The computer will be powered off after 3 minutes of playing! The computer suddenly lost power, and i

Check the power supply. Is it that the power cord is not plugged in properly, or the voltage is unstable or something. What is your electricity environment, if the temperature is too low, the computer will not work. Check to see if the cables of the various parts of your computer are well connected.

CPU cooling fan, clean it up, is it bad contact, or there is dust in it or something. CPU heat dissipation is also crucial.

You open the side panel of the case, put the memory module inside, if there are two, leave one, discrete the graphics card, discrete the sound card or something (you are a CPU integrated graphics card), do a minimization test to see, keep the CPU, a memory module, a hard disk, a monitor, and a power supply. If there is no problem with these and you can bring them, then it means that these hardware are fine.

If you have two memory sticks, swap them back and forth to see if they all work.

You see if there are any settings in your BIOS, boot F10 into the BIOS and restore the default value under the BIOS. If that's not enough.

Call 800, or look for after-sales service, I hope it will help you.

Hope mine is helpful to you.

1.Software (don't say I'm talking nonsense, really, 1 year ago, I installed Rising at home and started with the computer, and it popped up in less than 3 seconds (into the desktop) to upgrade, and it was restarted, and then the repairman entered the safe mode and unloaded Rising on the fine.

2.Virus, virus may cause automatic shutdown (now the virus is too powerful) 3Hardware, go to the local computer maintenance department, or the headquarters to check, at least know more than us.

It is recommended that you turn on the computer less, and the motherboard will burn if the power is often off.

4.(Not recommended) don't play the game when you turn it on, wait to see what happens to the computer half a minute before the machine.

5.There is no blue screen (1 second) when it is turned off

6.Reinstall the system.

Sometimes you can't just think about hardware, you have to think about software as well.

There is a problem with the CPU heat dissipation, it may be that the fan is in poor contact, you can open the cleaning ash and try it.

If the computer suddenly loses power, it means that it is not shut down abnormally. The files running on the system are not stored correctly. When you turn it on again, the startup programs that the computer reads first don't run correctly, and all this time is spent looking for these programs, so it will be very slow.

There are generally several reasons for the sudden shutdown of the computer:

1. Virus causes.

2. Turn on "Automatic shutdown and restart when the computer encounters a serious error".

3. Serious memory errors cause the system to crash (software problems).

4. Malicious program or shutdown

5. Due to the heat dissipation problem of the machine (the CPU fan is not working properly, the overall temperature of the chassis is too high, etc., the CPU fan can be replaced and the chassis cover can be opened to solve the heat dissipation problem of the machine).

6. It may be that the voltage is not very stable, when the voltage is too high or drops below the minimum working voltage of the host power supply, the host will also protect and shut down.

Phenomenon: During the normal operation of the computer, the system suddenly and automatically shuts down or restarts the system.

Phenomenon analysis: Today's motherboards have a temperature monitoring function for the CPU, once the CPU temperature is too high, exceeding the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the relevant hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.

What to do: If the above sudden shutdown phenomenon keeps happening, first check whether the heat dissipation of the CPU is normal. Turn on the case to see if the fan blades are working properly, and then enter the BIOS option to see the speed of the fan and the working temperature of the CPU.

If you find that it is a fan problem, you will carry out relevant dust removal maintenance on the fan or replace it with a better quality fan. If the hardware is ruled out, enter the system to thoroughly check and kill the virus. When these factors are eliminated, the cause of the failure may be the aging or damage of the power supply, which can be confirmed by replacing the power supply method, and replace it with a new one if the power supply is broken, and it must not be used continuously, and the hardware will be burned.

If so, quickly find after-sales service to help you check it (if you change places and don't shut down, it is caused by the unstable voltage in the place where you live).

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, and add new heat dissipation silicone grease. If it is not a problem, it may be caused by problems with motherboard parts or power supply, voltage instability, hard disk failure, etc., and the new hardware is not compatible.

When the computer is turned on, the progress bar is read, and it is usually turned on and off, and there is a sound of bumping, that is, there is a virus, you can.

Two possibilities. First: the power supply is not enough, the power consumption of the graphics card increases when gaming, and the power supply is not enough, and it will automatically shut down.

Solution: Buy a power supply, rated at 300W.

Recommended: Big buffalo 400w, about 150.

Second: Your computer has been bought for a long time and has not been cleaned, and there is too much dust under the CPU fan, which causes the CPU temperature to be extremely high, and the computer shuts down due to automatic protection.

Solution: First, remove the fan, clean, if the silicone grease on the CPU is hardened, wipe some silicone grease on it, and an ultra-thin layer can be used.

Second, change the fan. Recommended: Cool Talk Sen White Knight *1 generation mute, 2 generation performance.

Is it no longer restarted, and the power will be automatically cut off. My computer used to be, the power supply was broken. Hope it helps.

The steps to resolve the situation that causes your computer to freeze are as follows:

First: the computer power supply is insufficient, the power supply voltage is unstable, etc., or the power supply is broken.

Second: Silicone grease (that is, heat dissipation paste) should be added to the CPU fan of the computer motherboard. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard, or you can change the socket to see if it is down.

First, check whether your CPU fan is still rotating, at least reach about 1800 revolutions per minute, if the fan is normal, change the power supply, the power supply of the host may be unstable.

The easiest and most thorough way to solve the problem of power supply is to replace the power supply.
