The host is normal, the monitor can t be turned on, and the computer host can be turned on, but what

Generally speaking, it is the reason for the interface, and the landlord looks at the interface at both ends. If there is no problem with the interface, it may be a problem with the data cable. If the data cable is fine, then turn on the host to see if there is anything abnormal in the interface between the motherboard and the graphics card. In short, it is a step-by-step investigation.

That's a problem with your graphics card, which means that the console doesn't turn on, and you tell me your details.

How do you know that the host is normal, the fan rotation is not necessarily normal, press the numlock key of the keypad when you turn it on to see if it flashes, flash normally look at your host The interface of the monitor generally does not have problems The host is normal and the display does not display Then look at your graphics card If it doesn't work, just look at the monitor.

Looking at your description, it shows that your host is very abnormal. In general, the lack of synchronization signal on the display is caused by a problem with the main unit. It appears that the graphics card is loose due to your repeated unplugging of the VGA connector.

It is recommended to open the case and reseat the graphics card.

Generally, if the host starts normally, the keyboard will be detected by coms, and the three lights on the keyboard will flash at the same time, and then you will hear a "tick" sound, which means that the host starts normally! If you have any of these phenomena, then you have to troubleshoot the problem step by step, first check whether there is a problem with the display, and then check whether there is a problem with the graphics card.

There may be 3 aspects to judge:

1.Graphics card issues.

Replug it in, clean the gold finger, and see if the fan is normal.

If it doesn't work again, it will be replaced free of charge during the warranty period).

2.Cable problem (replugging, checking VGA or DVI interface) 3Display issues (Check if the electrical outlet is powered on.) If it's convenient, connect it to other computers to see if it's normal).

It's generally a plug problem.

There are many reasons why the computer host can be turned on, but the monitor can't be turned on, one is the driver of the graphics card, or some monitor failures, what are the reasons for this?

Power off, open the case, clean up the dust, especially the dust from the CPU fan, and check if the CPU fan is rotating normally.

Is the monitor power indicator on? If it doesn't light up, it may be a power failure of the monitor or a faulty power cable; If it is on, it may be a faulty display cable or a faulty display display.

One way that definitely works is to buy a new computer.

You plug and unplug the memory module to see if it can be restored, and remember not to check the power supply to see if the power supply is plugged in tightly.

It may be that the socket is loose, reseat the wiring parts to see if there is any change?

Good luck!

As the core component of the computer, the computer host often faces various problems, one of which is the sudden failure to turn on. This situation can not only be distressing, but can also have a detrimental effect on work and school. So, why can't the computer host turn on all of a sudden?

Next, I will answer this question from a number of aspects.

First, the power supply problem.

The power supply is one of the core components of the computer's main computer, and if there is a problem with the power supply, the computer will not work properly. There are several scenarios that can cause a power failure:

1.Loose or damaged power cord: Check that the power cord is plugged in, and if it is, you can try replacing the power cord.

2.Power overload: If the computer's host computer is overloaded, the power supply may not work properly. You can try unplugging some unnecessary equipment to reduce the load.

3.Power Aging: The power supply also has a lifespan, and if the power supply is aged, it may cause the computer to not work properly. Consider replacing the power supply.

Second, hardware problems.

Hardware problems are also an important reason why the computer host does not work properly, and the following situations can lead to hardware failure:

1.Memory module corruption: The memory module is an important part of the computer's main computer, if the memory module is damaged, the computer will not boot properly. You can try replacing the memory module.

2.Hard disk failure: The hard disk is an important device for storing data, and if the hard disk fails, the computer will not boot normally. You can try replacing the hard drive.

3.Motherboard failure: The motherboard is one of the core components of the computer, and if the motherboard fails, the computer will not boot properly. You can try replacing the motherboard.

3. Software problems.

Software issues can also cause your computer to fail to boot properly, and there are several things that can cause software malfunction:

1.Operating system failure: The operating system is the core software of the computer, and if the operating system fails, the computer will not boot normally. You can try to repair it using an operating system installation disk.

2.Virus infection: Viruses can damage your computer's software system, causing your computer to not boot properly. You can try using antivirus software to scan and remove viruses.

Fourth, other issues.

In addition to the above scenarios, there are some other issues that can also cause your computer to not boot properly, such as:

1.Graphics card failure: The graphics card is one of the important parts of the computer, and if the graphics card fails, it may cause the computer to fail to boot properly. You can try changing your graphics card.

Fault: The CPU is one of the important parts of the computer, and if the CPU fails, it will also cause the computer to fail to boot properly. You can try replacing the CPU.

3.Fan failure: There are multiple fans inside the computer, and if the fan fails, it may cause the computer to not boot properly. You can try replacing the fan.

In the process of daily use of the computer, if the computer host suddenly fails to start, it may be caused by various reasons such as power supply, hardware, software, etc. When dealing with such problems, we need to eliminate all possibilities one by one, and finally find the root cause of the problem, so that we can take appropriate measures to fix it. If you can't solve it yourself, you can also consider seeking professional help.

When the computer console suddenly fails to turn on but the display is normal, there may be one of the following reasons:

1.Power supply issues: It could be a power supply** that is faulty. Check that the power cord is securely connected and make sure the plug is properly connected to the power outlet. You can also try replacing the power cord or connecting to a different power outlet to see if the problem is resolved.

2.Switching issues: The console's power switch may be damaged or malfunctioning. Check that the switch is working and try a different method, such as pressing the power button directly or using a remote control, to start your PC.

3.Hardware failure: Hardware components inside the host computer can fail, such as the motherboard, processor, memory, or hard drive.

This can cause your computer to not start up properly. Inspect for any visible physical damage or burn marks. If possible, try reinstalling or replacing the faulty component.

4.Overheating: If the internal temperature of the computer is too high, the overheating protection mechanism may be triggered, causing the computer to fail to boot.

Check that your computer's main computer's radiators and fans are clean to make sure they're working properly. Remove any dust or debris that may be clogging the radiator.

5.Software issues: Sometimes, the computer won't boot due to an operating system or software issue.

Try a cold start, which is to disconnect the power supply and wait a long time before reconnecting the power supply. If the problem persists, you may need to use a repair tool or reinstall the operating system to fix it.

Summary: Reasons why your computer won't turn on can include power issues, switch issues, hardware failures, overheating issues, and software issues. By checking the power connection, switch status, hardware damage, heat sink condition, and attempting a cold start, you can gradually rule out possible causes and resolve the issue.

If the problem persists, you may need to seek professional technical support.
