After the computer has been running for a while, the host is still running, and the monitor has no s

1. Test the display separately Method: In the case of shutdown, turn on the power button of the monitor separately to see if the display has a similar "no signal" prompt, if there is good, if there is not, there may be a problem with the display.

3. The host hardware is faulty, which may be the motherboard or power supply.

Check them one by one and send the follow-up results for review.

If the CPU temperature is high, recoat the thermal grease, and replace the heat sink if it can't.

The case is dusted, and the gold fingers of the memory and graphics card are polished with eraser.

If it is not solved, send it for repair, there may be a problem with the graphics card or monitor.

Try the monitor on a different console if it's in good condition. It's a graphics card problem, and vice versa. Personally, I think the most likely is that the connection between the monitor and the graphics card is poorly connected.

You open the computer case.

Take out the memory module.

Wipe it with a towel and wipe the slot again.

After that, plug in the memory and it's OK.

Suggestion: Try a different version of the system, if there is still a problem, check the hardware such as graphics card, hard disk, monitor, cable (you can move the computer, change the location), this situation is generally not a memory problem.

Hope it helps!

It feels like the sleep function is turned on!! It's very similar to yours, look at the power management to see if it's turned on, and turn it off when it's on.

It's simple, the display isn't plugged in.

It is recommended that you change the system disk and reinstall it

Only the installed driver can be recognized

The computer is turned on for a period of time, and the monitor has no signal, and the host is running for what reason.

It may be a virus, if not, it is a hardware problem, it is recommended to use the elimination method to try which hardware is the problem!

It could be a memory issue.

Find a genuine system disk to reinstall the system, and by the way, check whether the links of each line are strong.

The monitor has no signal but the computer keeps running, and here's how to fix it

Display wiring error is a problem often encountered by users, generally this kind of host has installed a separate graphics card, and many users have inserted the ** line of the display on the motherboard on the display interface, this is the wrong connection method, resulting in the computer can not be turned on normally, the display screen is black and there is no signal input. The user of the integrated graphics card must be correct when inserting the display interface of the motherboard, in addition, it is not excluded that the **cable is loose, or the display screen is black caused by the **wire damage.

Second, the computer memory is not plugged in tightly

Loose computer memory will also cause the problem that the computer cannot boot normally, which is a high chance, so it is recommended to try it first. We turn on the host computer, open the side panel of the chassis and pull out the memory module, and then reinstall the memory into the memory slot, if not, it is recommended to replace the memory into other memory slots, and then try to boot it to test.

If you have friends with multiple memory, you may wish to insert one memory first, and do not insert another memory first, try to boot the test, if not, change to another memory insertion, and this memory is not inserted, alternate test, it is not excluded that one memory is damaged, or one of the root memory is loose.

3. Motherboard button battery discharge test

The button battery is very easy to discharge, there will be a button battery on the motherboard, use a hand buckle or a driver to loosen the tenon of the button battery, then the CMOS battery on the motherboard will automatically pop up, then you can take it out directly by hand, place the button battery for ten seconds, and reinstall it in place, and test it at boot.

Recently, some netizens reported that the display screen is black.

No signal but the computer keeps running, what's going on? For this kind of computer boot, the host computer is running normally, but the monitor has no signal failure. The host is normal, the display has no signal is one of the more common faults in our daily use of computers, generally there may be the following reasons, you may wish to solve it through the following elimination methods.

Reasons and solutions for the black screen of the monitor and no signal but the computer keeps running.

The display screen is black and there is no signal, but the host is running the reasons and solutions.

1. The display data cable is not connected or loose.

If it is a newly installed computer, the first time it is turned on, the host is operating normally, but the monitor has no signal on the black screen, you first need to check whether the power of the monitor is turned on, whether the display is turned on, and you can look at the power indicator of the display.

DVI monitor data cable.

If the monitor is connected to the power and turned on, check whether the data cable between the monitor and the computer is connected normally and whether it is loose, and you can reconnect it again.

2. The display data cable is not correct.

Hard drive failure.

The main reason is that the hard disk is aging or due to improper use, which causes bad sectors and bad sectors, so that the machine is easy to crash when it is running. You can use special tools and software to troubleshoot, if the damage is serious, you can only replace the hard disk.

If the monitor is faulty, confirm whether the monitor is broken, turn on the power of the monitor, and see if it is abnormal. The possibility of damage to the computer cable between the monitor and the host computer is not low, but it is still necessary to check whether the connection cable is not in poor contact and replace it.

The computer screen shows that there is no signal, and the host is still running, which may be a display failure.

To put it simply, LED (largeelectronic display), the display screen is composed of several combinable display units (unit display board or unit display box) to form the screen body, plus a set of appropriate controller (main control board or control system) grinding cavity.

Therefore, a variety of specifications of display boards (or unit boxes) with different control technology controllers can be composed of many kinds of LED displays to meet the needs of different environments and different display requirements.

How to choose a display screen:

Many friends will have a budget when buying a monitor, and after having a budget, they will buy a monitor according to the budget. The usual way to do this is to choose from a range of prices that fluctuate around the maximum budget.

Choose the most suitable display for your needs, don't just look at the budget, there are also very good monitors in the low-cost range, which can naturally meet the needs. So when you're on a budget, choose the most cost-effective monitor that meets your needs. <>

In this case, you can first check whether the pins of the monitor data cable are bent or broken, then reconnect the monitor to the host, and finally remove the computer memory module to remove the dust and plug it back into the computer for processing. If there is still no signal after the above three situations are checked, it is judged that the graphics card is faulty, and the burial needs to be repaired by professionals. The solution to the sudden lack of signal on the computer but the host is still running:

1. Check whether the pins of the display data cable have bent needles or broken needles, if so, it is recommended to replace a new data cable; 2. If the monitor data cable is normal, please check whether the connection between the monitor data cable and the host is loose or falling off, and please reconnect the cable. 3. Turn off the computer and turn off the power first, then take out the memory stick, and use the eraser to align the gold fingers on both sides of the memory stick and wipe it until the hail is bright and shining (pay attention not to touch the small original next to the gold finger when wiping). Use a brush or leather bag to clean the dust in the memory card slot, and then insert the memory module back into the motherboard (if you don't know how to disassemble the computer, it is recommended to contact the maintenance personnel to deal with it to avoid damaging the small parts next to it).

4. If there is still no signal after reinserting the memory module, please observe whether the indicator light of the numeric keypad of the computer can change, if the "num" light changes after pressing the [NUMLOCK] key, there is an abnormal fault of the graphics card, please contact the maintenance personnel for processing.
