What should I do if the normal display of the host computer does not display?

When you install the system, is it out of reach, or can you get on, but after restarting, it prompts something 321 The graphics card is not plugged in properly, and the graphics card is reinserted after shutting down.

2 If the memory is not plugged in, turn it off after shutting down.

If it doesn't work, unplug the memory and wipe the gold finger with an eraser, and the same problem is the case with your machine.

The reason was that the hardware was loosened when the machine was moved into him.

In fact, just dial the memory or graphics card.

Whether you connected your friend's monitor to your console or your monitor to your friend's console, I don't understand how you changed it.

If your console is connected to your friend's monitor and then changed back to your own computer and can't be displayed, it is likely that the display resolution is wrong.

F8 enters safe mode and modifies the resolution.

Broken graphics card? Or maybe it's too dirty? Perhaps, the cause of this problem has to be taken apart and examined.

I used to display when the graphics card was bad and couldn't get into the system, but it was already in the system. Naturally, it is useless to reinstall the system.

Excluding hardware reasons, it may be that the resolution is turned up, and the power is turned on without stopping F8, and the safety mode can be lowered.

First of all, make sure that there is no normal boot, in fact, reinstall the graphics card driver to see, if not, the VGA port is not in good contact, change the memory to another card slot (it is best to unplug the motherboard power).

What color is the light of the monitor.

You can try Ctrl+Alt+F7 to force the resolution down and see.

Summary. Hello, let me first say a few points for you to judge, the specific problem you can describe.

1. First of all, determine whether the wiring board turns on the switch, whether the monitor turns on the switch, and whether the computer host turns on the switch.

2. Under the premise that all switches are turned on, can the computer host be turned on normally? For example, does the computer host have an alarm sound, and does the power indicator display normal? If it is not turned on properly, the monitor will not be displayed, although the host is working, but it is not turned on.

3. Whether the display cable is connected to the integrated graphics card, the computer with an independent graphics card will not be displayed when connected to the integrated graphics card.

4, whether the display is black or has English letters, there are English letters need to look at the English description specifically, I will help you judge the problem, no display does not rule out the possibility of damage to the display itself.

I hope mine can help you and look forward to getting your likes, thank you.

What should I do if the host is connected to the monitor normally, but the monitor is not displayed.

Hello, can you describe the situation in detail? For example, can the host computer boot up normally?

As the problem is described, it is indeed a problem with the display, and now you need to look at two situations to judge the problem, 1 is the display indicator after the black screen, green or yellow and red? 2 is the screen after the screen is black, can you see the faint characters when you look at the screen from the side? If the indicator light is black, there is a problem with the power strip, if it is a green light, and the screen can see faint characters, there is a problem with the high voltage board.

The maintenance cost of these two kinds of faults is not high, and it can be solved for dozens of dollars.

Situation 1: The computer host is switched on and off normally, and the monitor is not displayed.

1. Observe the keyboard indicator, if the indicator can be displayed normally, you can confirm that the computer can start normally.

3. If it is normal, then see if the display switch is turned on, if it is turned on or there is no response, you should consider that there is a problem with the display hardware, try to change the monitor.

2. It may also be a problem with the graphics card driver, just update the graphics card driver in safe mode.

First rule out the poor wiring contact. Then unplug the memory module and use the eraser to use the gold finger. Clean the dust inside the case. If it is 2 RAM, try one first.

Check if the power light of the monitor is on, if there is no problem with the power supply. Disconnect the data connection of the host computer again, and if there is any display on the display, if there is a problem with the graphics card of the host computer.

Make sure that the power supply of the monitor is connected and that the connection between the monitor and the host unit is not loose.

First of all, the monitor should also be turned on;

If the monitor is turned on and it is still not displayed, see if the cable is loose, if it is loose, plug it in tightly;

If it is not loose, it still does not display, maybe it is a problem with the graphics card and motherboard, and you need to open the case for inspection.

Press the Ctrl, Alt, and F7 keys on the keyboard at the same time. Just see if it's good. You try.

Addendum: If it doesn't work, it doesn't necessarily mean that the display is broken, but the graphics card may be bigger. Open the case, clean the slot, polish the gold finger of the graphics card, and at the same time see if there is a capacitor bulge on the graphics card, and if there is, solder it.

The display has a color bar moving when the host is not turned on, which means that the display itself is detected normally, which is good.

After the host is turned on, the display screen is black and there is no image, which means that the signal has come, but it cannot be displayed normally.

You can unplug the cable of the monitor and check it to see if the pins in the two connectors are bent and deformed, and sometimes just plug it back in.

If it doesn't work, you have to open the main chassis and remove the graphics card to check.

There is also the possibility that there is more than one graphics card installed on the console. You see if there are two graphics card ports on the console, and if so, you can unplug the display cable and plug it into the other port.

When you need to use another graphics card, you need to set up the graphics card in CMOS, and then change the display cable to another interface, and you're good to go.

The steps to solve the problem are as follows:

1. The system power management is set to automatically turn off the display.

Solution: Some computers may have set up a power management plan, the monitor will automatically turn off after not operating the computer for a short time, then you can try to slide the mouse or tap the keyboard to re-wake the monitor, and the computer will return to normal after the screen lights up. If you have a stable power supply, consider changing the display auto-off mode to never.

2. There is a problem with the connection of the monitor or signal cable.

Solution: If you press the switch and can hear the sound of the system starting, or the squeak noise of the disk reading, it means that the computer has been started, but the display is still pitch black after a long time, which means that the computer display is broken, or the signal cable is loose, then you need to see if the indicator light of the display is on and whether the signal cable is plugged in.

3. The memory module is incompatible or the gold finger is oxidized or the contact is poor.

Solution: For memory failure, we can make a rough judgment by the sound of the motherboard alarm, if the motherboard is powered on, it emits a tick....Tick....The continuous interval of long sounds, one long and three short, or one long and one short (varies from BIOS to BIOS), can be judged as a memory error. The most common problems with memory are incompatibility and poor contact, if it is incompatible, you need to unplug one of them, and if it is poor, you need to properly clean the inside of the chassis.

Hello, is it the brightness of the web page, or the computer screen is not bright.

Questions. Yes.

It should be relatively low in brightness.

Did you adjust the brightness?

Questions. If the power goes out, the display will not light up if the call comes back on.

Is it a black screen or low brightness?

Questions. No.

Black screen. Oh oh oh, that's it.

Wait a minute. Turn off the computer normally and start it back after a while.

Desktop computers, right.

Questions. That's right.

Uh-huh. Questions.

Do you want to force a shutdown?

After shutting down, unplug the computer.

Right. Force shutdown.

Try again later.

Remember to replace the display switch as well.

Possible causes:1If there's a problem with the monitor, it's broken.

2.There is a problem with the cable connecting the monitor and computer.

3.Memory module problem, memory module bad contact.

4.Motherboard electrostatic reaction.

5.There is a problem with the motherboard.

Solution: First of all, see if the monitor is broken, you can power on separately to see if the monitor is normal.

If it's broken, you can try a different monitor.

Cable Problems and Solutions:

First of all, check whether there is a problem with the connecting cable, whether the connection is loose, or whether the connection cable is not in good contact.

Just update the cable.

Memory module problems and solutions:

The problem of memory modules is generally that the memory modules are dirty, resulting in poor contact. The general problem arises with Goldfinger.

The easy way to do this is to wipe it with an eraser.

Motherboard electrostatic reaction solution:

Motherboard problems and solutions:

For the problems of the motherboard, professionals need to test it, and do not disassemble it without permission, otherwise you will bear the consequences.

Generally speaking, if you press the main chassis, the screen does not reflect at all, you check whether the plug is loose to connect the VGA and the graphics card! 1.Check if the line is normal2

If it's an integrated graphics card, then you don't have to look at 3If it's a discrete graphics card, just remove the graphics card and snap the gold finger! I put it on 4

It may be a memory problem, a memory problem, and it is possible that the screen will be black! Follow these to see if it's a motherboard issue. You turn on the speaker to see if you can get the sound of the computer interface, if it can be turned on normally, it means that the memory and the motherboard are fine, the problem is that the graphics card is best, if you move the parameter settings in the BIOS, it will also cause the screen not to be displayed, at this time you have to discharge, remove the battery, and then put it on, and the BIOS will restore the production settings.

But this is after your VGA is plugged into the integrated graphics card, and some motherboards will be automatically recognized!

1. Check whether the connection of the monitor is normal, if the wiring is loose, please plug the wiring firmly and plug it in.

2. If the monitor connection is normal, move the host to the neighbor's house and try to borrow the neighbor's monitor to turn on to verify whether it can be displayed normally. If you can, it means that there is a problem with your home monitor. If it doesn't, there is a problem with the computer interface or motherboard.

3. If it can be displayed normally, take the monitor to the repair shop for repair. Maintenance** generally looks like around 100-150. The main problem is usually a damaged high-voltage bag or a lamp problem.

4. If it can't be displayed normally, take the host to the repair shop for maintenance, and determine the maintenance according to the specific problem.

1. The monitor is not powered on.

2. The signal cable of the display is not connected.

3. There are two display interfaces on the host, and the interfaces are not connected, such as the motherboard with integrated graphics card, and an independent graphics card is added, and the display signal cable is connected to the integrated graphics card when wiring.

4. The computer host is not fully started, but only powered on.

There's a problem with your monitor's driver, and you say "beep" a few times after turning it on. beep", and then I heard a "beep" sound, this is the graphics card is not plugged in, you can check it and plug it in again, about the display first green and then yellow, this is a problem with the display picture tube.

The monitor is not compatible with the motherboard of the host, and my previous computer was like this, and the staff told me this when I took it to the computer city.

Check to see if the monitor switch is turned on, or it may be that the power cord of the monitor is loose, unplug it and plug it back in.

The graphics card's cable is not connected to ......The display power supply is in poor contact......

If the light on the monitor is on, the VJA cable behind the monitor is not connected.

If there is only one computer to judge the failure of the computer power supply or motherboard, try to change the power supply, if it does not work, it is the motherboard.

There are two sockets on the back of the main unit, which may be plugged in by mistake. That's the question for me.

If you don't turn on the monitor, or the wiring on the monitor is loose, you can take it to the repair point to take a look.

Here's why:

1.The cable is broken;

2.poor contact;

3.The monitor doesn't turn on, or there's no power coming in (you can tell if the light on that monitor is flashing);

4.The graphics card hangs up;

6.The display is tuned to full black, and of course it is not visible;

Aside from the fact that the monitor is broken, there are three main points about this:

1. There is a problem with the contact between the connection line between the host and the display;

2. The motherboard is broken and needs to be bridged, and general maintenance points can be done;

3. If you have problems with the graphics card or memory driver, you can remove the memory module and wipe the metal part of the memory module with an eraser;
