很少有计算机问题(computer problems)比按下计算机上的电源按钮并看着什么也没发生更令人沮丧。您的计算机无法启动的原因有多种——一些与硬件相关，而另一些与软件相关。
您的计算机在无启动状态下可能表现出的一些明显症状包括：
- 没有操作系统声音
- 尝试启动计算机时没有信号灯
- 系统开机但Windows未完成启动
- 硬盘活动灯闪烁
- 不存在诊断代码
- 屏幕上的错误消息
- 黑屏
这些和其他症状可能表明您的计算机显卡、主引导记录、WINLOAD.EXE、主板(motherboard)、电缆或内部连接有问题。
由于现代计算机是复杂的机器，当计算机无法启动时，并不总是可以知道从哪里开始修复计算机。另外，有几种可能的硬件配置使得无法诊断所有可能的问题。
在本指南中，我们将分享基本的故障排除提示和有用的修复程序，当您的计算机无法在Windows 10中启动时，它们可以为您提供帮助。
如何修复计算机无法在 Windows 10 中启动(How to Fix Computer Won’t Boot in Windows 10)
如果您的计算机无法启动，则可能是由一些不同的原因引起的。症状(Symptoms)也有所不同。当您按下电源按钮时，您的计算机可能根本无法启动。或者它可能会打开一秒钟左右，然后再次关闭。
您的计算机可能实际上已打开，但显示为空白，或者您可能卡在BIOS设置中并且无法访问您的操作系统。这些只是计算机硬件或软件潜在问题的结果。
您可以尝试的一些快速硬件修复包括：
- 检查电源线以确认它们运行正常
- 检查电源开关以确保其打开
- 将电源线正确插入电源插座或电源，以防松动
- 排除电源线和墙壁插座后，请检查 PC 机箱内的电缆，以确保没有故障或松动的电缆。如果您有预建系统，您可能需要在打开 PC 之前联系设备制造商，以免保修失效。
- 拔下任何外部加密狗或外围设备，如USB设备或显示器连接电缆，因为这些有时会导致电源问题。如果您的计算机在未插入外围设备的情况下启动Windows 10，请尝试分别插入每个设备以测试并找出有问题的设备。
您的计算机可能正在通电但仍无法正常启动，当您按下电源按钮时它没有反应，或者它打开一秒钟然后再次关闭。如果您在计算机上看到任何这些迹象，请尝试以下修复。
6.电源按钮(Power Button)
当您的计算机无法在Windows 10(Windows 10)中启动时，电源按钮是潜在的罪魁祸首之一。如果您的计算机无法开机但主板指示灯亮起，则问题可能出在电源按钮或将其连接到主板的电线上。
如果您的主板有板载电源按钮，您也可以像使用电源按钮一样打开系统。如果这可行，则问题可能出在计算机机箱上的电源按钮上。
7.哔声和邮政编码(Beep and POST Codes)
Beep和POST（开机(Power)自检）代码是内置测试，可帮助您查明计算机无法启动的原因。(Self Test)这两个代码是音频和视觉提示，可帮助确定可能导致您的 PC 无法开机或启动的任何硬件问题。
POST代码通常表示系统在引导过程中遇到硬件问题的时间点。这样，您可以确定问题的根源。例如，如果POST代码指示内存初始化错误，则意味着您需要对RAM进行故障排除。
哔声(Beep)代码是计算机启动时听到的一系列哔声形式的音频提示。例如，三声哔声可能表示未检测到视频卡，因此您可能需要重新安装GPU以解决问题。
虽然POST和Beep代码可能有用，但每个制造商在其主板上使用不同的代码系统。您可以通过在线搜索主板制造商使用的代码或查看主板文档来确定您的计算机遇到的问题。
8. BIOS/UEFI Updates
如果没有 POST 代码，请检查您的主板的 BIOS 是否是最新的(check whether your motherboard’s BIOS is current)。即使您的计算机无法POST ，您也可以更新BIOS/UEFI。请查阅(Consult)您的主板制造商的文档或进行在线搜索，以检查您计算机系统的最新BIOS版本。
9.重新安装 PC 内的连接(Reseat Connections Within the PC)
如果您最近在计算机内部工作，或者它最近被运送到某个地方，则它的一个组件有可能在机箱内松动。
您可以通过打开计算机、卸下侧面板并检查其内部的各种连接是否正确就位来重新安装所有内容。重新安装会重新建立这些连接，通常会修复Windows 10无法启动的问题。
检查包括RAM、GPU和主板电缆在内的所有组件是否都安装在各自的插槽中。您可以通过移除每个组件并将它们重新插入来做到这一点。
如果RAM棒或GPU出现故障，请尝试在没有它们的情况下启动并查看您的计算机是否打开。
10.在另一台 PC 上测试您的硬盘(Test Your Drive on a Different PC)
如果您没有硬盘驱动器的备份，请将其取出，将其连接到USB适配器或扩展坞，然后插入另一台正常工作的计算机。如果硬盘驱动器仍在工作，您可能可以在重新安装 Windows 10(reinstalling Windows 10)或将 PC 送修之前将文件复制到外部驱动器上。
Windows 10 无法启动时的其他尝试(Other Things to Try When Windows 10 Won’t Boot)
- 检查(Check)PC 内是否有任何电气短路迹象，因为这些可能会导致您的计算机根本无法启动或损坏它。
- 测试您的电源，如果出现故障或无法正常工作，请立即更换。电源单元往往会导致计算机内部的组件选择性地或间歇性地工作。
- 用必要的硬件启动并检查计算机是否正常启动。一次重新安装每个硬件，并使用开机自检(Self Test)卡测试计算机并确定导致计算机无法完全启动的组件。
- 一旦确定有故障的硬件，请立即更换。
如果一切都失败了，请向信誉良好的计算机维修服务寻求专家建议和帮助，或联系您的计算机制造商的技术支持团队。

Windows 10 Won’t Boot? 10 Fixes to Try
Few computer problems are more frustrating than pressing the power button on your computer and watching as nothing happens. There are several reasons why your computer won’t boot – some are hardware-related, while others are software-related.
Some of the clear symptoms your computer may exhibit in a no-boot state include:
- No operating system sounds
- No signal light when you try to boot your computer
- System powers on but Windows doesn’t complete booting
- Hard drive activity light flickers
- No diagnostic codes present
- On-screen error message
- A black screen
These and other symptoms could indicate issues with your computer’s graphics card, master boot record, WINLOAD.EXE, issues with the motherboard, cables, or internal connections.
It’s not always possible to know where to start fixing your computer when it won’t boot because modern computers are complex machines. Plus, there are several possible hardware configurations making it impossible to diagnose every possible issue.
In this guide, we’ll share basic troubleshooting tips and helpful fixes that can help you when your computer won’t boot in Windows 10.
How to Fix Computer Won’t Boot in Windows 10
If your computer won’t boot, it could be caused by a few different things. Symptoms also vary. Your computer may not boot at all when you press the power button. Or it may turn on for a second or so and then turn off again.
Your computer may actually turn on but the display is blank, or you may get stuck in the BIOS settings and can’t access your operating system. These are just the results of underlying issues with the computer hardware or software.
Some quick hardware fixes you can try include:
- Checking your power cables to confirm that they’re operating properly
- Checking the power supply switch to ensure that it’s on
- Plugging in the power cable properly into the power outlet or supply in case it has become loose
- Once you rule out the power cord and wall outlet, check the cabling within the PC case to ensure there are no malfunctioning or loose cables. If you have a prebuilt system, you may want to contact the device manufacturer before opening your PC so as not to void the warranty.
- Unplugging any external dongles or peripherals like USB devices or display connections cables as these can sometimes cause power issues. If your computer boots in Windows 10 while the peripherals are unplugged, try and plug each one separately to test and find the problematic one.
Your computer may be getting power but still won’t boot properly, it doesn’t react when you press the power button, or it turns on for a second and then shuts down again. If you see any of these signs on your computer, try the following fixes.
6. Power Button
The power button is one of the potential culprits when your computer won’t boot in Windows 10. If your computer won’t power on but the motherboard light is on, the problem could be the power button or the wires that connect it to the motherboard.
You can also turn on the system the same way you would with the power button if your motherboard has an onboard power button. If this works, then the problem is likely with the power button on your computer case.
7. Beep and POST Codes
Beep and POST (Power On Self Test) codes are built-in tests that can help you pinpoint why your computer fails to boot. These two codes are audio and visual cues that help determine any hardware issues that could be keeping your PC from turning on or booting.
POST codes usually indicate the point at which the system encountered a hardware issue during the booting process. This way, you can identify the source of the problem. For example, if the POST code indicates an error with memory initialization, it would mean that you need to troubleshoot your RAM.
Beep codes are the audio cues in the form of a series of beeps that you hear when a computer powers up. For example, three beeps may indicate no video card detected so you may want to reseat your GPU to resolve the problem.
While POST and Beep codes may be useful, each manufacturer uses different code systems on their motherboards. You can identify the issue your computer is experiencing by searching online for the codes your motherboard manufacturer uses, or by checking the motherboard documentation.
8. BIOS/UEFI Updates
If there’s no POST code, check whether your motherboard’s BIOS is current. You can update the BIOS/UEFI even if your computer fails to POST. Consult your motherboard manufacturer’s documentation or do an online search to check for the most recent BIOS version for your computer’s system.
9. Reseat Connections Within the PC
If you recently worked inside of your computer or it was recently transported somewhere, there’s a chance one of its components has come loose within the case.
You can reseat everything by opening your computer, removing the side panel and checking that the various connections inside it are properly seated. Reseating reestablishes these connections and usually fixes the Windows 10 won’t boot issue.
Check that all components including the RAM, GPU, and motherboard cables are seated in their respective sockets. You can do this by removing each of the components and plugging them back in.
If there’s a faulty RAM stick or faulty GPU, try booting without them and see if your computer turns on.
10. Test Your Drive on a Different PC
If you don’t have a backup of your hard drive, take it out, connect it to a USB adapter or dock, and plug into a different working computer. If the hard drive is still working, chances are you’ll be able to copy your files onto an external drive before reinstalling Windows 10 or taking your PC for repair.
Other Things to Try When Windows 10 Won’t Boot
- Check for any signs of electrical shorts within the PC as these can cause your computer not to boot at all, or damage it.
- Test your power supply and replace it immediately if it fails or doesn’t function properly. The power supply unit tends to cause components inside the computer to work selectively or intermittently.
- Boot with essential hardware and check whether the computer starts normally or not. Reinstall each piece of hardware at a time and use a Power On Self Test card to test the computer and identify the component that’s causing your computer to not come on completely.
- Once you identify the faulty hardware, replace it immediately.
If all else fails, seek expert advice and assistance from a reputable computer repair service, or contact your computer manufacturer’s tech support team.
