How to fix black screen after login on Windows?

The black screen after a computer logs in is usually not a hardware problem, but a result of a conflict in the system, driver or software. 1. First determine whether it is a "fake black screen". You can try to open Task Manager through Ctrl Shift Esc. If there is no "Windows Explorer" process, run explorer.exe to restore the desktop. 2. Update or rollback the graphics card driver, press Win Ctrl Shift B to refresh the driver, or uninstall/rollback the graphics card driver in safe mode. 3. Troubleshoot third-party software interference, disable startup items through the task manager, or check conflicting software one by one using Clean Boot. 4. Check whether the display settings are abnormal, try to connect to the external monitor and switch the display mode, and go to "Settings" → "System" → "Display" to adjust the resolution and multi-monitor configuration. In most cases, the above methods can solve the black screen problem. If it occurs repeatedly, further check the system file integrity or hardware status.

The screen turns black after logging in to the computer, which is a headache. But don't worry, this situation is usually not caused by a system, driver or software conflict. Key inspection directions: display settings abnormal, graphics card driver problems, resource manager crashes, and third-party software interference.

1. Check if it is just a "fake black screen"

Sometimes you think the screen is black, but in fact it is just that the desktop is not loading. Try the following steps first:

• Press Ctrl Shift Esc to open the task manager directly (if it can be opened, it means the system is still running)
• See if there is "Windows Explorer" in the process list
• If not, click "File" → "Run new task", enter explorer.exe to enter

This method is suitable for black screens caused by unexpected crash of Explorer, which is often caused by updates or system stuttering.

2. Update or rollback the graphics card driver

Problems with the graphics card driver are common reasons for black screens, especially after the driver is updated.

You can do this:

• Press Win Ctrl Shift B shortcut key to force refresh the graphics card driver (you will see the screen flash for a short time)
• Enter safe mode to uninstall or roll back the graphics card driver:
  • Press Win R to enter devmgmt.msc to open the device manager
  • Expand "Show Adapter", right-click your graphics card → Uninstall the device or select "Driver Rollback" in "Properties"

It is recommended to use the official website driver or try to update automatically through the device manager.

3. Check for third-party software interference

Some security software, optimization tools or antivirus software may interfere with the system's operation in the startup item, resulting in the desktop being unable to load normally after logging in.

You can try:

• Switch to the Startup tab in Task Manager and disable unnecessary startup items
• Use Clean Boot to troubleshoot conflict software:
  • Press Win R to enter msconfig → “Services” to check “Hide all Microsoft services” → Disable all
  • Go to the "Startup" tab → Open Task Manager → Disable all startup items
  • After restarting, see if it returns to normal

If there is no problem with clean startup, it is basically a problem with a third-party software.

4. Display settings or resolution abnormality

Sometimes the display settings are changed incorrectly, which can also cause the phenomenon of looking like a black screen.

You can try:

• Plug in the external monitor to see if there is a picture (press Win P to switch the display mode)
• If there is an external screen display, it means there is a problem with the built-in monitor settings.
• After logging in, try pressing Win D to see if the desktop can be called up, or press Win Tab to see if the window preview exists

At this time, you can go to "Settings" → "System" → "Display" to check whether the resolution and multi-monitor settings are correct.

Basically these common ways of dealing with it. In many cases, it can be solved by restarting, but if it occurs repeatedly, you have to check the integrity of the driver or system file.
