Why does our home computer always lose power all of a sudden

Since it is good to change the power supply, it should be that the power supply is too small, and I have encountered this situation before, and it is enough to change to a high-power one of 300-450w.

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated, whether the CPU fan rack is stable, if it is broken or unstable, the CPU fan cannot be suppressed, the CPU fan heat dissipation capacity is insufficient, the CPU temperature is too high, and the automatic protection function of the motherboard will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to kill the virus in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

Upstairs is talking about hardware, but have you noticed a software problem? Is it possible that your computer has been poisoned (very likely)? ,I've encountered it.,It's a restart.,Later, it's directly turned on to prepare to enter the password when it "clicks" and restarted.,It's been hard to turn on.,I'm because the voltage is unstable.,But then verified that it's not (no problem with the same building),I thought it was too hot.,I directly used an electric fan to blow the host.,Still doesn't work.,Take it to the point of sale to see.,It's a virus.,It's okay after killing.。。。

During the epidemic period, be careful! networks are easy to get poisoned.

If the voltage is unstable, buy a voltage regulator for more than 100 yuan!

The laptop has been repaired several times because of static protection, but it is still like this, and the battery is removed, or static protection, what should I do.

If the computer is always faulty because of the electrostatic protection, in this case, it is generally caused by the home electricity environment, most of them are caused by the fact that the household circuit does not have a ground wire, and the static electricity cannot be released.

Ask. I'm in the dorm, just my computer.

Follow-up. Then you take a look at your power plug and try a different one.

Notebook static electricity solution:

1. When touching the laptop, put your hand in contact with the grounded steel pipe (such as a water pipe or wet ground) for a while to let the static electricity of the body go. Avoid discharging the board from the body to the board when contacting the board, resulting in damage to the Songzu board. Especially in the dry and cold winter, we wear mostly wool chemical fiber products, which are most likely to generate static electricity.

2. After using the laptop, you can put the computer in an anti-static bag to store the dark bag that will be used to wrap the notebook in the notebook packaging.

If you can't do it, you can buy some anti-static equipment, such as anti-static bracelets, anti-static mats, etc.;

The battery is removed. Press the power button 6 times regularly, and the interval should not be too long.

That's right, the power went off suddenly...

There's a problem with the power supply!

The hardware temperature inside the chassis is too high. Try the next software, Master Lu test it. Either that, it could be your power supply problem.

That's when the system collapsed. Reinstall the system and take a look.

Clean the ash, redo the system, and change the power supply if it doesn't work.

Decisive reloading!! Save yourself the hassle.

The software is useless, it's the reason for the power supply, change the Great Wall power supply!

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, add new heat dissipation silicone grease, if the heat dissipation fan is broken, change it. If it's not a problem, it may be caused by problems with motherboard parts or power supplies, voltage instability, hard disk failure, hardware overclocking, etc., and the new hardware is incompatible. 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 All Control Panel Items Power Options Select Turn off the monitor (select Never or Set Time) Select Change the computer sleep time on the left, and select Never or select the appropriate time (Win7 system) from the drop-down list next to Make the computer sleep.

See if it's caused by the settings below.

You use Master Lu to check whether the temperature of the CPU is high, and the sudden power failure is generally due to the high temperature of the CPU to protect itself. In addition, voltage instability can also easily lead to shutdown.

Ninety percent of the reason is that there is too much dust in the case due to static electricity, you open the cover, use a pump, of course, it is best to blow the blower, blow the dust on the motherboard, on the CPU fan, inside the power supply, and so on, and the problem can be solved. If it still can't be solved, consider other reasons. If you can't solve it after you finish it, you can ask me.

I think it's a power problem, if it's a hardware problem, the computer should be restarted, not shut down!

Use Master Lu to see if the hardware temperature is too high.
