Windows 11 computers may occasionally encounter some problems. The blue and black screens on Windows are two common examples. In this guide, however, we shall focus on the black screen on Windows 11 before and after log in. So, if you have encountered this problem, you should read on for the most effective solutions. Let us get to it.

What Causes the Black Screen on Windows 11

From our experience and communication with a number of users, we find that the most common triggers of this black screen problem are the following:

  • An explorer.exe crash
  • Third-party software conflicts
  • Corrupted system files
  • Hardware problems

You may try the solutions below to fix the black screen on Windows 11 before or after log in.

1. Restart the Computer

A system reboot should be the first call for most people. When you restart the computer, you will force most processes to shut down automatically. If some of these processes are problematic or contain bugs, the black screen will be resolved on startup. This solution will be effective for instances of the black screen before and after log in.

2. Start the Computer in Safe Mode

Starting a computer in safe mode is a very effective solution for the black screen problem because it enables the computer to start with only the essential set of drivers and resources. This way, conflicting programs or processes that trigger the error are eliminated. You may enter Safe Mode using the following steps.

1. Press and hold the power button till the computer is forced to shut down.

2. Press the power button, and once you see the Windows logo, hold the power button again until the computer shuts down. Repeat this 3 times, and on the fourth attempt, allow Windows to start normally.

3. Click the Advanced options button, then navigate Troubleshoot, Advanced options, Startup Settings, and click the Restart button.

4. Press your F4 key to enter Safe Mode. Now, you may start programs one after the other to eliminate the one that triggers the black screen.

3. Ensure there are No Problems With Ports and Cables

When your computer enters a black screen, there are chances that you are dealing with some bad ports or connecting cables. If a port or cable is faulty, it may disrupt the signal between your device and its monitor. Also, a bad cable may degrade the signal quality, leading to the black screen.

If you have devices plugged into a bad port, it may also cause signals that the computer can not interpret, leading to the black screen before or after log in. To fix this problem, unplug all peripheral devices and ensure no cables are loosely connected or bad.

4. Scan for Virus

Many computer problems are triggered by malware infections on your computer. A black screen may clearly indicate that the computer has viruses, and you must run a malware scan to remedy this problem.

You may use third-party antivirus like norton, mcafee, kaspersky and avast or you can use the built-in Windows Security.

1. Click the Search lens on the Taskbar, type Security, and click Windows Security.

6. Update the OS

Bugs in the operating system may trigger the black screen on Windows 11. A great solution to fix the issue is updating your OS. An OS update will also include driver updates, and this may come in handy if the graphics drivers are outdated, as they may also contribute to the black screen problem.

3. Right-click the Windows Explorer process and click Restart.

Above, we explained how updates will come with bug fixes and the latest drivers.

When this happens, it is often because the update has bugs that are triggering the problem. In that case, rolling back your updates will fix it.

1. Press Windows + I to open the Settings app.
