The computer will suddenly shut down within 5 to a few hours after turning it on, and then press the

If you use the computer for a long time, your practice is to restart the computer for a period of time and it's okay to play, you can do this repeatedly, restart the computer is to release the cache, the cache is not junk files, of course, the time is too long, you can also use antivirus software to clean up junk files, but the most important thing mentioned earlier.

What are you doing on your computer when it's turned off, can you tell us about it? I'll tell you what you say more accurately.

Generally, shutdown is caused by a computer card, and the computer should not operate at full capacity, that is, when playing games, watching **, **, and watching web pages at the same time, it is most likely to crash and shut down while doing other operations, so don't operate other things when playing games, watching, and watching web pages.

No matter what you're doing, as soon as there is a sign of a card, stop what you're doing and quit the trial, so it won't shut down, and if so, don't play or watch it.

Hardware: If the memory is small** memory module, whether the hard disk has bad sectors, whether the hardware is incompatible or faulty, use Master Lu to test whether the temperature of the CPU and other hardware is high.

90% of the automatic shutdown is caused by the improper use of the computer by yourself, the card is the root cause of the shutdown, it is easy to cause the operation of the card not to do, it will avoid the shutdown or less automatic shutdown.

Win78 can run the most basic is 4G memory,XP is 2G memory,It's easy to double,If you don't use this number,It is recommended to add memory (this is the number of practice,Not the number of theory)。

If you have any questions, please ask me.

You can first rule out whether there is a scheduled shutdown software.

If not, consider whether there is a virus or a temperature problem.

1. Use the computer manager hardware to test the temperature of the CPU, graphics card, and hard disk when playing games to see if the temperature is too high and automatically shut down, if the temperature is too high, you need to clean up the dust of the host, and place the host in a ventilated place.

2. Whether the power supply quota is too small, resulting in insufficient voltage, whether it is too close to the quota of the power supply or exceeded. If it is a problem with the power supply, the power supply needs to be replaced.

Power issues or power button issues.

There is no problem from the configuration point of view, there is no mutual incompatibility, most of the cases of this automatic shutdown are power supply problems or system problems, starting from these two aspects, if not, you need to take the chassis to the computer city to ask professionals to check the hardware one by one.

If it is automatically turned off just after it is turned on, or it has nothing to do with the long or short boot time; There are many general failures in the operating system; Just follow 4;

If there is a regular situation, such as 30 or 40 minutes after the shutdown; Generally, there are many components of hardware failure; Just follow 3;

Computer failures such as computer failure to turn on, freeze, black screen, blue screen, restart, and stuck operation can be solved according to the following items:

1. First of all, check the power supply; 220V AC power supply (plug and socket are usually called); Then check the output voltage of the computer power supply (desktop, check the fan of the power supply, the laptop can listen carefully to the CPU, graphics card, etc. in the machine.

whether the fan is rotating);

2. See if the computer can "self-test"; If you can self-test, you can generally reinstall the operating system;

3. If it is a black screen, focus on the inspection parts (including all the causes of the black screen):

cpu；Mainboard; Memory; Graphics; display (desktop display); power supply (there is an output but the supply voltage is incomplete); and the plug-in parts and connecting wires of the above-mentioned parts;

4. Check and remove the virus, reset the BIOS, and reinstall the operating system. Reminder, if the fault persists after reinstalling the operating system and it is confirmed that there is no virus, you should consider replacing the operating system disk and trying again. In addition, after the system is installed, it is best to complete the patch before using it; to reduce the threat of viruses.

The cause of this fault is that there is too much dust inside the host, resulting in poor heat dissipation. During operation, the temperature rises gradually, and a forced shutdown is performed when the temperature protection threshold is reached.

After the power is turned off, it cannot be turned on when the temperature does not drop to the safe range. As the temperature gradually drops, out of the protective area, it is ready to be turned on again.

Workaround:1Check and clean the dust inside the case, with a focus on the CPU, graphics card, and chip cooler.

2.Check the operation of each cooling fan.

1.First of all, troubleshoot the software and reinstall the system.

2.If the temperature of each hardware is normal, think about the power supply problem first, and try another place3It may be the motherboard, try replacing the motherboard.

4.Hard disk reason, try to replace the hard disk.

5.For the reason of the memory module, try to replace the memory module.

6.For graphics card reasons, try to change the graphics card.

There are all possibilities, so I can only say give it a try.

It is possible that the CPU temperature is too high, if it is automatically powered off, you can test the CPU temperature with your hands. AMD's CPU fans are best served with a heatsink with copper pipes, as shown in the picture below. AMD's CPU has always been a lot of heat.

The new computer, it's not out of insurance, hurry up and go to the insurance, put it in the seller's place, and let them test it. Replacement tests are best.

In this case, it can be determined that it is a power supply problem. Replace the power supply and it will be normal.

If you have a virus, reinstall the system, or restore the system.

Automatic shutdown is a problem with your power supply.
