Why does the computer keep booting in a loop?

Reasons and solutions for the computer’s continuous startup cycle: 1. Caused by viruses and Trojans, which need to be removed; 2. System files are damaged. System files are damaged, and the system needs to be reinstalled; 3. Hardware reasons , if you have the ability, repair it yourself. If you don’t understand, you can send it to the repair center for repair.

The reasons and solutions for the computer’s continuous startup cycle

1. Software reasons

1. Virus "Shock Wave" When the virus attacks, it will also prompt that the system will automatically start in a few seconds. Trojan horse programs remotely control all activities on your computer, including causing your computer to restart.

2. System files are damaged. System files are damaged, such as KERNEL32.DLL under Win2K, fonts under the Win98 FONTS directory and other basic files when the system is running. The system will not be able to complete initialization when it starts. Forced restart.

3. Timing software or scheduled task software works

Solution:

1. Remove viruses, Trojans, or reinstall the system.

2. If you set the time to restart or load certain work programs in the "Scheduled Task Bar", when the scheduled time comes, the computer will also start again. In this case, we can open the "Startup" item, check if there are any executable files or other scheduled work programs that we are not familiar with, block them, and then turn on the computer to check. Of course, we can also directly enter the "Msconfig" command in "Run" to select startup items.

2. Hardware reasons

The chassis power supply is insufficient, the DC output is impure, and the dynamic response is slow. Users or installers often do not pay attention to the power supply and use cheap power supplies. Therefore, this is one of the biggest suspects of causing the system to automatically restart.

(1) The output power of the power supply is insufficient. When running large-scale 3D games and other software that occupy a large amount of CPU resources, and the CPU requires high power supply, the power supply power is insufficient and overloaded, causing power protection and stopping the output. After the power supply stops output, the load is reduced, and the power supply starts again. Since the protection/recovery time is very short, the performance given to us is that the host automatically restarts.

(2) The DC output of the power supply is impure, and digital circuits require pure DC power supply. When the harmonic content in the DC output of the power supply is too large, it will cause the digital circuit to work incorrectly, manifested by frequent crashes or restarts. .

(3) The workload of the CPU is dynamic, the current requirements are also dynamic, and the dynamic response speed is required to be fast. Some poor-quality power supplies have long dynamic response times, which can also cause frequent crashes or restarts.

(4) After updating equipment (high-end graphics card/large hard disk/video card) and adding equipment (recorder/hard disk), if the power exceeds the rated output power of the original power supply, it will cause frequent crashes or restarts.

Solution:

1. Replace the high-quality high-power computer power supply now.

2. When the memory chip is slightly damaged, the system can pass the self-check when it is turned on, or it can enter the system. When running some software with high throughput, it will restart or crash. Solution: Replace the memory.

3. Setting the CAS value of the memory too small will also cause memory instability and cause the system to automatically restart. It is generally best to use the default settings of the BIOS and do not change them yourself.

4. Disable the second-level cache (L2) or first-level cache (L1) in CMOS, or replace the CPU to exclude it.

5. Add a voltage regulator (not UPS) or a 130-260V wide switching power supply.

Generally speaking, if it is caused by software problems, you can try to use conventional methods such as anti-virus and Trojan removal to repair it. If the infinite restart is caused by a hardware problem, it is recommended to repair it yourself if you are able. If you don't understand, you can send it to a repair center. This kind of problem is not uncommon, and I believe many maintenance centers will repair this fault.
