Why does my computer shut down on its own lately? The experts are here to help!

When the weather is hot in summer, when the temperature of the CPU or graphics card is overheated, it will affect the running speed of the system, so check whether the cooling fan of the CPU and graphics card is running normally or the heat sink has too much dust affecting the heat dissipation ability, and there is a possibility that the system may be infected with viruses and Trojan horses.

This problem has been encountered by many friends. As long as the fan is not installed firmly or tightened, it will cause poor heat dissipation with the CPU and automatically shut down. Your problem should also be here, you carefully disassemble the case to see if your CPU fan is not installed.

It is recommended that you change to a better CPU fan (remember, after installation, there is a manual fan to determine whether it is stable), and it may be caused by computer poisoning.

The automatic shutdown of the computer is mainly caused by the following reasons:

1.Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

3.Power issues. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

4.Software factors. Computer shutdowns caused by viruses or Trojans also abound, especially the recently popular Trojan horses such as robot dogs, which will cause the system to reboot and shut down after being hit by the virus. If you are using Windows

2000 or Windows

XP system, it is recommended that you use antivirus software to patch the blaster in time, and the general problem can be solved.

The computer restarts automatically.

1. It may be a setting problem, solution:

My computer - Properties - Advanced - Startup and Failback - canceled auto-restart.

2. Determine if there is a virus.

3. Check whether the voltage of the power supply is normal.

4. Is the CPU fan not rotating or slow?

5. The software is set in your system and the time is set to shut down.

6. Software conflict, no need to remind, restart. (Not a serious conflict.) ）

7. Check whether the gold finger of the memory is loose, if it is loose, please plug it in.

8. If the machine is running well, disassemble the chassis and clean up the dust inside.

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, and add new heat dissipation silicone grease. If it is not a problem, it may be caused by problems with motherboard parts or power supply, voltage instability, hard disk failure, etc., and the new hardware is not compatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the control panel Turn on hardware and sound Power Options Select Turn off the monitor (select Never or Set Time) Select Never or select the appropriate time from the drop-down list next to Make the computer go to sleep (Win7).

The scheduled shutdown is set, and the system program is wrong.
