After the computer shuts down automatically, it can t be opened, and the screen is black, and the cu

This is obviously the case when shutting down during partitioning, and the system needs to be reinstalled on the USB flash drive.

Then the cause should be hardware factors, such as memory, hard disk, CPU temperature is too high, etc.

If you want to solve the problem, let's analyze it according to the above.

In this case, it is recommended to take a look at the system first. The more common thing is that the system boot is lost, and it can be repaired again. In the serious case, the south bridge is faulty, and the input and output devices are not recognized. This situation requires the motherboard to be repaired.

When your computer has such a situation, don't operate blindly because you are in a hurry, because your blind operation may cause the system to completely collapse, and there is no room for recovery. So, first of all, think calmly about whether you have done anything before, or what you have browsed. Because this situation is likely to be caused by a virus, the virus deletes your system's partition table or system boot file, and such a problem may occur.

We first have to reboot it, keep pressing the F8 key when you turn it on, if you keep pressing it and then a black background and white text menu appears, then fortunately, it means that your system is not in trouble. We enter the safe mode of the system, after which we enter the antivirus and repair the missing system files. Then reboot the machine, maybe the problem will be solved smoothly.

If you keep pressing F8 and nothing happens, it means that the problem with the computer is more serious. If you have a backup of your system before, there may be a chance to survive. Reboot,I kept pressing the up and down keys of the keyboard before turning it on,If a system selection menu appears,It means that the problem is still not big,It's just a system problem,Not a hardware problem。

Select Enter Restore to perform a system restore. After the restoration, of course, it can be turned on smoothly.

If you can't wake up the black flasher interface no matter what key you press, the problem is terminally ill. At this point, it cannot be concluded that it is a hardware problem, and it may be possible to solve it through software operation. This is where you may need a PE system.

Reboot, enter the BIOS, select the USB flash drive to boot, and enter the PE system. After entering, fix the system problem, or antivirus, or repair. After the repair is completed and the computer is restarted, the problem may be solved.

If you enter the PE system, also restore the system, or even reinstall the system in PE, but it is still like this after booting, then you need to be somewhat mentally prepared. Because it's probably a hardware issue. But at this point, it is not enough to send it for repair, you can disassemble the chassis, remove the hard disk cable, memory, graphics card, CPU, and other large hardware, wipe it, and then install it, you must be careful, and you can't violently disassemble the machine because of anxiety, because if you damage a certain hardware, then there is no way.

This is a risky operation, but it may solve the problem by trying. If this is the case, then after you reinstall it, you may be able to reboot the computer and the problem will be solved.

What should I do if I can't start the system?

Hello, listening to your description, it seems to be a failure to boot the system. It's in the Command Prompt environment. The system is on the screen, and there should be a text explanation that something is wrong.

If there is only one cursor on the screen, there is no text description, and the POST sound is normal, then it may be a problem with the hard disk.

If there is a problem with the graphics card, it is estimated that it can also enter the system, and the estimated reason is due to the memory, and your user eraser erases the gold finger of the memory, which is estimated to solve the problem. Is it normal for you to reinstall the system? Whether you use GOST or not, it has something to do with the system, take a look at your startup items.

What system are you pressing F8 to select the last boot to see.
