The computer automatically flashes the screen, what happens when the computer always automatically f

The specific causes and solutions are as follows:

1. Caused by current interference. This is the case when all displays (including TVs, projectors, etc.) flicker. A relatively simple test method is to use a notebook, if it is plugged in and the power supply will flash, and if it is not connected to the power supply, it will not flash, you can judge that it is current interference, which is more common in industrial electricity, and the simpler way is to remove the ground wire on the power plug.

2. After entering the system, it has been shaking. This is usually the case when the refresh rate is set incorrectly. Today's monitors can generally be adjusted automatically, and you can press the "auto" button on the monitor to automatically adjust the high display.

3. Some monitors don't have an auto-adjust button, so you need to change the properties of the display. Right-click on the blank space of the desktop, select "Properties", select the "Settings" tab, click the "Advanced" button, select the "Monitor" tab in the pop-up dialog box, and select "Screen Refresh Rate" to "60 Hz". If it still flashes, change it to a different "screen refresh rate".

Me too,,Encounter this kind of problem of opening the software to automatically close the splash screen,Reinstall the system several times,Every time you shut down and boot up, it appears again。 Later, I found that the software was in conflict with the system, uninstalled a rogue software, and several unwanted software that was automatically upgraded and updated was normal. If you think about it, it's been a bit of a lately new phenomenon with a lot of software.

1. Clean up the equipment with electromagnetic interference, if there is a strong magnetic field, it will cause the computer screen to flicker. If there is still a flickering screen, you need to put the computer in an open space or empty room without electronic equipment for inspection, and then restart the computer monitor, the monitor will have an automatic degaussing function during the switching process.

2. If the flickering problem exists for a long time, it can be concluded that the display is damaged, or the connected power supply is damaged, because it needs to be disassembled, you need to find a professional to repair it, and the power supply problem can be replaced by buying the same model of power cord.

3. Install or update the graphics card driver, when the graphics card driver is missing or the version is backward, it will cause the graphics card to display an error, and the refresh rate change option is missing in the settings, etc., we need to check and install the latest version of the driver by ourselves.

4. If the refresh rate of the display does not match the configuration of the display, it will also cause the problem of constant flickering. Right-click on the desktop, select Display Settings, click Change Display Settings, and finally select Advanced Settings. After entering the advanced settings interface, you can see that the refresh rate of the monitor is set to "60", and change the value to "75" or more, you can solve the reason why the display flashes black screen.

However, some brands have displays up to "60", so you don't need to change the value.

There are usually three reasons for the flickering screen of a computer.

1. Splash screen caused by screen backlight.

Cause: This situation occurs due to the instability of the high-voltage board that supplies power to the screen backlight or the solder joint connection at the lamp joint is not strong and ignites.

Solution: Replace the high-voltage plate to solve the flickering screen.

2. The flashing screen caused by the motherboard charging switching circuit.

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.

Solution: Repair the components of the motherboard's charging circuit to fix the fault, or replace the power adapter.

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

The specific fault performance is: Generally, there will be a bright line under the laptop screen, and after a while, the bright line will evolve into a full-screen flash.

The solution: can only be replaced with a new LCD screen.

Three places, the first drive, the second data line, and the third power supply, most of them are caused by poor contact.

You can see if it's water, or someone else falls and you don't know, or it's caused by insufficient memory, and you really need to repair it, go to the after-sales service to see.

The computer always flashes automatically, which means that there is a problem with the computer screen, and the computer screen needs to be taken back for repair.

To add that, in addition to the computer itself, a faulty display line can also cause a flickering screen.

Computer flickering screen is generally due to the problem of the filter capacitor on the power board of the monitor, which can be alleviated by adjusting the brightness of the monitor to 100 and the contrast ratio of 100, and if conditions permit, you can open the back cover of the monitor to replace the capacitor.

Is the display screen flashing, sometimes it is a voltage problem, the voltage is not enough, or sometimes you have a problem with the power supply, you first see if there will be other power supplies in the computer socket you are connected to!!

Causes of display jitter.

The monitor refresh rate is set too low.

When the refresh rate of the display is set to be lower than 75Hz, the screen often shakes and flickers, so adjust the refresh rate appropriately, such as setting it higher than 85Hz, and the screen shaking will generally not appear again.

The power transformer is too close to the monitor and chassis.

When the power transformer is working, it will cause large electromagnetic interference, which will cause the screen to shake. Keeping the power transformer away from the chassis and display can solve the problem.

Inferior power supplies or power supply equipment are aging.

The workmanship and materials used in many miscellaneous computer power supplies are very poor, which can easily cause the circuits of the computer to be poor or the power supply capacity can not keep up, and when the system is busy, the display will especially appear screen shaking. When the power supply equipment of the computer starts to deteriorate, it is easy to cause the same problem.

The speakers are placed too close to the monitor.

The magnetic field effect of the speaker will interfere with the normal operation of the display, causing the display to produce magnetic interference phenomena such as screen shake and color crossing.

Viruses do the trick. Some computer viruses can disrupt the screen display, such as: character inversion, screen shaking, graphic flipping display, etc. The ubiquitous screen shake scripts on the internet are enough to make your head as big as a cow after a hit.

The graphics card is not in good contact.

After the graphics card is reinserted, the fault can be troubleshooting.

Win95 98 system after write cache caused.

If this is the case, disabling all drive write-back caching in Control Panel - System - Performance - File System - Troubleshooter will resolve the problem at all.

The power filter capacitor is damaged.

Open the case, and if you see the top of the power filter capacitor (the largest capacitor on the board) bulging up, then the capacitor is broken, and the screen shake is caused by a power failure. Once the capacitor is replaced, the problem can be solved.

The common reasons for screen failures such as screen flickering and screen shake are: first, the quality of the screen itself, the screen is aging or inferior products, LG brand screens have the most chance of this problem, this situation is the most common, and second, the screen line contact will not.

If you have a spare display, you can change it.
