The computer restarts 3 times in 15 minutes, is the voltage not enough, or what other reason 10

There are too many reasons to restart.

If you have just bought a computer, it is recommended to go directly to the computer dealer who sold it to replace it.

If it has been used for a long time, it exceeds the warranty and replacement period.

You can consider the problem of power supply, because the power supply is unstable, resulting in insufficient voltage.

It could also be the CPU fan, which caused heat dissipation issues and caused the computer to restart.

In addition, memory incompatibility can also cause the computer to restart repeatedly.

These problems generally appear on assembled computers, because they have not undergone rigorous compatibility testing, resulting in incompatible system hardware and causing restarts.

There are many reasons for computer restart, and computer viruses can also cause computers to restart repeatedly, which should be analyzed on a case-by-case basis.

Two reasons. One is: the reason why the voltage is not enough. The other is: the fan of the main unit is too dirty. Just use a hair dryer to blow it. But use cold air.

My computer has just been repaired, and it's also that problem, I carefully checked the power key, and found that the wire end is in poor contact, and after soldering, I ensure that its insulation effect is now normal, you can look at the power button and the restart button, whether the socket they are connected to the motherboard is normal, and I have been poisoned before, and there have been frequent reboots, so it depends on whether the landlord can redo the system.

The last time I read it in a book, it was like this, and so was his computer, so it must be the following cases! 1: There is static electricity in the chassis

2: CPU overclocking, high temperature

3: It's just that the voltage is unstable, that's all, or you can try it first!

Please see if the silicone grease between your CPU and heatsink has hardened. There should be a certain softness.

Method 1: If there is no alarm sound when the computer is turned on, there is no self-test phenomenon when the computer starts. It's really hard to tell. But generally with the motherboard. cpu.The COMS setting error is related to the power supply.

Method 2: If the fan can start, the motherboard will be powered normally.

The system can't boot, first check if the CPU is normal. You can remove the CPU and put it on another computer that can run normally, but if it can't start, the CPU is broken. It can start, indicating that it is not the reason for the CPU.

Method 3: The power switch is faulty, when the power switch button cannot be reset in time after pressing the power switch button due to aging, so that the switch is always in the ON state, then there will be a phenomenon that the host starts to start after powering on the power switch when the power switch is pressed, but it will automatically shut down after 4 seconds.

I've been in this situation too, but it's Windows 7 OS!

Since you have opened the computer at low voltage, it is very likely that it has caused the bad sector of the hard disk, it is recommended to check it with relevant software (such as hdtune), if it is a logical bad sector, it can be repaired, but if it is a physical bad sector, it is not easy to do, it can only be isolated to prevent the bad sector from further expanding!

Secondly, there is a high possibility that you may have caused a certain startup file to be corrupted or lost during the operation, so it took a long time to cause the computer to boot up on this startup item! You can try to restore the system by using the system disk.

You can use software like 360 Security Guard to see the startup problem first! If you really have no choice but to reinstall the system!!

Hope it helps, good luck!!

Please pay attention to check the bad sectors of the hard disk, it is not because of the boot failure, which causes the boot system area to appear in the bad sector, which causes boot difficulties.

I think the system files are missing or wrong.

Disk damage will appear at boot and normal time card, if so, see the method below.

This is an illegal shutdown or other reason that causes the disk to be damaged, please fix it (fix it for each disk or only fix C).

Built-in disk repair method:

The specific steps are as follows: select the drive letter in my computer, right-click to select the properties, select "Tools Start Checking" in the pop-up drive properties window, and select "Automatically repair file system errors" and "Scan and recover bad sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing it according to the above method, a box will pop up, the point is, repair it after the automatic shutdown, win78 select the disk check button according to the plan).

If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it).

A voltage regulator for refrigerators is sufficient. Or go buy a UPS with voltage stabilization
