Sometimes the black screen turns off while playing

Reason for automatic shutdown of the computer:

Poor heat dissipation, power failure, and motherboard failure may cause the computer to shut down automatically or restart repeatedly. (Reboot is an important feature: sometimes it shuts down, sometimes it restarts).

When the core components of the system are damaged, the running computer may automatically shut down. Kingsoft security experts are here to provide you with special killing tools and system repair tools, please click Fast**.

In the running software, there are some software with the option to shut down when the task is completed, and the user may not have noticed and turned these switches on. These software are more common, such as Thunderbolt, Express, anti-virus software, BT**, **** and so on. In the software settings, there is an action that automatically shuts down after completing a certain task.

But generally the default setting is off. The purpose is to automatically shut down the computer when a task is completed when a task is running a more time-consuming operation.

Other hardware reasons. The solution to the automatic shutdown of the computer:

First of all, check whether there is a problem with the hardware, focusing on the power supply of the motherboard, CPU fan, host power supply, and power socket.

Check if there are some applications that have enabled shutdown after the task is completed. This is evident from this. The feature is that before shutting down, there will always be a program that has been run, and a dialog box will generally pop up to remind you to shut down. Hope.

The high temperature of the internal hardware of the computer is also a relatively common cause of computer abnormalities.

2) The power supply of the computer is faulty, resulting in abnormal power supply, resulting in frequent failures, etc.

3) The installed software is not concurrent, if the computer starts to use well, a certain day after installing a certain software soon after frequent computer failures, this problem is mostly incompatible with the software.

5) Computer hardware problems, such as graphics cards, or hardware incompatibility.

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.

You see if the screen saver settings are still for a while and then the screen goes black.

Is the temperature high, now the weather is also hot, and the heat dissipation is relatively better when you drive.

1. The cache settings are unreasonable. The system is under-resourced.

2. Viruses or Trojans, when viruses and Trojans are running, maliciously use system resources or damage system files, causing damage to computer resources and system files. It can be scanned and killed.

3. Hardware overheating. When computer hardware uses electricity, it generates heat. Therefore, the heat dissipation of the computer is also very important.

If you don't pay attention to heat dissipation, it can cause the hardware product to burn out or burn out.

1. See if the plug is in good contact.

2. Check whether it is a display problem.

3. The game resolution and the monitor resolution are different, which will cause it to not work properly.

Obviously, you are a graphics card problem, it is likely that the graphics card temperature is too high or the CPU temperature is too high, the hardware is automatically protected, it stops working, your monitor can't receive a signal, from the fact that your host is still on, it should be that the graphics card temperature is too high, (the CPU temperature is too high, the system will be directly black), solution: open the side panel of the case, and then no, the fortune fan shines on the host to blow (to open the side panel of the case).
