My computer always shuts down automatically, I changed the CPU, the fan case, and the silicon coatin

If the motherboard capacitor doesn't burst the pulp, it's most likely a power supply issue.

#...What would be the effect of that? If you don't understand, please don't ask here. Let's go find someone to test it. Ask here will have many answers. It may cause you to change your entire computer.

There are many reasons for automatic shutdown, and generally speaking, as long as the CPU is not too hot, there is no need to touch it, because it is very unlikely to have a problem. The main thing is the motherboard, the old motherboard is prone to capacitor bursting, or the power supply is insufficient! When playing big games, it shuts down, but sometimes it just restarts!

If it is turned off directly, generally speaking, the power supply is more, if your computer has two memory, it is best to use one first, sometimes the bad two memory together will also shut down or restart!

Check whether the capacitors of the motherboard and graphics card are broken.

There are the following reasons for automatic shutdown.

1. The temperature is too high.

If there is a problem with the heat dissipation of the computer itself, then when we use it for a long time, ghost

Win7 system will be prone to reboot failure, these are not conducive to the normal operation and use of win7 system, if the computer can not dissipate heat independently, you can place a small fan on the chassis position, this problem is easier to solve.

2. The power supply is unstable.

When the power supply is unstable or there is a problem with the connection, the win7 system will start the self-protection mode, that is, it will automatically restart, then win7 users should make sure that the computer power connection is normal.

3. The memory module is unstable.

If the memory module is unstable or loose, it is easy to cause the computer to automatically restart the fault, which can be solved by this method: first open the case, then remove the memory module, wipe the memory module and put the gold finger, it is best to clean it up, and then reinstall it back.

4. Hardware compatibility.

When there is a problem with the compatibility of the hardware, it is easy to cause the computer to restart frequently and fail, and this kind of fault will be relatively troublesome in the process of solving, and the incompatible computer hardware needs to be replaced.

Hello, I'm glad to answer for you, I hope it will be helpful to you.

There are many reasons why the computer frequently freezes, restarts and shuts down,1Caused by viruses, it is recommended to try a full antivirus, 2

There is an error in the system file, it is recommended to reinstall the system.

There is a conflict between software and hardware.

Or some software is incompatible with the system.

It is caused by reinstalling the system or driver, 4CPU temperature is too high, or other hardware temperature is too high.

Clean the lower chassis dust.

Switch to a larger fan.

Pay attention to heat dissipation. This is important.

Temperatures that are too high can also cause the system to run too slowly.

5. "Crashes" caused by the exhaustion of subsystem resources, such as often.

The CPU usage is 100/100, so you can open as few programs as possible or replace the CPU to increase the memory.

6. Caused by pirated software.

Please delete. 7. The hard disk has bad sectors, try to repair it.

The BIOS is not set up correctly, or the crash is caused by unsuccessful overclocking.

You can remove the motherboard battery and discharge it.

Let the BIOS settings revert to their default values.

9. Crash caused by other reasons.

For example, the voltage is unstable.

The memory quality is not up to par.

The ability of the optical drive to read the disc is reduced, the quality of the floppy disk is poor, and so on.

Caused by the operator's misoperation.

-Fei Ō type noisy Fei Answer--- Plagiarism is shameful--- plagiarism must be reported--- thank you--- I wish you a happy and healthy rent.

After the crash, you have to wait for a pin to be matched before you can turn it on, which must be caused by the high temperature of the CPU, sell it.

In terms of hardware, you already know how to lower the CPU temperature.

But software is also very important, don't run what you don't need to run. You can reinstall the system to see if it freezes when it is bare.

First of all, automatic shutdown is not necessarily the cause of CPU overheating, there may be other hardware problems, or even software problems, and then touch the silicone is a technical job, generally if you do it yourself, it is better to get it in vain, many friends like to win by quantity when applying silicone grease, in fact, this is to push the CPU into the fire pit, in fact, the current excellent fan has been designed very reasonably, the contact between the heat sink and the CPU core is very good, The correct way is to remove the gum in the silicone grease (this thing is the most harmful) and add a little (very little is enough, about 1 3 of a drop of water) on the CPU core, and then use a slightly hard piece of paper (magazine color page) to scrape the silicone grease on the core, wipe evenly, and the thickness of the silicone grease is controlled in the naked eye invisible white is appropriate.

However, if you apply it too thinly, it will be uneven and leave air bubbles, so it is better to apply a little more, and then use a heat sink to drag the air bubbles back and forth on it, so that there is very little silicone grease left.

In fact, it's better not to wipe it yourself.

When the CPU temperature is too high, it will automatically shut down, you touch your fan heatsink to see if the heatsink will be very hot, if it is very hot, it means that the heat of the CPU is too high.

The heatsink does not take away the heat from the CPU instantly.

At this point, change to a fan with a higher fan speed, or a heat sink with a higher heat dissipation, such as a heat sink with heat pipes or a copper heat sink.

If the heatsink is not hot, it means that your fan heatsink is not in full contact with the CPU, and you need to remove the heatsink and reassemble it.

When reinstalling, you should first wipe off the silicone on the CPU and metal heat sink, and then apply the silicone to the thickness of the heat sink about the thickness of a fingernail.

After locking, gently shake the cooling fan by hand to avoid shaking.

There was no such thing last summer. Is there a period of inactivity? It is normal for the temperature to be high in summer, but some minor problems can cause the heat to be dissipated in time.

Full love robbery 2 at a time, try.

Take the computer and get it back up again.

Hello, please analyze and solve it 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.

If it helps, please choose the answer you are satisfied with!!

In that case, let's change the CPU cooler, such as the "Kyushu Fengshen Icewing 5". **On 180 or so**.

If it's a game that overheats and crashes, then there's no way to do it, the machine is always in this situation, maybe the CPU is broken, but there's no need to change it, let him cool down, and he will use it.

The CPU doesn't burn. He was overheated. So after a while, the computer will automatically shut down.

Because the fan may be broken. Not 100 percent. It's not worth the money.

Less than $10. You can clear the CMOS and try it.。。 Next to the battery.

It is a needle angle handle of three. There's a little seat on it. 3 eyes.

Take him down and change it for 2 needles to try. Wait 30 minutes. I change back to the previous two stitches.。

If it's not good to make. Ha ha. Take it and fix it.

I don't have much money. Ha ha.

Maybe it's the weather. The CPU temperature is too high and it will also restart. Remove the lid and use it.

Pretend to be a Master Lu to see if the hardware temperature is overheating protection.

Let's see if the capacitor of your motherboard has burst...
