Colored stripes appear on the right side of the computer screen

Analysis: Abnormal display of display colors may be caused by poor contact between memory or graphics card and cables, or poor heat dissipation.

Processing: Generally, it can be recovered by restarting, if it is invalid, the operation is as follows:

1.Shut down (if short press the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don't be weak).

The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.Enhance the heat dissipation inside the case and the environment in which it is used, and reduce the time spent playing large games in summer.

Hello friends:

The causes and treatment of streaks on desktop computers are as follows:

1) The first reason is that the slots of the graphics card and the motherboard are not fully contacted, resulting in the phenomenon of streaks, Jianyi: as long as the power is turned off, the chassis is opened, the graphics card is taken out, and the eraser is aimed at the gold finger to wipe it a few times, and then reinstall it back, sometimes deal with it like this, just start it from the new, if it is not good to deal with it in this way, which is the performance of the main chip of the graphics card declines, leading to the appearance of stripes on the display, Jianyi repairs the graphics card or replaces the graphics card.

2) The second reason, which is the problem of the LCD screen, generally occurs because: the filter capacitor at the output end of the power supply circuit is bulging and discharging, leakage, and the power supply of the drive board circuit is insufficient, the MCU core and the main chip appear virtual soldering, the screen line is in poor contact, and the main chip of the screen circuit is virtual soldering, insufficient power supply, or damage, and the horizontal or hard line is caused, and it may be that the power supply insurance of the LCD circuit is damaged, which will cause the white screen phenomenon. Solution:

Jianyi sent after-sales or LCD maintenance department to repair the display, of which the screen line is the most likely to have poor contact, 3) detection method: the judgment of this phenomenon is to borrow someone else's good monitor to try it, you can see the operating system, which means that there is a problem with the display, if you can't see the system, someone else's display is also a white screen, this is the problem of the graphics card, you can replace the graphics card.

Hope it helps you and I wish you happiness

In the case of color stripes on the display, we can first check whether it is caused by some graphics card drivers in the system, and for the frequent display screen blurring, it may be caused by computer hardware failure.

1. When the computer monitor has a pattern, we can first try to use the driver master to uninstall or upgrade the graphics card driver in the current computer to the latest version, so as to eliminate the blurred screen caused by the driver. 2. The graphics card is loosely connected or the graphics card itself is damp and other reasons cause the screen to blur when the display outputs the signal, in this case, we need to manually check the graphics card or clean up the graphics card dust to eliminate graphics card hardware problems.

3. The computer has color stripes caused by the hardware damage of the monitor, which is generally relatively high. Because among the many display problems, due to the quality of the display and the force area, etc., it may be damaged due to some collision reasons or the use of a long time, and this situation generally needs to be considered to replace the display.

The reasons and solutions for the display screen blurred screen given above are only the ones that appear frequently, and you also need to check your own computer. At the same time, we also need to pay attention to the computer cable used and the surrounding environment, whether there are magnetic fields and other reasons that affect the display, etc.

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

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.

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 safe mode of win95, and reset the display mode of the monitor.

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.

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.

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.

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

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

In 2019-

If this situation occurs in the computer, it is generally a problem with the computer hardware, and you can take it to the repair of the computer.
