Supply
The second factor is caused by power supply problems in the computer. Some power supplies, although they claim to reach a certain wattage, may not deliver the actual power required. This can lead to significant fluctuations in the output current of the power supply, failing to meet the current conditions necessary for the stable operation of the system, resulting in the system self-restarting.
Simultaneously, when the hard drive operates at a lower voltage, it can lead to errors in the file allocation table or reports of bad sectors, causing the system to frequently freeze or restart.
03
Insufficient Computer Memory, too many Computer Programs
The third factor is related to computer memory. Many users have been using their computers for a long time without considering replacements. Some computers still have only 2GB of RAM. However, in today’s information age, computer programs and software are constantly evolving. Computers with limited memory struggle to handle modern programs and software. As a result, when multiple programs are downloaded, computers with inadequate memory may experience crashes and freezes, often leading to frequent restarts as a way to free up memory.
The solution is to uninstall unnecessary software to reduce the computer’s workload or to add more RAM to expand the computer’s available memory.
04
CPU Temperature Protection Settings, Low-Temperature Warning
As we all know, our computers have built-in overheating protection features. When the CPU temperature reaches a certain peak, the computer will automatically shut down to prevent overheating. If your computer powers off within a few seconds of booting up, it’s likely due to an issue with the CPU temperature protection settings. For instance, the CPU’s low-temperature warning setting might be too sensitive, causing the computer to shut down due to overheating shortly after startup.
The solution is to adjust the protection temperature settings in the BIOS to a more suitable level. Additionally, it’s important to improve system cooling by regularly cleaning dust from inside the computer and applying thermal paste.
05
Computer Infected with Trojan Program
The final factor is the presence of a Trojan program on the computer. Never underestimate the impact of a Trojan program. Symptoms such as computer blue screens, garbled errors, frequent restarts, black screens, or severe system slowdowns should all raise concerns about the possibility of a Trojan program. The purpose of a Trojan program is to take control of a user’s computer to steal information, which can result in the computer becoming unresponsive or even preventing it from booting up properly.
The solution is to use security software to scan for and remove the Trojan program. If you cannot access the software or the computer fails to boot up properly, the last resort may be to restore or reinstall the operating system.
