Thousands of dollars is better than changing the computer, this kind of problem if you hear the system boot sound, the system enters normally, it means that the screen is a problem. This is also related to the motherboard chip.

It may be that the system refresh rate setting is wrong, you can check whether the display refresh rate setting is correct in your computer; It may also be that the driver of the graphics card is not installed correctly and you need to reinstall the driver; There may also be interference around your monitor or a malfunction of the monitor itself, try checking it using the rule of law. Here's a closer look:

1. Whether the display refresh rate is set correctly, check the method in the blank area of our computer desktop [right click] - [Properties] - [Settings] - [Advanced] - [Monitor] You can see that the refresh rate of the display is set, which is the reason why the monitor screen keeps shaking. Set the new frequency to the above, and then click OK to return to the desktop;

2. Check whether the graphics card driver is correct, sometimes when we enter the refresh rate of the computer's monitor, we find that there is no refresh rate to choose from, or the laptop cannot use keyboard shortcuts to adjust the brightness, all of which are caused by the graphics card driver is not installed correctly, you can enter the [Device Manager] to check whether there is a yellow exclamation mark next to the graphics card, or right-click to select Update Driver;

3. Whether there is interference around the computer, observe whether there is a strong electric field or strong magnetic field interference around the computer monitor, magnetic field interference is very easy to cause the computer screen to shake or flicker, the elimination method is to place the computer in another open place and then observe, you can also go to another place to take a good computer to test and eliminate, try not to close the display near large electrical products. You can also restart the computer monitor to see, generally the current display has an automatic degaussing function in the opening process;

4. Display hardware problems or power supply problems, you can use the elimination method to use other monitors to check whether it is the computer software or the display itself, among which the computer screen flickering encounters the most display power supply problems, and many are caused by the aging of the display;

The computer desktop icon keeps flashing, which may be a problem with the icon cache.

Because the icon's data is stored in the cache in the form of links, this can happen if the start and end positions of each element in the linked list change.

Encountering this glitch can be resolved by manually resetting the icon cache.

Here's how:

1. Right-click on the blank space of the desktop and select "Properties";

2. Switch to the "Appearance" tab;

3. Select "Icon" from the drop-down list in the "Project" box, change the size of the icon, and then change it back to the original setting.

There are a number of factors that can cause a flickering laptop. When the computer is running, the screen flickers or flashes irregularly, and sometimes horizontal and vertical lines appear. The splash screen and the snowflake screen are mainly caused by the problem of the graphics card,The snowflake screen is similar to the snowflake screen of the TV,The splash screen is like a problem with the graphics card driver,The picture is complete,But the eyes are extremely uncomfortable。

Therefore, the graphics card should be overhauled first, but problems with the display itself are not ruled out.

What's the deal with a splash screen on a laptop?

Splash screens and snowflake screens are mainly caused by graphics card problems, so let's take a look at three reasons for splash screens.

1. Splash screen caused by screen backlight.

Fault manifestation: The backlight of the notebook flashes from time to time, and the frequency is very fast, sometimes it flashes several times, sometimes it lasts for several minutes.

This situation is due to the instability of the high-voltage board that supplies power to the backlight of the screen or the ignition of the solder joint at the lamp joint is not firmly connected.

Fault performance: When the battery and power adapter are used at the same time, the laptop will flash from time to time, and the charging indicator in the lower right corner of the screen will be switched constantly, and the fault phenomenon will disappear when a single power supply is used.

This fault is mainly caused by the instability of the non-component of the battery switching circuit on the motherboard, and the fault can be repaired by repairing the components of the motherboard charging circuit. Don't be greedy to use dozens of dollars of power supply, this kind of power supply in the hand is fluttering, and the material used can be imagined.

3. Screen flickering caused by the defect of the screen itself.

The fault manifests itself as follows: Generally, there will be a bright line under the laptop screen at first, and after a short time, the bright line will evolve into a full-screen flash.

PS: The flicker screen fault indicates that the following delicate parts of the computer have been touched, and professional maintenance personnel need to deal with it, so as to avoid manual attempts.

Summary. Hello,Dear,Laptop splash screen is to change to a new machine,The splash screen of the laptop is basically caused by everyone adjusting the resolution of the computer too low,This we need to adjust the resolution of the laptop,This can directly right-click on the blank space of the computer desktop,Then select the display settings to directly adjust the resolution of the screen,This can adjust the resolution to the resolution recommended by the system,Or you can directly adjust it to the highest resolution。

Hello,Dear,Laptop splash screen is to change to a new machine,Laptop flashing screen situation is caused by the fact that the resolution of the computer is adjusted too low,This we need to adjust the resolution of the laptop,This can directly right-click on the blank space of the computer desktop to guess the rent,Then select the display settings to directly adjust the resolution of the screen,This can adjust the resolution to the resolution recommended by the system,Or you can also directly adjust the highest resolution。

Dear, there is another possibility, it is because the screen of the notebook is damaged, or it may be because the computer lacks a driver, you can use the driver wizard to detect the driver. The phenomenon of flickering screens in laptops may be due to three reasons. 1.

If your laptop has been in use for a very long time, the display is aging or has quality problems, which will cause the screen to flicker. 2.On the line connection of the laptop, there is a row of screen lines at the folded position, if the sedan car is not operated properly, it will support the breakage of the line, so that one of the lines affects the normal operation of the computer display.

3.The power supply of the motherboard screen of the laptop computer is not normal, which will also make the screen appear blurry or flash.

Dear, I'm very honored to answer for you: Laptop flashing screen Li Zhenghe does not need to change the machine, the screen failure is very clear and difficult to repair, it is recommended to replace the new screen. The full screen is full of color bars or hard lines, which is caused by the failure of the graphics card.

Extended information: Laptop, also known as "laptop", is a small and portable personal computer, usually weighing 1-3 kg. The current trend is to be smaller and lighter, but more powerful.

In order to reduce their size, notebook computers today use liquid crystal displays (also known as liquid crystal LCD screens). The main difference between a laptop and a PC is that it is easy to carry, and the motherboard, CPU requirements, memory, graphics card, hard disk capacity, etc. Although the body of the laptop is very lightweight, there is no doubt about its application, and the laptop is fully capable of daily operation and basic business, entertainment, and computing operations.

Today's laptops are differentiating different trends according to their uses, netbooks tend to be used for daily office and movies, business laptops tend to lack stable low power consumption to obtain longer battery life, home laptops have good performance and high cost performance, and game laptops are specially used in the cover hole to cater to a small number of people going out to travel and boring plays, enthusiast configuration, good entertainment experience, of course, not low, battery life is not ideal.

Can just changing the screen save it?

It's just that most of the flickering screens are screen failures, but changing the screen with wires may not necessarily be able to remedy it.

Do you still need to change the line?

If it's wired, it's mostly a problem with the graphics card.

This way. I forgot the password of Beijing Huizhitong entry platform.

There are two reasons: a problem with the graphics card driver, and the second one is a problem with the display output line.

It's a problem with the graphics card driver, you can update the graphics card driver to solve this problem, it's a problem with the output line, you can directly replace a hall line to solve this problem.

Can you not talk about the elastination of the industry so much?,I don't understand it.,If there's a problem with the line, then I'm going to change the line or change the graphics card.,If you change the graphics card, it's not recommended to change the machine.。 Speaking so industrially, I don't close the hole because my peers are late, I'm just a user.

You can try to change the line, if it doesn't work, it's a graphics card problem, and you can change the phone.

I still have a question, will the wire be sent if the screen is changed? Because the people in the repair shop said that the screen was broken and that they wanted to replace the screen, I had already paid for the screen.

Will send the line.
