I can t enter the system, the screen keeps black, and a cursor is flashing

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

First, the computer is poisoned, or caused by software conflicts: You can try to enter the safe mode, recall whether you have installed any software and then this situation, or what has become like this after you have been on it. If it is a software problem or after updating the system patch, directly install the installed software in the control panel, or uninstall the system patch directly and restart the computer.

If it is caused by a virus, launch the antivirus software directly in safe mode and perform a full scan.

Second, the computer is connected to an external device: the common one is to connect a USB flash drive. Unplug the external device and try it.

Three, repair by PE. Reboot, enter the BIOS, select the USB flash drive to boot, and enter the PE system. After entering, fix the system problem, or rebuild the C disk MBR

Fourth, hardware problems, hard disk and memory are relatively likely to be solved, it is recommended to replace the test or contact the manufacturer to solve.

Have you changed anything recently, such as drivers, or installed any software?

1. Restart the computer, press F8, and the selection menu will appear.

2. Select the last correct configuration, try the safe mode, if you can enter the safe mode, you can uninstall the recently installed software or driver.

The reason is that the computer is looking for a boot file, which may be caused by the lack of a boot file in the system. You can do this by following these steps: If your computer has recently reinstalled the system and the BIOS is not set back to boot from the hard drive, you will encounter this problem.

The connection between accessories, memory, graphics card, etc. and the motherboard is incorrect or loose, resulting in poor contact, which is the main reason for the black screen failure.

There are many reasons for the black screen of the computer to turn on and only the cursor is flashing, which can be summarized as follows: the poor heat dissipation of the display, power supply and CPU generate a lot of heat during work, so it is very important to maintain good ventilation, if the monitor is overheated, it will lead to color, image distortion and even shorten the life of the monitor.

Fault analysis: Sometimes the power and reset of some poor quality chassis are easy to get stuck inside or have an internal short circuit, resulting in the button being always connected, repeatedly turning on or restarting, and causing the illusion that the computer cannot be turned on.

If the computer screen is still black, it is recommended to replace the motherboard; If the system installs software and updates patches that cause a black screen, you can try to uninstall the update file; After installing the software on the computer, restarting the update causes a black screen and waits for the update to be completed. Enter the safe mode to repair the computer, wheel washingIf you can't enter the safe mode, please reinstall the system.

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

Was your last computer at least from years ago? At that time, the first frame of the computer turned on was the information of the graphics card. Then the information of the motherboard.

The motherboard information is generally displayed on 2 screens. Then enter the system. Later computers (actually motherboards) have replaced the motherboard information with the motherboard logo, such as:

ASUS, when it is turned on, it displays a frame ** on the big ASUS, and there is other information, etc. Generally, you can see the motherboard information by pressing the tab button. Nowadays, motherboard manufacturers use motherboard logos instead of motherboard information frames (advertise yourself, hehe), if your computer is okay elsewhere, it's OK, this is normal.
