Causes and solutions to the problem of repeated computer restarts

1.The power supply is one of the biggest suspicions that causes the system to automatically restart.

When the number of devices in the system increases, the power consumption increases, and the voltage output of the inferior power supply will decrease sharply, which eventually leads to the unstable operation 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 issues can also cause the system to reboot.

There is a relatively high chance that a memory error will cause the system. 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 grid voltage can also lead to system restarts.

If your computer shares a power strip with high-power appliances such as air conditioners and refrigerators, the voltage supplied to the computer will be greatly affected when these appliances are activated, 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 with electrical outlets.

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 for system operation. The computer will restart. Solution: Choose a socket with good quality.

5.The temperature of the system is too high when it is running.

At this time, you should check whether the CPU fan is running properly 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.

6.Compatibility issues with the hardware.

It is usually caused by the compatibility of the motherboard with the memory module. But I've also come across instances where the graphics card causes the system to keep restarting.

Do you have a restore in your machine, and if so, get rid of the restore first.

If you go into safe mode, maybe you're poisoned.

My old desktop computer has been in this situation a few times, and I will use my own experience to tell you how to deal with it. There are two possibilities for this computer to restart repeatedlyHardware issues and software issues

Software problems, generally caused by system crashes, various driver errors, system failure to load and other problems cause the computer to restart and enter a dead loopAt this time, there is no other way, only to use the reinstallation system this method to solve the problem, and it is also one of our most commonly used methods.

The second is the hardware problem, there are several reasons why this hardware cannot be started, I will tell you about each of them.

The first is the memory module problem.

Because the memory module in the computer for a long time, the plug port into a certain amount of dust or the memory module has some looseness, resulting in some poor contact, the solution is actually very simple, is to open the chassis, pull the memory module from the slot, clean it with a brush, the card slot is also cleaned with a brush, you can use a hair dryer weak wind to blow it is also possible, do not use any wet towels, do not touch any water, remember, and then plug the memory module back into the slot, the computer can not start, First try this method, one of the most common problems.

The second, the power supply problem.

Because of the power supply problem can not be turned on, simply put, the power supply is insufficient, can not drive the operation of the computer, this is no good way, there is no other way than to replace the power supply, fortunately, the power supply of a computer is not expensive, two or three hundred can buy one, change one without so distress.

Third, the motherboard capacitor burns out.

I've encountered this situation, the other hardware of the computer has been checked without any problems, but it just can't start successfully, and finally the repair brother used a pen to check the motherboard and found that two capacitors were burned, and the new capacitors were re-soldered OK, is it expensive to change a capacitor? Nonono, I only spent 50 yuan on replacing two capacitors and working hours. As shown in the figure above, the capacitor is burned out, and there is obviously a bulging situation.

Fourth, the CPU is overheating.

This situation happens the most in summer, the computer suddenly shuts down automatically after a few hours of driving, and it can't be started successfully, because although there are CPU fans and power fans blowing inside the computer, but it is still impossible to avoid the occurrence of CPU overheating, the solution is also very simple, let the computer rest and rest, just cool down, and those who have money can buy a water-cooled chassis to ensure that the CPU will not overheat.

I've been in contact with the basic situation, because my own computer has encountered, first check the hardware problem, if the hardware is fine, then it must be a software problem, if it really won't, then get a professional repair computer personnel there, spend money to let people repair it for you, after all, people are professional, you add a few more hours of work this money will come out, save yourself trouble, spend money to solve the problem.

There may be one of the following reasons why your computer restarts repeatedly

1.The computer's power supply is faulty, causing the motherboard to not function properly.

2.The computer hardware is loose, causing the computer to not function properly.

3.Corrupted computer system files cause the software to not function properly.

In short, the key to restarting the computer depends on what fault amount is reported, so that you can quickly find the problem.
