您可能会遇到 Windows 10 计算机无法识别显示器^(Monitor)、键盘^(Keyboard)或鼠标^(Mouse)的情况。在本文中，我们将建议您自己解决问题的方法，然后再联系技术支持人员。

电脑^(Computer)无法识别显示器^(Monitor)、键盘^(Keyboard)或鼠标^(Mouse)

您可以采取以下措施来解决 Windows 10 计算机无法识别显示器^(Monitor)、键盘^(Keyboard)或鼠标的情况：

1. 修复电源问题
2. 管理驱动程序

让我们详细谈谈它们。

1]修复电源问题

如果您正在设置您的计算机，但您的CPU无法识别显示器^(Monitor)、键盘^(Keyboard)或鼠标^(Mouse)，您可能会遇到电源^(Power)问题。您可以执行这些操作来解决此问题。

• 卸下可能位于主板顶部的^{(Motherboard)}CMOS 电池^{(CMOS Battery)}，重新连接它，看看它是否能解决问题。
• 取下电源线^{(Remove Powercord)}30 分钟，将其重新插入，看看是否能解决问题。
• 切换您的PSU。电源单元^{(Power Supply Unit)}将交流电转换为计算机内部组件所需的低压直流电。因此，如果它发生故障，则任何外部设备都无法正常工作。
• 如果您无法解决问题，请尝试通过移除每个可移动部件（例如额外的硬盘驱动器^{(Hard Drive)}、内存^(RAM)）将错误归结为单个组件。许多用户能够通过更换RAM来解决此问题。

2]管理驱动程序

如果您的计算机仍然无法识别外接显示器、键盘或鼠标，请尝试管理它们各自的驱动程序。您需要查看的驱动程序是：

• 显示适配器
• 监视器
• 键盘
• 鼠标和其他指针设备。

回滚驱动程序

修复错误的第一件事是回滚^{(Roll Back)}驱动程序。为此，请通过 Win + X > Device Manager, 设备管理 ^{(Device Manager )}器，展开 显示驱动程序， ^{(Display Driver, )}右键单击您的图形驱动程序^(Driver)，然后选择属性。 ^{(Properties. )}转到 驱动程序 ^(Drivers )选项卡，然后单击 回滚驱动程序。^{(Roll Back Driver.)}

如果该选项显示为灰色，则您的驱动程序未更新，因此，请尝试更新它。

更新驱动程序

要更新驱动程序，请打开 设备管理器， ^{(Device Manager, )}展开 显示驱动程序， ^{(Display Driver, )}右键单击图形驱动程序^(Driver)，然后选择更新驱动程序。 ^{(Update Driver. )}

按照屏幕上的说明更新您的驱动程序

重新安装驱动程序

要重新安装驱动程序，请打开 设备管理器， ^{(Device Manager, )}展开 显示驱动程序， ^{(Display Driver, )}右键单击图形驱动程序^(Driver)，然后选择卸载设备。 ^{(Uninstall Device. )}

现在，拔下并重新插入设备并检查它是否解决了问题。

现在，如果您也遇到任何问题，请对键盘^(Keyboard)和鼠标驱动程序执行相同的操作。^(Mouse)

如果您仍然面临外部显示器^{(External Monitor)}的任何问题，请查看此故障排除指南^{(troubleshooting guide)}。
