The main unit is normal, the monitor has snowflakes and sometimes a black screen of 15

Reason why there are snowflakes on computer monitors:

1. Driver problems mostly occur after changing the driver version of the graphics card, or they may be caused by the driver file corruption. The solution is very simple, reinstall the driver that has passed the Microsoft WHQL certification, and there is no need to blindly seek new versions.

2. The heat dissipation effect of the main control chip of the graphics card is poor, not only because of the graphics card, but also because the temperature of the chipset of the processor, memory and even the motherboard is too high.

3. Video memory damage, when the video memory is damaged, there will be a phenomenon of blurred screen and confused characters when the system starts. Solution: The video memory chip must be replaced. Note that some video memory is integrated into the graphics card chip, so the graphics card chip must be replaced.

4. When the memory speed is too low, it will not match the speed of the host, and the screen will also appear.

5. The memory module problem may be caused by the damage of the memory module, you can remove the dust on the memory module by wiping, and then turn on the computer to see if the problem of the blurred screen is solved, if it cannot be solved, the memory module needs to be replaced.

There are two reasons why there are snowflakes on computer monitors

There are three scenarios:

1.Splash screen is a relatively common display failure, and most of the screen failures are caused by the graphics card itself. If you can occasionally enter the system or enter safe mode (F8), first reinstall the graphics card driver; Then it is to clean up the gold finger, which can generally be solved.

If the system can't get in, it is very likely that the video memory is damaged, and often when the system starts, there will be a blurred screen of confused characters, in which case the graphics card or video memory bar must be replaced.

2.If the temperature is too high, the fan of the graphics card is not good, or the air duct in the case is not good, resulting in too high temperature, and the temperature is high in summer, which is more common; Feel the temperature of the memory chip with your hand to check whether the fan of the graphics card is stopped. Then look at the AGP slot on the motherboard to see if there is any dust, check whether the gold finger of the graphics card is oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part.

3.The power of the power supply is insufficient. If there was nothing wrong with it before, this can basically be ruled out;

There are three reasons why there are snowflakes on computer monitors

First, the screen refresh rate is low: open the Display Properties panel, click Advanced, then select the Monitor tab and put it inside"Only the highest refresh rate supported by the display is displayed"Click the refresh rate marquee box next to it, and then click the refresh rate marquee box to select the highest frequency in it.

Second, electromagnetic interference display: is there any large electrical appliances next to it, or a speaker with poor demagnetization, the electromagnetic of such appliances will interfere with the display of the display. Just keep the monitor away from such electrical interference.

Third, display aging failure: If the above two methods cannot be solved, it may be display aging or failure, and it is best to send it for repair.

What is the fault of the computer snowflake screen?

1. First of all, it may be because the computer's graphics card has poor heat dissipation, which will lead to the failure of the computer's snowflake channel. 2. It may also be because there is a lot of dust on the fan of the graphics card, and if it is not cleaned up in time, it may lead to the failure of the computer snowflake screen. 3. When the gold finger of the computer graphics card is oxidized, if it is not wiped for a long time, it will cause the gold finger of the memory module to grow patina, and at this time, it will be in poor contact with the motherboard card slot, and the phenomenon of computer snowflake screen will occur.

Suggested workaround:

1. If it is because the heat dissipation of the computer graphics card is not good, you can remove the graphics card of the computer and clean up the dust on it, which can solve the fault of the computer snowflake screen.

2. When there is a lot of dust on the fan on the front card, it also needs to be cleaned regularly, so as to solve some problems.

3. After the gold finger of the graphics card of the computer is oxidized, be sure to remove the memory stick, and then wipe the gold finger of the memory stick with a rough eraser, and then insert it again, so that the applause of the computer snowflake screen is solved.

4. It is also possible that the hardware of the computer has failed, which is to contact professional maintenance personnel to replace the hardware, so as to fundamentally solve the fault of the snowflake screen of the computer.

Check the connecting line Kairu:First, check that the cable between the computer and the monitor is properly connected. If the connection is poor, it may cause snowflakes and a black screen. Try plugging the cable back in and making sure it's tight.

Replace the cable:If the cable is aged or damaged, it may need to be replaced with a new one.

Check the monitor power:Check that the monitor is powered on and connected. If the power is not turned on or the connection is poor, it may cause the monitor to go black.

Check your computer's graphics cardCheck that your computer's graphics card is working properly. If the graphics card is malfunctioning or over-staring, it can cause snowflakes and a black screen. Try reinstalling the graphics card driver or cleaning the heatsink.

Check your computer's memoryIf there is a problem with your computer's memory, it can cause snowflakes and a black screen. Try reinserting the memory with a new one or replacing it with a new one.

If the computer monitor snowflakes and then the screen goes black, it may be that there is a problem with the wiring of the monitor. You can try the following steps to solve this problem:

1.Make sure that the cable is securely connected. Disconnect the cable between the monitor and the computer, and then Kyuhin shouts to reconnect again.

2.If you are using a VGA cable, make sure that the pins on the plug are not bent or twisted.

3.Replace the data cable. If you're still having trouble after trying to reconnect, consider replacing the cable.

4.Try testing the monitor on another computer and see if the problem persists. If the same problem persists on another computer, then it is most likely a problem with the monitor itself and needs to contact after-sales service for further processing.

Please note: If the monitor is under warranty and the information provided by the manufacturer itself, it is recommended not to disassemble the monitor or replace the parts by yourself, so as not to affect the warranty.

There are three reasons why a computer monitor has a snowflake and then a black screen:

1. The internal problem of the display itself, it may be that the internal electric car components may be damaged or there is a problem with the display screen, please change the monitor and try it out, if it is broken, it will be repaired.

2. The graphics card asks the problem of dryness, if the integration fails, you can only spend money to buy a block and replug it in and then update the driver.

3. If the memory module is in poor contact or the gold finger is oxidized by the air, please remove and clean the dust, and then wipe it with an eraser and try it again to re-install it.

4. If it is a boot phenomenon, it may be that the disk has bad sectors or the system program is damaged, and it is recommended to send it for repair.

If you have a snowflake screen on your computer monitor, the first thing you need to understand is that this situation can involve a variety of issues, whether it is a hardware issue or a software issue. In the following article, we'll cover some of the methods you can try.

Method 1: Check the cables.

First, you'll need to check the cables to make sure they're installed correctly. If your monitor is connected to a computer, you need to check if the VGA or HDMI cables are loose or in bad contact, and if so, you need to connect them correctly and restart the computer.

Method 2: Replace the cable.

If there is no problem with your cable, then you can consider replacing the cable, sometimes the cable itself may have been damaged, causing the phenomenon of snowflake calendar.

Method 3: Change the resolution.

If the above methods still don't work, then you can try changing the resolution of your computer, because sometimes too high or too low resolution may also be one of the causes of the snowflake screen.

Method 4: Change the refresh rate.

Similar to changing the resolution, changing the refresh rate may also be able to solve the problem with the snowflake screen. You can change the refresh rate in your computer's settings, but generally speaking, a 60Hz refresh rate is good for most situations.

Method 5: Adjust the display parameters.

If none of the above methods can solve the problem, then you can try to adjust the parameters of the display, usually, you need to adjust the contrast, brightness and other parameters to the appropriate range to achieve a better display effect.

Method 6: Replace the monitor.

If you've tried all of the above and still can't fix the problem, then you may want to consider replacing your monitor. While it's rare, if your monitor is very old, it may have reached the end of its life.

Summary. The above are some of the solutions for the snowflake screen of computer monitors, different situations may need to consider different methods, it is best to understand the cause before trying to solve the problem, so that we can find the right solution faster. If you've tried these methods and still can't fix the problem, then you may need to seek professional help.
