Why does the computer restart on its own at every turn?

1. The power supply is one of the biggest suspicions that cause the automatic restart of the system Inferior power supply can not provide enough power, when the number of devices in the system increases, the power consumption becomes larger, and the voltage output of the inferior power supply will decrease sharply, which eventually leads to the unstable work of the system and the phenomenon of automatic restart. Excessive voltage fluctuations can also lead to damage to hard drives and other devices. 2. Memory problems will also cause the system to restart The probability of memory errors causing the system is relatively large.

In addition to ruling out poor contact between the memory and the slot, a quality issue with the memory itself should be suspected. In addition, setting the size of the cl value of the memory will also cause the memory to be unstable, causing the system to automatically restart. Simple solution:

If you are using SDRAM, set the CL value to 3, and if you are using a motherboard with a VIA chipset, it is recommended to disable the "memory interleaved execution" function. Lowering f is also a solution, but the system performance will be reduced a lot. 3. Excessive fluctuations in the power grid voltage will also lead to system restart If your computer shares a plug-in board with high-power appliances such as air conditioners and refrigerators, the voltage supplied to the computer will be greatly affected when these appliances start, which is often manifested as a system restart.

The best way is to configure the UPS for the computer to power the computer, (of course, this also depends on the situation) pay attention to other electrical appliances and do not connect to the UPS. 4. Poor contact of the power socket After the power socket is used for a period of time, the elasticity of the reed is slowly lost, resulting in poor contact between the plug and the reed, the resistance is constantly changing, and the current fluctuates, and the system will naturally be very unstable, once the current does not meet the minimum requirements of the system operation. The computer will restart.

Solution: Choose a socket with good quality. 5. The temperature of the system is too high At this time, you should check whether the CPU fan is running normally and whether the heat dissipation conditions are good. Today's motherboards have the function of detecting the CPU and system temperature in the BIOS through a special control chip.

If you find that the temperature is too high, you should replace the fan or add one. There are often netizens in 52 hardware (

Interested readers can take a look at 6Hardware compatibility issues are generally caused by the motherboard's compatibility with memory modules. But I've also come across instances where the graphics card causes the system to keep restarting.

7. Set up the remote wake-up function in the BIOS (this is generally the reason for the cat, if you use broadband Internet access and you also have an inner cat installed in the machine, it is best to remove the inner cat.) Of course, it's a good idea to check your hardware before you check for viruses, because a virus will also cause an automatic restart. (Upgrade the virus database to kill viruses in safe mode).

Summary. 1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

Fellow, I really didn't understand, I can be more specific.

2. The CPU or other hardware temperature is too high, and the memory and display card are incompatible or faulty. 3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to re-divide the spring area and reinstall the system. 4. Change the default automatic restart of the system

Right-click on My Computer Properties Advanced Settings in Startup and Failback Remove the checkmark before "Auto Restart" in System Failure, and then press OK and Apply to restart your PC.

There are a number of reasons why your computer automatically restarts, and here are some of the common possible causes:

Software or system failure: A software program or operating system on your computer may have a malfunction or conflict that causes it to restart automatically. This can be due to faulty drivers, virus infections, operating system errors, etc.

Solution: Make sure your operating system and software programs are up to date, and do a full scan of your system and antivirus software. If the problem persists, try reinstalling or updating the problematic software program, or consider restoring the operating system to its original state.

Hardware issues: Some hardware components may be faulty or not working properly, such as power issues**, memory failures, overheating, and more, which can cause your PC to restart automatically.

Solution: Check whether the connection of the computer's hardware is stable, and make sure that the memory modules and other hardware components are installed correctly. Clean the inside of your computer from dust and ensure good heat dissipation.

If the problem persists, further hardware troubleshooting or replacement of the problematic hardware component may be required.

High temperature overheating: If the temperature of your computer is too high, it may cause it to restart automatically to protect your computer from damage.

Solution: Make sure the computer is well ventilated, clean up and clean the inside and outside of the computer. You can try using cooling pads, adding fans, or improving air flow to lower the temperature.

If your PC still overheats and restarts automatically, you may need to check hardware components such as the cooling system, fans, or processor coolers.

The automatic restart of the computer may be due to a problem with the software and hardware, it is recommended to check and update the driver or contact a professional to fix it.

If you think it's the CPU temperature that's too high, it's better to deal with it like this:

1.First of all, turn it off, remove the CPU heatsink, remove the fan on the heatsink, clean up the dust, dial the fan blades to see if it rotates smoothly, if it is difficult to rotate, uncover the label on the back of the fan to see the bearing, add a small amount of lubricating oil dropwise and then paste it.

2.Go to the place where the computer is repaired and ask for some silicone grease. Wipe the old silicone grease on the heat sink and CPU with a paper towel, apply the new silicone grease evenly, do not apply too thick, and reinstall the heat sink and fan. Problems can usually be solved.

If you don't have the ability to do it yourself, you can directly take the machine to the place where the computer is repaired, let him use a blow gun to blow the dust inside the case for you, and then ask him to help you change the silicone grease.

3.If the problem is alleviated after replacing the silicone grease and removing the dust, but occasionally there will be an automatic shutdown. Then you are experiencing the same problem as me: the CPU heatsink is too tight or too loose, or the force is uneven.

If the temperature exceeds 70, then untie the CPU buckle to observe, if the temperature is normal, the heatsink is installed too tightly, resulting in insufficient contact with the CPU. If it is more serious when the buckle is loosened, then the heat sink is too loose.

If it's too tight; Use a screwdriver to loosen the heatsink base screws on the top of the motherboard, and if necessary, use a piece of paper to raise the bottom a little. However, it should be noted that all four screws must be tightened, otherwise it will cause uneven installation of the heat sink. You can also use pliers to adjust the buckle to reduce its bite force; If it is too loose, it is mostly the relationship of the buckle, and it is enough to adjust the buckle with pliers to make it fastened.

See if the CPU fan buckle is broken, and the heatsink is not in close contact with the CPU.

If the CPU temperature is 90 degrees, you first check whether the CPU fan is running normally If it is normal, it is still like this, just change to a copper fan As for the upgrade of Da, it is the sound of the motherboard forcibly powering off Your CPU is 90 degrees, he must be powered off to protect it, and it will have to be charged and restarted.

You can disassemble the case to see if there is a problem with the CPU fan, or take the CPU fan out, replace it with some silicone grease and reinstall the fan.

There is a good chance that the CPU fan is broken, you can take it apart to see the rotational speed and drop two drops of oil on the axle wheel.

It's very simple, you pretend to be a Master Lu.

After powering on, it mainly monitors the CPU temperature.

Then you open a few games to see how much the CPU temperature will reach.

My laptop seems to be protected at 115 degrees and turned off.

If your computer's CPU is above 110 degrees, your computer will be dark.

That's the CPU heat dissipation problem.

Just clean up the fan.

What is a reboot.

Power failure or low battery, or automatic system updates, software updates, processor self-protection system.

Excessive temperature: Generally speaking, the dust of the chassis covers the cooling fan so that the temperature cannot be discharged immediately, and the self-protection of the processor is mainly to prevent the damage caused by the high temperature of the CPU, but it can be solved by cleaning up the dust.

Power failure: One power supply can be replaced for testing.

System update: First, check whether the automatic update is enabled, and make sure that the automatic restart after update is not checked.
