HP computers always turn off automatically. What happened?

Regarding the problem that HP computers always shut down automatically, there may be many netizens who are not quite sure what is going on. So I'll tell you the reason why HP computers always shut down automatically and the solution. I hope I can help you!

HP computers always turn off automatically. Solution 1:

The first case: the graphics card is faulty.

If the graphics card fails or is damaged, it is possible that the win7 Ultimate computer will automatically shut down as mentioned above. You might as well pay more attention when using the computer every day. Generally, if there is something wrong with the graphics card, the computer will give some warnings.

The second case: the voltage of AGP slot is insufficient.

Insufficient voltage is the second biggest reason why our win7 flagship computer automatically shuts down. Just like we use electricity, if the voltage is insufficient, the computer can't run and the computer will shut down automatically.

The third situation: compatibility issues.

Compatibility has always been a long-standing problem in windows system. The graphics card in win7 flagship computer is not compatible with other software and equipment, which may easily lead to the automatic shutdown of the computer.

Secondly:

First, check whether it is caused by hardware problems, and check the reset of power supply, memory cpu and fan chassis respectively. If you don't know anything about computer hardware, it is recommended to take it to a professional computer repair point for inspection and maintenance. Don't operate it by hand, or the hardware without problems will cause you problems.

Check whether the temperature of cpu, graphics card, hard disk and motherboard is too high, and the computer always shuts down automatically. You can add a real-time temperature monitoring floating window on the desktop to detect whether it exceeds the normal temperature of computer hardware at any time. The operation method is as follows:

Open "Settings" of Kingsguard, enter the tab of the floating window, and check "Display hardware temperature". When the temperature of your computer hardware exceeds the normal temperature, the computer hardware temperature in the floating window will turn red.

Then check whether it is caused by Trojan horse virus. Please download Kingsoft Guard to kill Trojans immediately.

1. Enter the main interface to kill Trojans.

2, and then click on the quick scan.

Finally, check whether it is caused by some application software settings, such as downloading application software and antivirus software. , and then check whether the automatic shutdown task is set in the scheduled task.

HP computers always turn off automatically. Solution 2:

1, you can touch the main chassis first to see if it is very hot. Open the case cover to see if the host power supply and CPU radiator are not working.

Generally speaking, if the computer temperature is too high, the hardware will turn on protective measures and automatically shut down. The same is true of notebooks, which is very common.

2. If the fan doesn't work, it is recommended to replace it immediately. After we open the chassis, we need to see if the motherboard capacitor is burnt out. If the capacitor burns out obviously, it is recommended to replace the motherboard.

Before doing the first two steps, we can try to plug the power cord in the back tightly. If the cable tray is of poor quality, it is recommended to change it to see if the computer can be restarted.

4. If you still restart, this is probably a system failure. It is recommended to reinstall the system immediately or restore it with one button. After reinstalling, download the latest antivirus software and upgrade to the latest virus database for killing. And make the latest security patches.

5. Another reason why the computer shuts down automatically is that the voltage of your computer is unstable. If the above steps are ineffective, it is recommended to try your computer on another occasion. The voltage at home in some old communities is sometimes unstable. If it is a new community, or the voltage at home is ok, you can try to change the host power supply. If the power supply of the host computer still doesn't work, it may be that your motherboard has been broken down by voltage. We have to change the motherboard.

6. There is another situation, that is, there is something wrong with your reset button, and it will automatically restart when it is ready. Generally speaking, these are the only situations.
