The computer always has ripples and flashes, and the computer screen flashes horizontally?

Your computer configuration is not bad... The LCD sometimes shows water ripples one by one, from the bottom up. Sometimes the whole screen flickers, if the refresh rate, resolution are normal. The failure of reinstalling the graphics card driver and replacing the graphics card is still the same, and the water ripples still appear after replacing the display.

After testing, it was found that the culprit that caused the LCD screen to sometimes appear water ripples and sometimes flicker was actually "electricity". It may be that there is a problem with the quality of the power plug board, which causes the current to interfere with the LCD display, and the problem is solved after replacing a power supply plug board. Since then, the LCD has never had water ripples or flickering.

If your LCD monitor is flickering, water ripples constantly, and you have found a lot of online methods, and the parts that should be replaced have been replaced, and the problem is still not solved, you may wish to try the methods described in this article. Hope you can help you, thank you!!

Snowflake ripples, which are signal line interference.

If the signal cable of the computer is too inferior from the chassis, it is very likely to cause interference, it is recommended to buy a signal cable with a magnetic ring, which can reduce interference.

The interference is mainly caused by strong magnetic interference in the vicinity, the work of other electrical appliances, or the room is too small.

In the process of computer use,Streaks appear on the computer screenIt is an extremely common failure, there are many reasons, there are hardware reasons such as external force hitting the screen to damage the screen, this situation can only be sent for repair, but if it is caused by improper system settings, we can solve it by ourselves. In the text mode, the screen is characterized by confusion of characters, and in the graphic mode, it usually appears as a graphic layer, and horizontal stripes are produced due to internal or external interference.

1.Streaks on the computer screen: There are two main reasons for this:

1) External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;

2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2.Improper display resolution setting causes streaks on the computer screen: When the monitor is set incorrectly in the resolution of win95, the computer screen may be blurred when Windows is started, that is, the picture is layered, shaking, serious and even black screen of death.

Solution: Enter the setup or enter the security mode of win95, and reset the display mode of the display.

3.Conflict between the graphics card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and there is no response to random keystrokes, similar to a crash, processing method: enter modec080 at this time to be solved.

4.Poor heat dissipation effect of the main control chip of the graphics card: This will also cause streaks on the computer screen, and the treatment method is to improve the heat dissipation performance of the graphics card.

5.The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the computer screen will also be blurred.

6.Video memory corruption: When the video memory is damaged, there will be a blurred screen when the system boots up.

7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.

1. Streaks appear on the computer screen: there are two main reasons for this: 1) external interference:

If there is an electric spark or high-frequency electromagnetic interference near the use site of the monitor, this interference will cause the display screen of the monitor to produce white horizontal stripes. Solution: Avoid using the monitor in this situation; 2) Internal interference:

This interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it. 3) The service life of the display is too long: If the internal capacitor is too long, it will age and fail, resulting in too slow start-up, gray screen, and blurred font.

At this time, as long as the aging capacitor is replaced, the fault can generally be eliminated, but because it is also a very high-tech work, it is recommended to send it for repair. 4) Improper setting of display resolution: there may also be serious streak faults on the computer screen, this kind of fault will generally appear on older machines, if your computer is working under the Windows system, then you can press the F8 key to enter the security mode of the system, reset the display mode of the monitor, and generally be able to troubleshoot after restarting.

2. The solution to the flickering horizontal stripes on the computer screen 1. The computer screen is streaked due to improper display resolution setting: when the display is set incorrectly in the resolution of win95, the computer screen may be broken when starting Windows, that is, the picture is layered, shaking, serious and even black screen of death. Solution:

Enter the setup or enter the safe mode of win95, and reset the display mode of the monitor. 2. Conflict between the display card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and there will be no response to random keystrokes, similar to a crash, how to deal with it:

In this case, typing modec080 will solve the problem. 3. The main control chip of the graphics card has poor heat dissipation effect: this will also produce streaks on the computer screen

Improves the thermal performance of the graphics card. 4. The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the computer screen will also be blurred

Replace the memory with a higher speed, or slow down the speed of the console. 5. Video memory damage: When the video memory is damaged, there will be a phenomenon of blurred screen chaotic characters when the system starts

The memory strip must be replaced. 6. Virus causes: In some virus attacks, there will also be a flower screen, treatment method:

It can be eliminated by using antivirus software. The above is all the content of what to do if the computer screen flashes horizontal stripes, I hope the above content can help friends.
