Why does my computer keep restarting for no reason? Computers are fine in the repair shop and don t

It should be a bad heat dissipation, open the case, clean up the CPU inside, the dust on the graphics card fan and the power supply, if it doesn't work, you have to replace the CPU fan with a little more power, there are a lot of problems recently, all of them were used in the past, the fan power is small, and cheap accessories are used for heat dissipation, in addition to the current online games, the computer has been running for a long time, useless system garbage, more dust, running large online games, etc., the CPU occupies a lot, and it can't be quickly dissipated, Causes the CPU temperature to be too high, causing the computer to restart automatically!

After a period of restart, it is generally related to heat dissipation, and there are more common, hard disk problems can not be ruled out, if the hard disk has bad sectors or bad sectors will also cause reboot phenomenon.

What I said upstairs still makes sense.

You try to take all the parts out of the computer and put them back on, and try it, because it's static electricity or it's a bad contact.

Please analyze and solve the problem from the following aspects.

1 Computer poisoning or malware may also cause computer abnormalities, the solution is to upgrade the anti-virus software, anti-virus, if it really doesn't work, reinstall or restore the system. Reinstalling or restoring the system can completely resolve the software side of the problem.

2. Unreasonable configuration, uncoordinated, and incorrect BIOS settings will also cause computer abnormalities, so you should find more professional personnel to solve the problem when installing or upgrading hardware. You can send the configuration down to help you see if the configuration is reasonable.

3 The high temperature of the computer will also cause the computer to be abnormal, it is recommended to use Master Lu software to measure the temperature of the hardware, and then solve it.

4. Due to the voltage instability point, the power supply is not enough, and it will often cause computer abnormalities, if it is caused by these reasons, configure a voltage regulator, and replace the high-power power supply to solve the problem.

5 Caused by running large software and programs, such as playing big games, using large software, watching Blu-ray movies, etc., it should be caused by poor computer hardware configuration. The only solution is to upgrade the computer configuration and optimize the computer system.

6 Old computer Because there is too much dust in the case, it is easy to cause computer abnormalities caused by short circuits. Clean the inside of the chassis frequently.

7 Old computer Due to the long period of use, the capacitance of the motherboard circuit is aging, which will also cause abnormal problems in the computer. Only sent for repair or replacement.

8 Old computer hard disk will also fail after a long time, causing the computer to crash, which requires the use of hard disk testing software to test the hard disk, repartitioning the installation system can repair the hard disk logical bad sectors, can not be repaired, and only to replace the hard disk.

Reboot failures don't happen for no reason, right, what did you do before restarting? What hardware has been upgraded? You can elaborate on that.

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.

2. The CPU or other hardware temperature is too high, and the memory and graphics 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 repartition and reinstall the system.

4. Power failure and voltage instability can also cause automatic restart.

5. Incompatible drivers can also lead to restart.

6. Failure of motherboard parts.

7. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the check mark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

8. If the above methods are ineffective and you can't find the problem, it is recommended to overhaul it.

Go to the Device Manager and check if there are any conflicting places with the various drivers, and if there are any yellow ones! If there is a possibility that the device driver is incompatible with the system; Then delete the drivers of the sound card, graphics card, network card and other devices, and then install the drivers one by one, restart the computer every time you install a device, to check which device's driver caused the failure, find out, ** the new version of the driver of the faulty device, and then install it. Then clean the dust in the computer, clean the gold finger of the memory, graphics card and other equipment, and reinstall the memory and other equipment.

As you described. Automatic restart, there are generally three cases:

1. There is an instability problem in the power supply of the motherboard or power supply. There may be a hardware problem with the device itself, and you'd better leave it on for standby last night to see how it goes. If there is only a certain period of time, then it is necessary to check whether the voltage in the home is unstable.

2. Another computer is infected with malicious programs and Trojans. You only need to clean up the primary partition system data thoroughly, and you should be fine if you redo the system.

3. If the machine is too dirty, it may also cause; In particular, pay attention to whether the CPU fan in the main chassis is rotating, and the heat dissipation will not keep up.
