The computer cannot be turned on after automatically shutting down, so unplug the power cord and rep

Causes and solutions:

2. Cable problem (replug in, check VGA or DVI interface) 3. Display problem (check whether the electrical socket is powered on, if convenient, connect it to other computers to see if it is normal).

If you check that there is no virus in the system, it can only be a heat dissipation problem, and after a long time, you can open the case and carefully sweep the dust inside, and add a little high-grade oil to the fan. The main problem is to reduce the temperature inside the chassis.

If there is a problem with the power supply or the socket is not in good contact with the power cord, there will be voltage instability and automatic shutdown, you check it. In addition to overheating, this phenomenon will also occur, check the CPU, the graphics card temperature to see if it is too high, especially when playing large games, it will automatically shut down. You'd better clean up the console and replug the hardware to make sure it's in good contact.

In what state will it automatically shut down?,Are you using the motherboard of Hua S?,My machine also has this situation.,It's automatically turned off when the Warcraft picture is played.,It's estimated that the temperature is too high.,The motherboard automatically loses power.,Detect the heat dissipation of the CPU and graphics card,See if the fan is slowing down.,Remove a piece of the chassis board and try again.,There's no big problem with me dealing with it like this.。

The static electricity is too severe, and it is recommended that the chassis be grounded.

This looks like the main engine is short-circuited, so I recommend that you ground the chassis.

My colleague's computer always has this problem, and after disassembling it for a long time, we thought it was a capacitor or a certain inductor or something like a problem, and finally changed the power supply and everything was OK.

Plug in the power supply and the computer will automatically turn on, usually there are two possibilities:

1. Poor quality of the motherboard or power supply.

If the power supply or motherboard is not of good quality, when the host is connected to the power supply, an instantaneous inrush current will be generated, which may make the power supply mistaken for a power signal, resulting in automatic power on as soon as the power is turned on.

2. The BIOS settings of the motherboard are incorrect.

There is a "Power Management Setup" setting item in the motherboard BIOS, in which you can select the status of the computer when the power is re-powered after an unexpected power failure, which can be divided into auto-power-on, keep the shutdown state, maintain the state before the power off, and set the auto-boot to OFF.

Generally, this will happen when the motherboard battery is dead. If you change the battery, it's a motherboard problem. You have to repair the motherboard to solve it. However, it does not affect the use of the motherboard.

Press del when you boot up, enter the CMOS settings, power option, there is a loss power, which means that the operation is operated after the power is off, and it is good to change it to off.

One: There is a problem with the boot button; Two: There is a problem with the motherboard.
