If the computer has a completely black screen but you can see the mouse pointer after turning on the computer, it is usually caused by abnormal system files, drivers or settings, rather than hardware corruption. 1. You can try to enter safe mode. If it can be displayed normally, it may be a driver or software conflict. You should uninstall the recently installed graphics card driver or security software; 2. Check whether the Explorer crashes, and you can run explorer.exe through the Task Manager. If it occurs frequently, you need to check for viruses or hard disk problems; 3. Use the system file repair tool to execute the sfc /scannow and DISM commands to repair the system files; 4. Troubleshoot hardware problems, such as replacing the monitor, plugging and unplugging the graphics card, updating the BIOS or switching the display mode. Follow the above steps to investigate, most cases can be solved. If it is invalid, consider reinstalling the system or sending the inspection hardware to repair.

When the computer is turned on, the screen is completely black but the mouse pointer can be seen. Usually, Windows encounters problems during startup. Although this problem seems serious, it does not necessarily mean hardware damage. It is often caused by abnormal system files, drivers or settings.

Here are some common reasons and corresponding solutions for your investigation:

1. Enter safe mode to check whether it is normal

Sometimes third-party software or driver conflicts will cause the desktop to fail to load, but only the most basic components are loaded in safe mode, which usually displays the desktop normally.

How to operate:

• Force shutdown three times (long press the power button), the "recovery environment" may be entered during the 4th normal power boot
• Or press F8 repeatedly during normal startup (some models may be Shift F8) to try to call up advanced startup options
• After entering "Safe Mode", you can see if you can see the desktop normally

If you can enter safe mode normally, it is likely that it is caused by a certain driver or software conflict. Next you can:

• Uninstall recently installed graphics card driver or other hardware driver
• Disable or uninstall recently installed security software or optimization tools

2. Check whether the Explorer crashes

A common reason for the black screen but a mouse is that Windows Explorer (explorer.exe) does not start normally.

Solution steps:

• Press Ctrl Shift Esc to open Task Manager
• Click "File" > "Run new task"
• Enter explorer.exe and press Enter

If this can restore normalcy, it means that the explorer crashed temporarily. If you often encounter this situation, you can check:

• Is there any virus or malware interference
• Is there any problem with the hard disk (especially the system disk)

3. Try using the system file repair tool

Corrupt system files may also lead to black screen problems, especially if the update fails or sudden power outages.

It is recommended to execute the following command:

• Open Command Prompt in Safe Mode (Admin)
• Enter the following command and execute it one by one:
  • sfc /scannow
  • DISM /Online /Cleanup-Image /ScanHealth
  • DISM /Online /Cleanup-Image /RestoreHealth

These commands scan and repair system files. Restart after completion to see if the problem is solved.

4. Consider hardware or display related issues

Although not common, it can also be a hardware problem, such as a graphics card failure or a loose monitor connection.

You can try the following:

• Replace the monitor and test it
• Plug and unplug the graphics card (if it is a discrete graphics card)
• Update BIOS or motherboard drivers
• If it is a laptop, try to connect the external monitor to see if there is a picture

In addition, you can also try to switch resolution or refresh rate:

• Press Win Ctrl Alt 向左/向右方向鍵
• Or adjust the display settings in safe mode

Basically these common inspection methods. The problem of black screen with a cursor is not too complicated, but it is easy to make people anxious. Follow the above method step by step, and the reason can be found in most cases. If you have tried all of them but haven't solved it, you may want to consider reinstalling the system or sending the repair and testing hardware.
