Windows 11/10中遇到黑屏问题，以下可能有助于解决问题。我们将讨论三种不同的场景。第一个是您可以登录计算机但没有任何显示。另一种情况是您甚至无法登录计算机并看到黑屏。这篇文章将向您展示如何在登录后解决Windows 11/10 空白^(Blank)或黑屏^{(Black Screen)}问题——无论有没有光标，在启动时。Windows 11/10卡在黑屏上，它也会对您有所帮助。

^{(Fix Black Screen)}Windows 11/10中的黑屏死机^(Death)问题

这里有一些场景，我们将检查您可以在每个场景中遵循的故障排除步骤：

1. 登录前开机黑屏
2. ^(Black)登录Windows PC后黑屏
3. 从睡眠模式唤醒电脑后屏幕一直黑屏^{(Screen stays black after waking computer from Sleep Mode)}
4. 使用鼠标滚动时屏幕变黑
5. 重新启动 PC 后出现带有旋转点的黑色^(Black)或彩色屏幕
6. ^{(Black Screen)}Windows 升级^{(Windows Upgrade)}或安装^{(Installation)}期间的黑屏
7. 安装新程序时出现黑屏^{(Black Screen when installing new programs)}。

作为一般的第一步，按WinKey+Ctrl+Shift+B键盘快捷键重新启动显示驱动程序^{(restart your Display driver)}，看看是否有帮助。如果没有，那么您也可以使用Microsoft的在线^(Microsoft)黑屏疑难解答，看看是否有帮助。如果没有，请继续阅读以了解具体的故障排除建议。

^{(Black Screen)}登录前开机黑屏

1]检查所有连接

确保^(Make)所有电缆均已插入并牢固固定；您的显示监视器在物理上已打开等。

2]尝试唤醒设备

按^(Press)CapsLock或NumLock键，查看按键上方的状态灯是否亮起。如果您连接了键盘，请按WinKey+Ctrl Shift+B。如果您处于平板电脑模式，请在 2 秒内同时按下音量增大和音量减小按钮 3 次。

Windows 11/10中的黑屏问题而无法登录，则可能是驱动程序问题，或者投影可能会自动设置到其他设备，例如第二台显示器或电视。您将需要Windows 安装介质^{(Windows Installation Media)}。

在正常工作的计算机上，下载安装^{(Installation)}介质并将其刻录到USB或DVD。将媒体连接到问题计算机，将其关闭并使用安装媒体启动。询问时，选择修复此计算机^{(Repair This Computer)}。您将看到一个选择选项^{(Select an option)}屏幕，其中包含继续Windows 10、关闭^(Shut)计算机和排除^{(Troubleshoot)}计算机故障的选项。选择计算机疑难解答^{(Troubleshoot computer)}。选择高级选项^{(Advanced Options)}。单击启动设置^{(Startup Settings)}，然后单击重新启动^(Restart)。当计算机重新启动时，您将获得一些选项。按 F5^{(Press F5)}或滚动到带网络的安全模式，^{(Safe Mode with Networking)}然后按Enter进入安全模式^{(Safe Mode)}。

3]检查默认显示

进入安全^(Safe)模式后，您必须检查连接到计算机的不同显示器。Press Windows Key + P调出显示列表（见上图）。尝试选择选项以将显示器移动到其他连接的显示器，例如电视或第二台显示器。如果您选择电视，请确保电视已连接并已打开。检查电视是否设置为接收来自计算机的信号。如果电视显示显示，当您按下 Windows键^(Key)和 P时，通过在列出的设备中选择当前计算机显示器作为默认显示来更正显示。

PS：如果按Windows Key + P没有弹出侧边栏，您可以从Control Panel > Display > Project to a Second Screen获取它。

4]卸载显示^(Display)设备驱动程序^{(Device Driver)}并自动安装^{(Auto-install)}

如果上述方法不起作用，请使用安装^{(Installation)}介质再次启动并进入安全^(Safe)模式。使用上述步骤 2.1 至 2.5 卸载显示设备驱动程序。

您可能还需要确保 Windows 11/10 支持您的显卡。

5]隔离设备导致问题

如果设备管理器^{(Device Manager)}中有多个显示驱动程序，

1. 禁用所有这些，除了一个。
2. 在没有安装媒体的情况下重新启动以查看问题是否已解决。
3. 如果没有，请使用安装媒体重新启动并再次进入安全模式^{(Safe Mode)}。
4. 这一次，禁用您之前遗漏的驱动程序并启用另一个驱动程序。
5. 再次^(Again)在没有安装媒体的情况下重新启动以查看是否有效；这称为设备驱动程序的隔离；您只需一次启用一个驱动程序并检查它是否工作，直到找到导致问题的驱动程序。
6. 找到它后，将其禁用并联系该设备的制造商以获取更新。

^(Black)登录Windows 10 PC后黑屏

我们将讨论的另一种情况是您可以登录时，然后屏幕变为空白。

您要尝试的第一件事是按Ctrl+Alt+Del并查看它是否会调出Task Manager。如果是这样，那就太好了。单击^(Click)文件File > Run新任务。键入explorer.exe并按Enter。当我遇到这个问题时，这对我有用。^{( issue.)}

如果这对您不起作用，请拔下并移除所有外部设备^{(unplug & remove all external devices)}并重新启动。如果可以显示，则可能意味着其中一个外部硬件导致了问题。如果是这种情况，请开始一个接一个地插入外部设备，直到失去显示为止。卸下您插入的最后一个设备，看看是否可以恢复显示。如果是，请在联系设备制造商之前不要使用该硬件设备。再次检查其他外部设备。

如果移除外部设备不能解决问题，请转到安全模式^{(Safe Mode)}。由于我们假设您在登录之前而不是在您登录之后才能获得显示，因此您必须重新启动计算机。在锁定屏幕上，单击显示屏左下方的电源图标。在按住SHIFT的同时，单击RESTART。这将使您的计算机重新启动。重新启动后，您将获得一些选项 - 选择带网络模式的^(Networking)安全模式^{(Safe Mode)}。您只需在屏幕上按 F5 即可进入安全模式^{(Safe Mode)}。

如果不是重新启动，而是显示一个包含三个选项的屏幕：继续Windows 10；故障排除^{(Troubleshoot)}；和关机^(Shutdown)，点击疑难解答^{(Troubleshoot)}，然后点击高级^(Advanced)。然后单击启动设置^{(Startup Settings)}，然后单击重新启动^(Restart)。计算机重新启动时将显示进入安全模式的选项。^{(Safe Mode)}

现在，当Windows 安全模式^{(Windows Safe Mode)}执行以下操作时：

1]检查^(Check)是否选择了正确的显示

查看显示器是否设置为其他设备。从控制面板^{(Control Panel)}中，选择显示^(Display)。在Display^(Display)窗口的左侧，选择Project to a Second Display。右侧会出现一个侧边栏，显示连接到计算机的显示器列表（见下图）。检查是否选择了正确的显示^{(Check to see if the correct display is selected)}。如果不是，请纠正它。Windows 11/10中的黑屏问题。

2]重新安装^(Reinstall)或回滚显示驱动程序^{(Display Driver)}

我们必须重新安装或回滚显示驱动程序^{(reinstall or rollback the Display Driver)}。打开设备管理器^{(Device Manager)}并删除显示驱动程序^{(Display Driver)}。

• 单击^(Click)搜索栏并输入“设备管理器”（不带引号）
• 从出现的列表中，单击更新设备驱动程序^{(Update Device Drivers)}以打开设备管理器^{(Device Manager)}窗口
• 在设备管理器^{(Device Manager)}窗口中，找到并单击以展开显示^(Display) 适配器^(Adapters)
• 右键单击^{(Right-click)}显示适配器驱动程序^{(Display Adaptor Driver)}，然后单击卸载
• 重新启动以再次自动安装驱动程序。

这应该可以为您解决黑屏问题。

3]关闭RunOnce进程

Fix Black Screen of Death in Windows 11/10; Stuck on Black Screen

If you are fаcing black screen problems in Windows 11/10, the following maу help fix the issue. There are three different scenarios that we are going to talk about. The first is when уou can log in to уоur computer and don’t get any display. The other scenario is when уоu can’t even sign into the computer and see a black sсreen. This post will show you how to resolve Windоws 11/10 Blank or Black Screen рroblems after login – with or without the cursor, on boot. It will also help you if Windows 11/10 is stuck on a black screen.

Fix Black Screen of Death problems in Windows 11/10

There are scenarios here, and we will check out the troubleshooting steps you can follow in each of them:

1. Black Screen on boot before signing in
2. Black screen after signing into Windows PC
3. Screen stays black after waking computer from Sleep Mode
4. Screen goes black when Scrolling with Mouse
5. Black or colored screen with spinning dots after restarting your PC
6. Black Screen during a Windows Upgrade or Installation
7. Black Screen when installing new programs.

As a general first step, press WinKey+Ctrl+Shift+B keyboard shortcuts to restart your Display driver and see if that helps. If it doesn’t, then you can also use the online Black Screen Troubleshooter from Microsoft and see if that helps. If it doesn’t, then read on to learn about the specific troubleshooting suggestions.

Black Screen on boot before signing in

1] Check all your connections

Make sure that all your cables are inserted and fixed firmly; your display monitor is turned on, etc., physically.

2] Try to wake the device

Press the CapsLock or NumLock key to see if the status light above the key turns on. If you have a keyboard connected, press WinKey+Ctrl Shift+B. If you’re in tablet mode, simultaneously press the volume-up and volume-down buttons three times within 2 seconds.

If you are not able to sign in because of the black screen problem in Windows 11/10, it could be a driver issue or the projection could be automatically set to a different device such as a second monitor or a TV. You will need Windows Installation Media.

On a working computer, download and burn the Installation media to USB or DVD. Connect the media to the problem computer, turn it off and boot using the installation media. When asked, select Repair This Computer. You will get a Select an option screen with options to continue to Windows 10, Shut down the computer, and Troubleshoot computer. Select Troubleshoot computer. Select Advanced Options. Click on Startup Settings and then on Restart. When the computer reboots, you will get some options. Press F5 or scroll to Safe Mode with Networking and press Enter to enter Safe Mode.

3] Check the Default Display

Once in the Safe mode, you have to check the different displays attached to the computer. Press Windows Key + P to bring up the display list (see image above). Try selecting options to move the display to other attached displays such as a TV or a second monitor. If you select TV, make sure TV is connected and turned on. Check the TV to see if it is set to receive signals from your computer. If the TV shows display, correct the display by selecting the current computer monitor as a default display in the listed devices when you press Windows Key with P.

PS: If pressing Windows Key + P does not bring up a sidebar, you can get it from Control Panel > Display > Project to a Second Screen.

4] Uninstall the Device Driver for Display and Auto-install

If the above does not work, boot again using the Installation media and go to the Safe mode. Uninstall the device driver for display using steps 2.1 to 2.5 mentioned above.

You might also want to ensure that Windows 11/10 supports your graphics card.

5] Isolate Device causing problem

If there are more than one display driver in Device Manager,

1. Disable all of them except one.
2. Reboot without installation media to see if the issue is fixed.
3. If not, reboot with installation media and go to Safe Mode again.
4. This time, disable the one that you left out earlier and enable another driver.
5. Again reboot without installation media to see if that worked; This is called isolation of device driver; You simply enable one driver at a time and check if it worked until you find the driver that is causing problems.
6. Once you find it, keep it disabled and contact the manufacturer of that device for updates.

Black screen after signing into Windows 10 PC

The other scenario we will talk about is when you can log in, and then the screen goes blank.

The first thing you want to try is to press Ctrl+Alt+Del and see if it brings up the Task Manager. If it does, great. Click on File > Run new task. Type explorer.exe and hit Enter. This worked for me once when I faced this issue.

If this does not work for you, unplug & remove all external devices and reboot. If you can get a display, it might mean that one of the external hardware is causing the problem. If that is the case, start plugging in external devices one by one until you lose the display. Remove the last device you plugged in and see if you get the display back. If yes, don’t use that hardware device until you contact the device’s manufacturer. Check again with other external devices.

If removing external devices does not fix the issue, go to the Safe Mode. Since we assume that you are getting display until you sign in and not after you sign in, you will have to reboot your computer. At the lock screen, click on the power icon towards the bottom left of the display. While holding down SHIFT, click on RESTART. This will make your computer reboot. After the reboot, you are given some options – select Safe Mode with Networking mode. You can simply press F5 on the screen to enter Safe Mode.

If instead of a reboot, you are presented with a screen having three options: Continue to Windows 10; Troubleshoot; and Shutdown, click on Troubleshoot and then on Advanced. Then click on Startup Settings and then Restart. The option to enter Safe Mode will be presented when the computer reboots.

Now, when Windows Safe Mode do the following:

1] Check to see if the correct display is selected

See if the display is set to some other device. From Control Panel, select Display. On the left side of the Display window, select Project to a Second Display. A sidebar will appear towards the right and show you a list of displays connected to the computer (see image below). Check to see if the correct display is selected. If not, correct it. Else continue with troubleshooting blank screen problems in Windows 11/10.

2] Reinstall or rollback the Display Driver

We have to reinstall or rollback the Display Driver. Open Device Manager and remove the Display Driver.

• Click on search bar and type “device manager” without quotes
• From the list that appears, click on Update Device Drivers to bring on the Device Manager window
• In the Device Manager window, locate and click to expand Display Adapters
• Right-click on the Display Adaptor Driver and click on Uninstall
• Reboot to auto-install the drivers again.

This should fix the issue of a black screen for you.

3] Close RunOnce processes

Open Task Manager. If you see a RunOnce32.exe or RunOnce.exe, stop the Process or Service.

Though a tedious process, the above should fix black screen problems in Windows 11/10.

Black Screen during a Windows Upgrade or Installation

In the rare eventuality that you get a Black Screen while upgrading to or installing Windows, you can try and see if any of the following troubleshooting steps help you.

The reasons for getting a black screen during the upgrade could be many. It could be a hardware problem, a driver problem, or a multiple video output issue.

First, please see if you meet the Hardware requirements. If you meet them, you can try and see if any one of these help you:

• Restart your PC in safe mode and select Enable low-resolution video option.
• The video output may have switched to an alternate port when the driver was re-installed during online configuration. So please check for multiple video ports on your computer.
• Please also check for display output during BIOS POST. If the POST logo or text is not being displayed on-screen then the issue could be with the hardware.
• Boot the computer in safe mode by pressing F8 on restart. You may receive a message, on a restart, that Windows could not complete the installation. Open command prompt, type devmgmt.msc and hit enter to open the Device Manager. Here disable Display Adapter. On restart, the installation should complete OK. Do remember to update the Display Adapter settings again, later.
• If you have a second monitor, unplug it, from your graphic card and see if it helps.
• If your video card has two DVI outputs, try plugging the monitor into the one you’re not currently using.
• Maybe your BIOS is old and you need to flash upgrade it.
