The computer suddenly crashes, and then it shuts down and can t turn it off, so you can only unplug

See if the task manager can be called up, if you can click the "user" tab, under the point "logout" (is mandatory, as long as you can call up the task manager, this can be logged out,) after logging out, in the lower left corner of the computer and then click to shut down, which is equivalent to a normal shutdown. If you can't call up the task manager, click the shutdown button on the host (that is, the boot button), if you can turn it off, it is equivalent to a normal shutdown, if you press it a few times, you can keep pressing, after a few seconds (I forgot the specific seconds), it will be forcibly shut down, not a normal shutdown, it is a forced shutdown, but compared to unplugging the power supply, it will not hurt the hard disk, because the computer has time to prepare for these few seconds.

In addition, pressing the reset button on the console (the one that restarts the one) will also restart the computer immediately, and it doesn't seem to hurt the hard drive.

Have you been pressing?

Press the shutdown button for 5 seconds to shut down the computer.

Thank you Then you can only unplug the power directly, it is recommended to take it to the maintenance department to see.

If you don't know too much, don't take it apart at will, and don't modify the system things at will.

Press the reset key, or press and hold the on/off key.

If you press and hold for a minute, you can't turn off the phone, it's a computer problem. I don't know what the problem is, it may be a power supply and host interface problem, go to the computer city and ask.

Reboot: Press F8 to select the last correct configuration to enter, and reboot the machine is OK.

Check whether the capacitors near the CPU are bulging, if so, it means that it is broken, and it is easy to increase the heat of each hardware and cause various phenomena such as reboot and crash.

If you know how to solder, you can replace the bad capacitor on the motherboard, otherwise you will send it for repair.

It is very likely to be a heat dissipation problem, because it suddenly crashes after running for a period of time, it is the motherboard that protects the CPU and stops working, and it can only be turned on normally after a while of heat dissipation, and the temperature around the CPU is too high after a long time, resulting in damage to some capacitors, so the time to wait is getting longer and longer.

The computer card can not be turned off may be your computer has a serious virus or Trojan horse, or your computer configuration is too low, there is also a possibility that your system has lost some files, and unplugging the power itself is not harmful to the hardware, when the point may affect the loss of files, but if the computer is just a card and not a crash, I think there is no need to forcibly shut down, or it is better to shut down in the start menu, although it is a card but the shutdown time is a little longer, you need to wait.

Suddenly it's very stuck.,It's poisoned.,It's been very stuck.,It's a configuration problem.,Try rooting memory.,Redo the system.。 If the machine is old, it's normal, replace it.

After powering on, you can't enter the system or often crash after entering the system, and you can't use the on/off keys to shut down, you can only unplug the power supply, and the fault phenomenon is still the same after restarting;

There are three possibilities for such a failure:

1. Host power supply.

Generally, the components in the power supply voltage regulation circuit are aging and cannot play a role in voltage stabilization;

Second, the main board. It is generally caused by the poor characteristics of the boot circuit on the motherboard;

3. Memory sticks.

The main reasons are:

1. The memory module is damaged;

2. Goldfinger pollution;

3. The contact with the memory tank is not close;

4. There is too much dust in the memory tank;

It is recommended that the landlord check item by item.

It's hot, the heat dissipation of the CPU is not good, overheating protection, open the case, take off the CPU fan, put a little silicone grease on the bottom (there is a sale, 5 yuan a bottle), and put it on.

If such a problem arises, the driver is not suitable, or the system problem is caused, can you restore the system, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If the shutdown is slow or the shutdown problem cannot be resolved temporarily, the shutdown is done. Right-click on the taskbar, select Task Manager, hold down the Ctrl key and do not move, click "Shutdown" and "Close" on the Task Manager page with the mouse, then release the hand that presses the Ctrl key to wait for the shutdown.

In terms of hardware, the CPU and other hardware temperatures are too high, inappropriate hardware is installed, inappropriate things are installed before the accident, and the operation time is too long to do the number of keys, so the computer is very stuck, etc., if you have any questions, ask me.

System problems just start the power supply on it.
