The PC can be sure that it is not a physical problem, but it shuts down automatically, what to do 10

Hihackthis is recommended

Scan a log

I'll show you how.

This is the remnants of an advertising Trojan that has been removed by antivirus software, and is retained in the startup items. It has nothing to do with the sound card!

Process file: soundmix or.

Process Location: The system directory.

Program name: troj

Program Purpose: Ad spy trojan virus.

Workaround: Look in the registry and there are the following items related to:

hkey_local_machine\software\dongtian\service]

dtinstall"="c:\\windows\\system32\\"

soundmix"=" c:\\windows\\system32\\,load"

soundmix"=" c:\\windows\\system32\\,load"

hkey_users\s-1-5-21-725345543-507921405-839522115-500\software\microsoft\search assistant\acmru\5603]

Thorough removal method:

1. In the command line window, run regsvr32 u

attach]159[/attach]

After entering, the service is uninstalled successfully.

attach]160[/attach]

2. Use ewido to delete.

3. Delete the relevant entries in the registry.

Once you've rebooted, you're good to go.

Your computer will have a blue screen of death or shut down automatically due to high temperatures. You'd better buy a radiator or open the case and use a fan to blow down the cooling, and install a 360 security guard detection system. Clean up the garbage. Ensure the smooth operation of the computer, I hope it will be helpful to the landlord.

It is recommended to rule out the virus first, and then check the power supply and heat dissipation.

The point brain automatically shuts down, 1 is there is a power problem, and CPU high temperature and other hardware failures, 2There are also failures such as conflicts between viruses and Trojan software. It's a good idea to check for viruses before checking for other items.

With the official version of 360 Security Guard. Open the 360 Security Guard software - click on System Repair, click on "One-click Repair" in the lower right corner after scanning - click on the cleaning plug-in, if there is a bad comment plug-in, check the previous one. Click on "Clean Now" in the bottom right corner - in Clean System Junk.

- Cleaning up system junk. - Click on the Trojan to use the full scan function, and if you find a threatening program, click "Deal with it now" in the lower right corner.

After scanning the full disk with 360 Antivirus, the virus is immediately removed, and the computer is restarted without giving the virus a chance to write back.

In this case, you should belong to the self-protection function of the system, because there is an automatic power-off protection function in the motherboard BIOS settings, that is, when the computer is overloaded or encounters other situations that damage the CPU or system, this information will be fed back to the motherboard chip in time and react, because the BIOS is set up with this protection function, so in order to protect the CPU from damage, the system will automatically power off.

Because your computer will automatically shut down after playing for a while, I guess your computer should clean up the dust or the fan is not running very well, this situation generally occurs after the computer has been running for a period of time, causing the CPU to overheat or the CPU to be overloaded. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function. The next day it can be turned on normally because the computer temperature has dropped.

If that's the case, rule out the heat dissipation problem!

If you can't turn on normally after powering off (your computer can turn on normally after cooling down), it is estimated that there is something wrong with the hardware or system files.

First, use the replacement method to troubleshoot the hardware problem (mainly check the motherboard and power supply).

After the hardware is eliminated, it is a system problem, and it can only be solved by reinstalling the system.

The computer is broken.

1.The power supply is broken.

2.The fan heater is broken, causing the CPU temperature to be too high, and the self-protection power is turned off.

3.There is an electric melt on the motherboard that has exploded or bulged, and it can be seen with the naked eye.

4.Virus.

After ruling out the problem of the virus, it should be caused by your CPU temperature being too high, use the software to check the CPU temperature. For example, Master Lu and everest

Hello Eliminate problems with indoor voltage and socket quality.

The shutdown is mainly caused by insufficient power of the power supply or high hardware temperatureThe power supply is not enough to replace the power supply (the market price of ordinary power supply is 80 yuan, and the better one will be more expensive) The temperature (graphics card temperature, motherboard temperature and other hardware) is too high The motherboard protects itself, so the shutdown solution: coat the CPU with a layer of silicone that is, heat dissipation glue The market price is 2 yuan, and at the same time, clean up the dust of the CPU fan.

Lubricate the fan shaft.

Not yet to replace the fan.

The solution is these, if you don't understand the specifics, you can hi me to talk about it in detail——— drifting with the wind.

Can you be more detailed about the question?

For example: whether the screen reacts when powered on.

After booting up, whether the motherboard is monitored.

Boot up to which step to shut down.

Universal Solution:

Disassemble the main chassis:

1. Remove the memory module and erase it with an eraser. (Note: If there is too much dust in the chassis, it is recommended to remove the dust).

2. Remove the BIOS battery of the motherboard, connect the metal to the BIOS battery base, and put down the power. Then attach the battery.

Try the above methods, and they can generally solve the problem. If not, describe the problem in as much detail as possible and help you solve it.

If you don't install the timer shutdown software, (if the timer shutdown software works, the time will be quite accurate, and there will be no difference of ten seconds between up and down, that is, the regularity is strong).

That is, the power supply voltage where you are not stable, everyone uses electricity to cook when the voltage is low, it may be lower than 180V or lower, buy a good wide voltage power supply, or install a voltage regulator, it's good, do it immediately, you can't deal with it, it will damage the computer, it is a hard disk.

Remove the motherboard battery and put it back in a few minutes to try.
