What is the reason why the computer automatically shuts down after it is turned on?
Generally speaking, shutdown is caused by hardware, and automatic shutdown is a program of computer self-protection. To avoid serious damage to the machine, please try to eliminate:
1, viruses and trojans are stationed, which leads to the startup and shutdown. Remove viruses and Trojans.
2. Reset switch on the front panel of the chassis. Replace the reset switch.
3. Insufficient chassis power supply, impure DC output and slow dynamic response. There is a power supply for changing electricity.
4. The power supply voltage is unstable. Add regulated power supply or use 130-260V wide switching power supply.
5. Poor memory contact, poor thermal stability, chip damage or wrong setting. Wipe the golden finger with an eraser, clean the slot, and then insert it tightly to replace the defective memory.
6. External cards such as graphics cards and network cards are not standard in workmanship or poor in quality or poor in contact. Clean the golden finger with an eraser and insert it tightly.
7. If the heat dissipation is not good, check the CPU and video card fan, dust and oil the fan and replace it with a new one.
8. The primary and secondary caches inside the 8.CPU are damaged. Shield the second-level cache (L2) or the first-level cache (L 1) in CMOS, or replace the CPU.
9. If the system file is damaged, please use the system CD to repair the system.
What should I do if the computer shuts down automatically after starting?
1, open the "control panel" first, and input it directly into the control panel during operation, or open it anywhere in my computer.
2. Select View Mode as the category, find System and Security, and then click Enter.
3. Find the system options, and then click Enter.
4. Select Advanced Settings on the left. In the pop-up property box, select Advanced, and then select System and Fault Recovery.
enter
5. Enter Settings, select System Fault, and check whether system restart is checked. If not, please check it, click OK, and then restart to see the effect.
The above is the analysis of the causes of automatic shutdown after computer startup and the introduction of related solutions. In Bian Xiao's view, if there is nothing wrong with the hardware, the virus or Trojan horse is the most important reason. When downloading software or movies, you must go to a regular mall or use a safe player to download them. You must keep the habit of cleaning up viruses every day to avoid computer attacks by viruses.
