有时，用户在打开计算机后会遇到黑屏或黑屏问题，甚至会听到哔声。在这种情况下，许多用户更喜欢重新启动他们的 PC，因为他们发现这在大多数情况下都有帮助。如果重启Windows(Windows)机器后问题仍然存在，则可能是计算机硬件存在问题。打开计算机后出现空白显示的原因有很多。找出问题的实际原因的最佳方法是正确排除计算机故障。
Windows 11/10 PC 打开但没有显示或蜂鸣声
如果您的 Windows 11/10 计算机打开但显示器或键盘上没有显示，请尝试这些建议来解决问题。
- 测试你的显示器
- 测试 VGA 线
- 识别哔声代码
- 执行 RAM 检查
- 移除外部硬件
- 检查显卡
- CPU和主板检查
让我们一一看看这些方法。
1]测试你的显示器
当您的 Windows 10 计算机打开但显示器或键盘上没有显示时，第一步是检查显示器。这将让您知道您的显示器是否正常工作。您将在其他故障排除方法中节省时间。首先(First)，检查电源。如果电源正常，则检查连接到显示器的任何电缆是否松动。如果所有连接都正常但显示器没有打开，请将同一显示器连接到另一台 PC。如果显示器在与另一台 PC 连接后无法打开，则为故障。
2]测试VGA线
有时，由于VGA(VGA)电缆故障，显示器在接通电源后不显示任何内容。如果您在第一种方法中发现您的显示器正常，请尝试更换VGA电缆。还要检查VGA线的接头是否损坏。如果更换VGA(VGA)电缆后显示器仍然空白，请继续使用其他故障排除方法。
3]识别哔声代码
电脑配有内置扬声器，可发出哔声。您可能在打开 PC 时听到了这种哔声。当出现问题时，计算机会发出不同模式的哔声，以便用户通过解码哔声代码来了解错误原因。您的计算机在出现问题时生成的不同类型的哔声代码(types of beep codes)列在您的计算机或主板手册中。看看你是否可以解码哔声代码。
4]执行RAM检查
在大多数情况下，RAM是打开计算机后显示器没有显示的主要原因。如果您的计算机上有两个RAM棒，请移除其中一个，然后打开您的 PC。如果您在显示器上看到显示，则您移除的RAM棒可能已损坏。要确认它，请在卸下第一个 RAM 棒后将第二个RAM棒插入同一插槽，然后打开 PC。有时 RAM(Sometimes RAM)插槽有故障。您可以通过将两个RAM棒一个接一个地插入一个插槽然后再插入另一个插槽来检查您的RAM或RAM插槽是否有故障。如果内存(RAM)棍子脏了或被腐蚀了，考虑清洁它。
5]删除外部硬件
如果您在启动时没有听到任何哔声，请尝试断开所有外部硬件设备。主板只需要CPU及其风扇、RAM和SMPS即可启动。主板不需要启动所有其他硬件，包括SSD、HDD 、外部卡和其他外部设备，包括打印机、扫描仪等。(HDD)因此，您可以删除所有这些额外的设备并启动计算机。如果计算机正常启动，请尝试将已移除的设备一一连接并每次启动。这可以让您知道哪些硬件已损坏。
6]检查显卡
有时用户会因为显卡(graphics card)损坏而出现黑屏。也许你想检查你的显卡。如果您的 PC 上没有安装显卡，则可以跳过此步骤。在这种情况下，所有图形操作都由您的主板处理。
有时，如果用户长时间没有清洁它，显卡就会腐蚀。或者灰尘会堆积在上面，导致显卡和GPU之间发生通信丢失。现在，您必须卸下显卡，然后在没有它的情况下运行您的 PC。取下显卡时请佩戴防静电腕带，以确保安全。这也将保护计算机的敏感内部组件免受静电损坏。
To run your PC without the graphics card, connect the video cable of your monitor with the video port of the motherboard (VGA/HDMI/DVI). If you get an output on the display, your graphics card may be faulty. If your graphics card is dirty or corroded, clean it using isopropyl alcohol. In most cases, graphics cards only require cleaning. After cleaning it, insert it into the respective slot and run your computer. If you do not get any output on the screen, consider replacing the graphics card.
7] CPU and Motherboard checkup
If none of the above methods work for you, your CPU or motherboard may be damaged.
In any case, if these suggestions do not help, you have to take professional support to repair the computer.

In such a case, many users prefer restarting their PC as they have fоund that this helps in most cases. If the issue still persists after rebooting thе Windows machine, there may be а problem with the comрuter’s hаrdware. Τhere are many causes for a blank display after turnіng the computеr On. The best way to find out the actual cause of the problem is to troubleshoot the computer properly.
Windows 11/10 PC turns On but no display or beeps
If your Windows 11/10 computer turns On but there is no display on the monitor or keyboard, try these suggestions to fix the issue.
- Test your monitor
- Test the VGA cable
- Identify the beep codes
- Perform a RAM checkup
- Remove external hardware
- Check the Graphics card
- CPU and Motherboard checkup
Let’s see these methods one by one.
1] Test your monitor
When your Windows 10 computer turns On but there is no display on the monitor or keyboard, the first step is to check the monitor. This will let you know whether your monitor is working properly or not. And you will save your time in other troubleshooting methods. First, check the power supply. If the power supply is OK, then check whether any cable connected to the monitor is loose or not. If all the connections are OK but the monitor is not turning On, connect the same monitor with another PC. If the monitor does not turn On after connecting with another PC, it is faulty.
2] Test the VGA cable
Sometimes, the monitor does not display anything after getting the power supply due to a faulty VGA cable. If you find your monitor OK in the first method, try replacing the VGA cable. Also, check whether the connector of the VGA cable is damaged or not. If your monitor still remains blank after replacing the VGA cable, move ahead towards other troubleshooting methods.
3] Identify the beep codes
The computer comes with a built-in speaker that creates a beep sound. You might have heard this beep sound while turning the PC On. When something goes wrong, the computer generates a different pattern of beep sound so that the user can understand the cause of the error by decoding the beep code. The different types of beep codes that your computer generates at the time of a problem are listed on your computer or motherboard manual. See if you can decode the beep code.
4] Perform a RAM checkup
In most cases, RAM is the main culprit for getting no display on the monitor after turning the computer On. If you have two RAM sticks on your computer, remove one of them and then turn On your PC. If you get a display on the monitor, the RAM stick that you have removed may be damaged. To confirm it, insert the second RAM stick in the same slot after removing the first one and then turn your PC On. Sometimes RAM slot is faulty. You can check whether your RAM or RAM slot is faulty by inserting both RAM sticks one by one in one slot and then in the other slot. If the RAM stick is dirty or corroded, consider cleaning it.
5] Remove external hardware
If you do not hear any beep sound on startup, try disconnecting all the external hardware devices. The motherboard requires only CPU and its fan, RAM, and SMPS to get started. All other hardware including SSD, HDD, external card, and other external devices, including printers, scanners, etc., are not required by the motherboard to startup. Therefore, you can remove all these extra devices and boot the computer. If the computer boots correctly, try connecting the removed devices one by one and boot each time. This lets you know which hardware has damaged.
6] Check the Graphics card
Sometimes users get a blank screen due to the damaged graphics card. Maybe you want to check your graphics card. If you do not have a graphics card installed on your PC, you can skip this step. In such a case, all the graphical operations are handled by your motherboard.
Sometimes, the graphics card corrodes if the user has not cleaned it for a long time. Or dust can accumulate on it due to which the communication loss occurs between the graphics card and the GPU. Now, you have to remove the graphics card and then run your PC without it. Please wear anti-static wrist bands while removing the graphics card for safety. This will also protect the sensitive internal components of the computer from being damaged by the static charge.
To run your PC without the graphics card, connect the video cable of your monitor with the video port of the motherboard (VGA/HDMI/DVI). If you get an output on the display, your graphics card may be faulty. If your graphics card is dirty or corroded, clean it using isopropyl alcohol. In most cases, graphics cards only require cleaning. After cleaning it, insert it into the respective slot and run your computer. If you do not get any output on the screen, consider replacing the graphics card.
7] CPU and Motherboard checkup
If none of the above methods work for you, your CPU or motherboard may be damaged.
In any case, if these suggestions do not help, you have to take professional support to repair the computer.
