系統問題
If there is a problem with your computer system, such as the installed patch is incompatible, or the software is incompatible, or the driver is incompatible, or the system itself is missing some files, it will cause a black screen.
If it is a system failure, there are two ways to solve it. The first method is to shut down the computer and then restart it. At the same time, press and hold the F8 key on your keyboard to enter the advanced startup options.
After entering the advanced startup options, select Perform Last Known Good Configuration from your advanced startup options. Then press Enter. After the execution is completed, you can enter the system.
Monitor problem
First, check whether the black screen when the computer is turned on is caused by the monitor's refresh frequency being set too high. After entering safe mode, right-click the desktop and select "Properties", and select the "Settings" tab in the window that opens. Click the "Advanced" button, select the "Monitor" tab, and set the "Screen Refresh Rate" lower.
If the problem still cannot be solved, consider whether there is a problem with the graphics card driver. Uninstall the graphics card driver in safe mode and reinstall it. In addition, the system may be infected with viruses, which may also cause this phenomenon. It is recommended to clean the system in safe mode.
Methods/Steps:
1
/5
The hard disk may not be set as the startup disk, causing the system to fail to load. First, we need to enter the bios interface. Press F10 and a dialog box will pop up. Select "Y" to save the current settings.
2 The connection cable between the computer hard disk and the host is loose. We can plug it in with the boot disk first and see if we can enter the pe tool. If we cannot enter the pe tool, it means there is something wrong with the motherboard. Check if there are any obvious signs of damage on the motherboard.
3 There is a problem with system booting
Insert the boot disk into the computer, select to boot from the USB flash drive, and after entering the USB flash drive, select a PE to enter.
4 After entering, find the tool windows startup boot repair in pe, click it, select C drive after entering, and click automatic repair.
5 prompts that the repair is successful, the system boot has been successfully repaired, and you can restart the computer to enter the system.
1. There are many reasons for the black screen on the computer, but generally speaking, it is a failure of hardware and software. Let’s analyze the hardware failure first. For hardware, first check whether the hardware interface wiring inside the computer host is loose, and re-plug and unplug it, such as the graphics card interface.
2. Check whether the motherboard is burned. Generally, if the capacitors on the motherboard are hot and a little black and scorched, it may be that the motherboard is burned. It is recommended to take it to a professional repairman for inspection. Under normal circumstances, the fan will not turn on if the motherboard is burned out. Check it yourself.
3. Of course, it is not ruled out that the computer power supply is burned out or the computer current is unstable. Users can use the power supply to test whether the power supply is burned out.
If you can hear the startup sound, it means there is no problem with the system. So use the following methods to troubleshoot the cause and see what color the monitor power light is (take the Dell monitor as an example): The light is not on - the power supply cord is not energized. Check to see if the socket plug is loose, or the plug to the monitor is loose. . Plug it in again and see if it still doesn't light up. Maybe the power cord is broken. If it still doesn't light up after changing a good wire, then the monitor is broken and you need to either repair it or buy it. If the yellow light is on - it means there is no digital signal, re-plug the serial port cable between the host and the monitor to see if it still doesn't work, the serial port cable may be broken; if the green light is on - it means the digital signal is normal, but the screen is still black. There are two reasons for this:
1. The system setting resolution is too high and the display does not support it and the screen is black (but this black screen display will pop up a prompt). The solution is to restart in safe mode and lower the resolution and then restart the system to increase it;
2. The system was pirated and the anti-piracy patch was accidentally downloaded and turned into a black screen at startup. Solution: Do not download patches after reinstalling the system.
Method 1: Restart explorer.exe
1. At this time, the computer black screen has entered the system desktop, but it is not displayed. Use the keyboard to press Ctrl+Alt+Del. In the interface that appears, select "Start Task Manager".
2. In the Task Manager interface that appears, click the "File" option and click "Run New Task" that appears.
3. When the run window appears, enter "explorer.exe" and press Enter to confirm. Then the computer returned to normal.
Method 2. Reinstall the system
Many times method 1 cannot completely solve the black screen problem. The screen is still black when you open it for the second time. What should you do? Refer to the following operations to reinstall the system.
01 Prepare a USB flash drive of 4g or above. Before using the USB flash drive, you need to clear or transfer all the files in the USB flash drive.
02 Insert the prepared USB disk into another computer and open the Cloud Knight Installation Master. After opening, Cloud Knight will automatically configure the user's computer information and select the startup USB disk interface.
03 Then you enter the system selection interface. Here you can see options for various versions of windows xp windows7 windows8 windows10. Here we take windows10 as an example. There are various versions of the system for the user to choose from. Select installation here. Home version 64-bit system, then click to start production.
04 To create a USB bootable disk, you need to clear all the files in the selected USB disk. If there is any data, please back up the files yourself before starting the creation. After the backup is completed, return to the production screen and click OK.
05 Next, Cloud Knight will start downloading the system. At the same time, if you want to change the system to download, you can click Cancel Production to cancel the replacement. The system file downloaded here is large, please be patient.
06 After the production is completed, you can click to preview and simulate the U disk boot interface. Make a note of the U disk startup shortcut keys prompted by the Cloud Knight interface.
07 Insert the prepared USB disk into the faulty computer, restart the computer, and press the startup hotkey just recorded. Enter the U disk boot. If there is a Please select boot device selection interface, select the UEFI USB boot option. Enter the system boot options interface and select Windows 10 PE to enter the system.
08 After entering the system, the Cloud Knight software opens the search system image, finds the image, and clicks to install. No changes are required in the preparation for installation interface. Click Start Installation and select Continue. Waiting for installation.
09 After the installation is completed, remove the USB flash drive and click Restart Now.
10 No further operations are required, just wait patiently for the system to be installed. After the installation is completed, enter the system to complete the reinstallation.
The computer cannot be turned on and the screen is black and there is a beeping sound. This is usually due to the board card:
1. The board card has poor contact. Pull out the memory module and independent graphics card, wipe the golden finger with an eraser to remove the oxide layer, and then re-insert it firmly.
2. The board is damaged. In other words, the memory module or graphics card is damaged and needs to be purchased new.
3. The slot is damaged. Take the memory stick as an example. Pull out the memory stick and insert it into another slot. If it can boot normally, then the memory slot of the motherboard is damaged.
4. CPU fan failure. If the CPU fan accumulates too much dust, please clear the fan dust; if the CPU fan does not rotate, please replace it.
5. The CPU or CPU fan is not installed correctly. Remove the CPU and CPU fan and re-insert them correctly, especially making sure that the CPU pins are installed correctly.
6. If none of the above reasons are the case, it may be the motherboard. If you know how to install the host yourself, you can remove the motherboard and install it on another computer to test whether it can run normally; if you don't know how to install the host, go directly to a computer repair shop for testing.
