The computer plays with a black screen, and the computer plays with a black screen

First, understand what was going on and what you were doing before the failure. If the computer fails after overclocking the CPU or memory, etc., the fault is related to overclocking, as long as the frequency is restored to normal.

2) If the computer is opened abnormally when the optical drive is being read and the computer fails, the fault is caused by misoperation, and this fault is generally put back into the optical drive, and then close the optical drive tray.

3) If the computer fails when a device is plugged and unplugged with power, the fault is related to the plugging and unplugging device, and it can be recovered by restarting the computer.

4) If the computer fails when using a certain application software, the fault may be caused by this program software, and the program software can be uninstalled and reinstalled to eliminate the fault; If it doesn't work, it may be that there is a bug in the program software itself and it cannot be used.

If the computer fails after entering the system, there may be many reasons for the failure, and it needs to be eliminated step by step. First, use Tencent PC Manager antivirus software to check and kill viruses, and clean it thoroughly. Troubleshoot failures caused by viruses, and if troubleshooting, it is failures caused by viruses.

Specifically, it is a problem with the **cable or the display,You can first check whether the two ends of the power cord of the monitor are loose,Then check whether the two ends of the **wire** are loose,If it is not a contact problem,Then you need to have another monitor and**cable to replace and exclude confirmation。

Graphics drives life.

Both of these will do.

Installing the graphics driver will solve the problem.

Black screen issue:

Hope it helps:

There are many reasons why a computer has a black screen, and the common ones are:

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor graphics card contact or;

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

Machine infection. CIH virus, BIOS

is destructively refreshed.

Microsoft black screen, please patch.

Most of these problems are the relationship between the memory and the graphics card, loose or poor contact, just move it or use the eraser to wipe the gold finger of the interface

Look at the software first, then the hardware. The software is simply reinstalled from the graphics card driver, try not to install the latest version, and the new one may not be good. Then there are other drives.

No, find someone who understands to redo the system, install the driver, especially the graphics card driver. The hardware issue could be that the memory is fake, or the motherboard and other hardware are not compatible. This will also happen when two memories are plugged in at the same time, so try pulling one out.

Look at whether the power supply is enough, the current power supply is less than 300W is basically not enough.

The causes of a black screen failure are generally caused by the following parts: the display itself is faulty, the graphics card is damaged, the host power supply is faulty, the motherboard or CPU is faulty, etc. Judging from the fault phenomenon, the display indicator flashes normally and there is a grating, which can be judged that the display is good.

After the host is turned on, the CPU fan rotates normally and the hard disk can boot normally, which indicates that the possibility of the host power supply failure is very small. In terms of CPU, the quality of the Athlon CPU is very good and there is no overclocking, so it really shouldn't be damaged, and judging from the fact that there is no prompt sound after booting, it will not be a problem with the graphics card and memory, because if there is a problem with these two parts, the machine will definitely make a horn sound of different lengths. Finally, the potential for failure is concentrated on the motherboard.

I suddenly remembered that the CMOS was not properly modified in the past, which was beyond the scope of the motherboard's tolerance, which led to a similar motherboard's self-protective black screen failure, and then the CMOS was cleared and the default value was restored. Could it be that the CMOS settings have been changed due to a virus or other reasons?

Regardless of whether it is or not, try it with this method first, first disconnect the power supply and open the chassis, and then find the position to clear the CMOS jumper, because you can't find the jumper for a while, you can find one on the motherboard, but you must remember the location, use the jumper to clear the CMOS jumper shorted for a few seconds, and then take off the jumper and put it back in its original position. Next, turn on the power and turn on the host, and find that the fault has not changed in the slightest, it seems that this time it was in vain.

Could it be that the motherboard components are burned? That's miserable, because the maintenance of the motherboard is very difficult, most of them have to be replaced, put the host with the cover removed under the light and observe carefully, hoping to find the problem, suddenly saw that the connection part of the memory module and the socket near the CPU fan has a thick layer of dust, so I forcefully pressed down the pressure on both ends of the memory module, removed the memory module, found a brush and a blow balloon, cleaned the dust on the memory slot and memory module, and blew it completely with a blowing balloon, and plugged the memory module back in, Connect all parts and turn on the power, press the start switch, only listen to the sound of "drop", and the screen finally reappears in English self-test prompts, and enter the system normally. So far, the fault has finally been successfully eliminated.

Afterwards, the cause of this failure was mainly due to the airflow generated by the high-speed rotation of the CPU fan to drive a lot of dust, constantly blowing to the memory modules and slots close to it, and the memory modules and slots have many contact points and small gaps, resulting in a large amount of dust retention, over time, the dust accumulates thicker and thicker, and the effect of moisture causes a short circuit between the memory module and the plugging contacts. In order to avoid such failures, you should develop a good habit of cleaning all parts of your computer regularly.

The first is.

Copy, the memory and graphics card are oxidized bai, resulting in poor contact with the memory slot or graphics card socket du, resulting in black.

zhi screen, it appears.

The possibility of a black screen accounts for 80%, and the solution is to turn off the power, turn on the compartment, dial out the memory, and the graphics card, align the memory and the gold finger of the graphics card (that is, where there is a copper sheet) and wipe it back and forth with an eraser at least 6 times, blow the ash, and then plug it back, and the boot is generally OK.

The second is the problem of power supply, when the filter capacitor of the power supply bulges and leaks, when the power supply is insufficient after starting, it will cause the power supply to start self-protection, power failure, no electricity, and naturally a black screen.

The third is,There is a problem with the connection cable between the host and the display,Unable to transmit data,Naturally, the screen will be black。

Fourth, it is a virus in the computer, there is a problem with the operating system, and there will be a black screen.

Open the case, dial out the graphics card, and plug it back in. Then reinstall the graphics driver. It's usually a display problem, but of course there are other reasons, which is hard to say. Let's try this first. Probably this reason is the simplest.

There is also a check if your CPU fan is normal.

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine.

If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Change to a normal CPU (should be compatible with the tested computer), boot the computer and re-test, if the black screen still appears, you can only change to a motherboard, and the problem should also appear on the motherboard.

There are generally four cases of computer black screen failure:

1. All black. The main unit and display (including the indicator light) are not lit.

2. Indicator light.

The indicator light of the monitor is on, but the indicator of the host unit is not.

3. The monitor does not display.

The indicators of the monitor and the main unit are both on, and the switching power cooling fan is also rotating normally, but the display is not displayed.

4. Dynamic black screen.

Dynamic black screen, displayed when turned on, but not after a while.

How to solve the black screen of your computer:

1. Check whether the connection cable between the monitor and the computer is tightly installed;

2. Remove the computer memory module, wipe the gold finger with an eraser and put it back (poor contact will cause the computer to boot up with a black screen);

3. Replace the memory, graphics card, display, and cable to diagnose the fault.

4. If the system file is corrupted, use the U boot USB disk to reinstall the system.

The first thing to see if there is a problem with the monitor.

Check the fan if not.

Let's take a look at the memory.

Reinstall the system without any problem.

Dude,It may be poisoned.,If you can't kill it.,It may also be that you accidentally deleted a file on the C drive.,It is recommended to reinstall the system,

Generally, there are two possibilities that cause a black screen, the graphics card and the monitor, and it is best to find a monitor and try it.

It is recommended to check the memory module and hard disk, and check whether the heatsink is normal.

If there is a problem with the hardware, you need to take it to a repair shop to take it to a repair shop.

Poisoning, the next 360 use to see.

Let's take a look at the switch on the monitor.

Take out the graphics card and wipe the gold finger with an eraser.

Let's try reinstalling the system.

The best way to do first aid is to reinstall the system, and if you can't reinstall it, you have to send it for repair.

Analyze possible causes of failure:

The situation is generally divided into two kinds One is caused by software, that is, the driver is not right, and the problem will be solved naturally if you try to light up the driver of another version, and the other is caused by hardware, and it is best to replace it with the same model of graphics card to test it.

In the absence of a malfunction of the graphics card, there are several scenarios that can lead to a black screen:

1. The graphics card itself does not support this game, change the graphics card.

2. The graphics driver does not support this game, upgrade the graphics driver and replace it with a new driver.

3. The refresh rate should not be set too high, not more than 70Hz.

4. Plug and unplug the graphics card and memory, and polish the gold finger of the graphics card and memory.

Extended Information: How to restart a black screen when playing a game on your computer:

1. Right-click "My Computer" and select "Properties". , and then select the "Advanced System Settings" item in the open system properties window. Then open the "System Properties" window, switch to the "Advanced" selection card, and click the "System and Recovery Settings" button.

Then uncheck the "Auto Restart Startup" item in the window that opens and press confirm.

2. When the computer produces a blue screen in the process of use, we can enter the "System Log" manager to view the root cause of the system failure. Open the Run dialog box and enter the command to view the log information and locate the cause of the system failure.

3. We can also try to fix the system by disabling some boot items. Open the Run dialog box, enter the command msconfig to enter the System Configuration Utility interface, and select the Diagnostic Startup option under the General tab.

4. There is also a way to fix the computer blue screen or reboot failure, which is to press "F8" to enter the system failure menu when the computer starts, and select the "Safe Mode" entry or "Last Correct Configuration" item to enter the system, which will and may repair the system.

It may be that the power is off, resulting in a black screen of the computer, or there is a problem with the computer itself, it is possible that the computer is stuck, it is recommended that you go to the relevant store to repair it, I hope you can adopt it, thank you.

The black screen can be explained by the software and hardware of the computer. On the hardware side, overclocking is a major cause of blue screen on your computer. That is to say, the computer is overloaded with calculations, resulting in too many internal calculations, which overheats the CPU and leads to system errors.

Replace a powerful fan and take good measures to cool your computer.

The display has not been reflected after you restart,Is there a reflection of the chassis?,If there is a reflection, it should be a matter of memory、Graphics card,If the display is normal,You can see the motherboard screen,It's suddenly off,It may be that the CPU temperature is too high,It's time to find a software to measure the hardware temperature while the machine can be opened,You can rule out whether it's the CPU temperature,If it's more than 80 degrees,The temperature is too high.,It's easy to go off。 Normal should be about degrees.
