修复显示器随机关闭和打开： (Fix Monitor randomly turns OFF and ON: )如果您遇到显示器随机关闭和自行打开的问题，那么您的计算机需要进行认真的故障排除才能指定此问题的原因。无论如何(Anyway)，用户还报告说，他们的显示器在使用 PC 时随机关闭，并且无论他们做什么，屏幕都不会打开。这个问题的主要问题是用户的 PC 仍在运行，但他们看不到屏幕上的内容，因为他们的显示器已关闭。
当计算机进入睡眠状态时，它通常会给您某种类型的警告，例如，PC 说它正在进入省电模式或没有输入信号，无论如何，如果您看到任何这些警告消息，那么您就是面对上述问题。有 5 个主要原因似乎导致此错误，它们是：
- GPU（图形处理单元）故障(Faulty GPU (Graphic Processing Unit))
- 不兼容或损坏的 GPU 驱动程序(Incompatible or corrupted GPU Drivers)
- PSU（电源单元）故障(Faulty PSU (Power Supply Unit))
- 过热(Overheating)
- 松散的电缆(Loose cable)
现在，为了解决问题并修复显示器随机关闭，您需要按照下面列出的步骤指导您如何修复显示器(Fix Monitor)随机关闭(OFF)和打开问题。因此，不要浪费任何时间，让我们看看如何解决上述导致显示器关闭问题的问题。
注意：(Note:) 确保(Make)您没有超频您的 PC，因为它也可能导致此问题。此外，请检查是否有可能导致此问题的BIOS中启用的显示器的省电或其他一些设置。
修复监视器(Fix Monitor)随机关闭(OFF)和打开
GPU（图形处理单元）故障(Faulty GPU (Graphic Processing Unit))
您的系统上安装的GPU可能有故障，因此检查此问题的一种方法是卸下专用显卡并让系统仅集成一个显卡，然后查看问题是否已解决。如果问题得到解决，那么您的GPU出现故障，您需要更换新的，但在此之前，您可以尝试清洁显卡并再次将其放入主板以查看它是否正常工作。
不兼容或损坏的 GPU 驱动程序(Incompatible or corrupted GPU Drivers)
显示器出现开机或关机、显示器休眠等问题大多是由于显卡驱动不兼容或过时造成的，所以要查看是否是这种情况，您需要下载并安装来自制造商网站的最新显卡驱动程序。如果您无法登录到 Windows，因为您的计算机屏幕在开机后立即关闭，那么您可以尝试将您的Windows启动到安全模式，看看您是否能够 修复监视器随机关闭和打开的问题。(Fix Monitor randomly turns OFF and ON issue.)
PSU（电源单元）故障(Faulty PSU (Power Supply Unit))
如果您与电源单元(Power Supply Unit)( PSU ) 的连接松动，则可能会导致显示器随机关闭和打开计算机上的问题，为了验证这一点，请打开您的 PC 并查看电源(Power)是否正确连接。确保(Make)PSU风扇正常工作，并确保清洁您的PSU ，(PSU)以确保其运行畅通无阻。
监控过热(Monitor Overheating)
显示器随机关闭的原因之一是显示器过热。如果您有一台旧显示器，那么过多的灰尘会堵塞显示器的通风口，这不会让热量逸出最终导致过热，这会关闭您的显示器，以防止损坏内部电路。
如果显示器过热，请拔下显示器并让它冷却几分钟，然后再次尝试使用它，解决此问题的最佳方法是用真空吸尘器清洁显示器通风口（设置低，否则可能会损坏您的显示器监控内部电路）。
随着显示器变旧，您会面临另一个问题，即老化的电容器也会失去正常充电的能力。因此，如果您面临频繁的显示器关闭和开启问题，那么这是因为显示器电路内的电容器无法将电荷保留足够长的时间以将其转移到其他组件。为了解决显示器(Fix Monitor)随机关闭(OFF)和打开的问题，您需要降低显示器亮度，这将消耗更少的电量，您至少可以使用您的计算机。
松散的电缆(Loose Cable)
有时，愚蠢的事情似乎会引起大问题，对于这个问题也可以这样说。因此，您应该寻找将显示器连接到 PC 的电缆，反之亦然，以寻找松动的连接，即使它没有松动，也要确保将其拔下，然后再将其正确插回。除此之外，还要确保您的图形卡正确就位，并检查与电源单元(Supply Unit)的连接。此外，请尝试使用另一根电缆，因为有时电缆也可能出现故障，最好验证这里不是这种情况。

Fix Monitor randomly turns OFF and ON
Fix Monitor randomly turns OFF and ON: If you are facing this issue where monitor randomly turns off and on by itself then your computer needs serious troubleshooting in order to specify the cause of this issue. Anyway, users are also reporting that their monitor turns off randomly while they were using their PC and the screen doesn’t turn on, no matter what they do. The main problem with this issue is that users PC is still running but they can’t see what’s on the screen because their monitor is turned off.
When the computer goes to sleep it generally give you some type of warning, for example, the PC says it’s going into power saving mode or there is no input signal, in any case, if you are seeing any of these warning messages then you are facing the above issue. There are 5 main cause which seems to cause this error which are:
- Faulty GPU (Graphic Processing Unit)
- Incompatible or corrupted GPU Drivers
- Faulty PSU (Power Supply Unit)
- Overheating
- Loose cable
Now in order to troubleshoot the issue and fix the monitor randoms shut off, you need to follow the below-listed steps which will guide you on how to Fix Monitor randomly turns OFF and ON issues. So without wasting any time let’s see how the above issues which lead to the monitor turn off problem can be fixed.
Note: Make sure you are not overclocking your PC as it can also cause this issue. Also, check if there is power saving or some other settings for the monitor that is enabled in BIOS which can cause this issue.
Fix Monitor randomly turns OFF and ON
Faulty GPU (Graphic Processing Unit)
Chances are the GPU installed on your system might be faulty, so one way to check this is to remove the dedicated graphic card and leave the system with only integrated one and see if the issue is resolved or not. If the issue is resolved then your GPU is faulty and you need to replace it with a new one but before that, you could try cleaning your graphic card and again place it in the motherboard to see it’s working or not.
Incompatible or corrupted GPU Drivers
Most of the issues in monitor regarding display turning on or off, or monitor going to sleep, etc are caused mostly because of incompatible or outdated drivers of graphic card, so in order to see if it’s the case here, you need to download and install the latest graphic card drivers from your manufacturer’s website. If you can’t login to Windows as your computer screen turn off instantaneously after power up then you could try booting your Windows into safe mode and see if you are able to Fix Monitor randomly turns OFF and ON issue.
Faulty PSU (Power Supply Unit)
If you have a loose connection to your Power Supply Unit (PSU) then it can cause monitor randomly turns off and on issues on your computer and in order to verify this open your PC and see if there is a proper connection to your Power supply. Make sure the PSU fans are working and also make sure to clean your PSU in order to ensure it runs unhindered without any problems.
Monitor Overheating
One of the reasons for monitor randomly turning off is because of monitor overheating. If you have an old monitor then the excessive dust build up blocks the vents of the monitor which doesn’t allow the heat to escape ultimately causing overheating which would turn off your monitor in order to prevent damage to the inside circuits.
If the monitor is overheating then unplug your monitor and let it cool down for few minutes then again try to use it, the best way to fix this issue would be clean your monitor vents with a vacuum cleaner (With low settings or you could damage your monitor inside circuits).
As the monitor gets old you face another issue which is the aging capacitors also loses its power to charge properly. So if you are facing frequent monitor turns off and on issues then this is because the capacitors inside the monitor circuits are not being able to retain the charge long enough to transfer it to the other components. In order to Fix Monitor randomly turns OFF and ON issue you need to decrease your monitor brightness which will draw less power and you would be at least able to use your computer.
Loose Cable
Sometimes the silly things seem to cause big problems and the same could be said about this issue. So you should look for the cable which connects the monitor to your PC and vice-versa to look for loose connection and even if it’s not loose make sure to unplug it & then again plug it back properly. In addition to this also make sure your graphic card is properly seated in its location and also check the connection to Power Supply Unit. Also, try another cable because sometimes cable can also be faulty and it’s best to verify that this is not the case here.
