6. If it doesn't work, go and have a check.

My computer screen is always flashing, how to solve it?

Flash screen generally refers to the display problem on the computer monitor. When the computer is running, the screen flashes or flashes irregularly, and sometimes horizontal and vertical lines appear. Flash screen and snowflake screen are mainly caused by the problem of graphics card. Snowflake screen is similar to 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 the problem of the display itself is not ruled out.

cause

Flash screen and snowflake screen are mainly caused by the problem of graphics card, and the main problem of notebook screen is bad point. Be sure to ask the merchant a few bad points before buying. Snowflake screen is similar to TV, and flashing screen is like the problem of graphics card driver. The picture is complete, but the eyes are extremely uncomfortable.

magnetic disturbance

Put the computer in an environment without a strong magnetic field to see if there will be a splash screen.

Thoroughly disinfect

Some computer viruses will disturb the screen display, resulting in character inversion, screen jitter and other defects.

The refresh rate setting is incorrect.

If the refresh rate is set too low, the screen will shake.

Right-click the blank area of the system desktop-click Properties-click Settings-click Advanced, and select the "Monitor" tab in the pop-up interface for displaying advanced property settings. If you see that the refresh frequency setting of the monitor is less than 75, please set the frequency to 75 or higher.

The video card driver is incorrect.

If you find that there is no refresh frequency to choose from, it is because the driver of the graphics card is incorrect or too old. Do not use the driver in the CD that came with your computer at this time. Download the latest driver of the corresponding graphics card online, and restart the computer after updating the driver. If the driver is installed correctly, the option of displaying refresh rate will appear, and then the refresh rate will be set above 75Hz.

Poor contact of graphics card

If it is a discrete graphics card, take it apart, take out the graphics card, clean the gold finger with an eraser, clean the slot, and then plug it in.

Also check the screen cable.

test method

You can connect an external monitor, that is, connect the VGA port of the notebook. If the external monitors are the same, it is basically a graphics card. If the external monitor is normal, then the screen itself or the screen line is the most likely problem. Screen changing cable is very cheap, just tens of dollars! If there is something wrong with the screen, it will be very expensive. It is recommended to buy a new computer after the warranty period! And hardware failure, or replacement, or maintenance, have to find professionals.

Causes and solutions

1. The temperature of the graphics card is too high. Check whether the radiator works normally and remove the ash layer.

Second, the graphics card driver problem Update the graphics card driver or reinstall the driver (updating the driver is dangerous, which may cause the computer to fail to boot, so don't try without experience)

Thirdly, the refresh frequency of the display is set too low. When the refresh frequency of the display is set below 75Hz, the screen will often shake and flicker. If the refresh rate is set higher, such as higher than 85Hz, the phenomenon of screen jitter will generally not appear again. Fourth, the power transformer is too close to the monitor and chassis. When the power transformer works, it will cause great electromagnetic interference, which will cause screen jitter. This problem can be solved by keeping the power transformer away from the chassis and monitor.

5. Inferior power supply or power supply equipment has aged. The components and materials used in the power supply of many non-brand computers are poor in workmanship and materials, which can easily cause computer circuits to be blocked or the power supply capacity cannot keep up. When the system is busy, the display will especially appear the phenomenon of screen jitter. When the power supply equipment of the computer begins to age, it is easy to cause the same problem.

Six, the speaker is placed too close to the display, the magnetic field effect of the speaker will interfere with the normal work of the display, so that the display will produce screen jitter, color crosstalk and other magnetic interference phenomena.

Seven, the virus is at work. Some computer viruses will disturb the screen display, such as: character inversion, screen jitter, graphics flip display and so on. Screen jitter scripts that can be seen everywhere on the Internet are enough to make you as big as a cow.

Eight, the graphics card is in poor contact. After the video card is reinserted, the fault can be eliminated.

Nine. If this is the case with write-after cache caused by WIN95/98 system, disabling write-after cache for all drives in Control Panel-System-Performance-File System-Troubleshooting can fundamentally solve the problem.

Ten, power filter capacitor damage open circuit. ......

How is the computer always flashing?

Increase the refresh rate to ensure that there are no cats beside the monitor, and that the Land Rover's power adapter has returned to its original position. Right click, desktop _ _ properties _ _ advanced, display option, and increase the refresh rate, generally 75 Hz. In addition, the driver of the graphics card is installed correctly. The reason for the display jitter is that the refresh frequency of the display is set too low. When the refresh frequency of the display is set below 75Hz, the screen will often shake and flicker. If the refresh rate is set higher, for example, higher than 85Hz, the screen jitter will generally not appear again. The power transformer is too close to the monitor and the chassis, which will produce great electromagnetic interference when the power transformer works, thus causing screen jitter. This problem can be solved by keeping the power transformer away from the chassis and monitor. Inferior power supply or power supply equipment has aged.

The power filter capacitor is damaged. Open the chassis. If you see a bump on the top of the power filter capacitor (the largest capacitor on the circuit board), it means that the capacitor is broken and the screen jitter is caused by power failure. After changing the capacitor, the problem can be solved.

The computer keeps flashing from side to side. What happened? !

1 There is a magnetic field near your monitor (mobile phone, etc.). ). Take away the mobile phone, etc. 2. The screen refresh frequency set by the monitor is incorrect. Reset. Degaussing just find a degausser for TV maintenance personnel, or press the function key of the display panel, find the degaussing item on the screen, and press it to be OK. The easiest way is to take a magnet and shake it a few times in the magnetized place. The more your screen flashes, the more programs flash, indicating that the graphics card is not very good, or integrated graphics card. Try changing the graphics card for the former and the driver for the latter. ...

Why does my computer flash?

Don't you have a graphics card driver installed? Right-click my computer, select Manage, and then click Device Manager to see if there is a yellow problem. If so, it means that a driver is not installed on your computer. The splash screen should be a graphics card driver, and it is ok without installing the next graphics card driver.

What's the matter with the computer flashing for a while?

There are many reasons why the splash screen crashes. First, the hardware problems of the graphics card itself, such as slight damage to the video memory of the graphics card, poor working material or poor compatibility of the graphics card, will greatly reduce the electrical performance of the graphics card. If this happens, it is best to confirm it by replacement. Because of the use of AGP8× graphics card, users can also adjust the working rate of graphics card to AGP4× in BIOS, and it is best not to overclock the graphics card easily. In addition, the reason for the crash when playing 3D games may also be that the graphics card is not cooling well. Please carefully check whether the graphics card radiator is normal.

First, the driver problem, which is also an important reason for the screen display, mostly appears after changing the driver version of the graphics card, or it may be caused by the damage of the driver file. The solution is simple. Reinstall the driver that has passed the Microsoft WHQL certification, and the version does not need innovation. The first thing to check when displaying a screen is the graphics card driver, which conforms to the principle of soft first and hard later.

Second, the temperature problem, this problem is not only because the motherboard's graphics card, processor, memory and even chipset are overheated, which often happens in summer, but in winter, if the radiator falls off and the fan stops running, it is likely that the indoor hard disk temperature is too high, which cannot be ignored. It is also recommended to open the chassis to check the installation of each radiator, try to open the chassis to run the game, and see if the screen will be drawn again, and the fault will disappear after a period of time.

Third, power supply, including power supply and AGP/PCI-E 16X power supply for the motherboard. If the graphics card does not get enough pure current, the screen may also appear. The solution is to disconnect the CD-ROM drive, independent sound card and other unnecessary hardware to reduce the load of the whole machine and try again.

Fourth, there are many reasons for graphics card problems. It is possible that the graphics card BIOS is defective, which can be solved by refreshing VGA BIOS; It is also possible that the main memory is damaged, which is a common situation. Individuals have no solution. In addition, if it is a flower screen caused by core damage, the graphics card can only be scrapped; Maybe the golden finger is oxidized or dusty, which is the luckiest thing. Clean it up. The oxidized part can be wiped with rubber and cleaned with anhydrous alcohol, and the fault will disappear. Another problem that can't be ignored is the capacitance on the graphics card. Many graphics card screens are spent because of capacitance, and some manufacturers even dumped them (the famous screen king Geng Sheng). In recent years, emerging graphics card manufacturers have adopted some capacitors that are very sensitive to temperature in order to save costs. The screen will be displayed when the temperature drops in winter. Theoretically, the fault will be eliminated after replacing the capacitor, but it is recommended to contact the dealer for replacement or return to the factory for maintenance.

The display screen is an extremely common fault for many reasons. The failure phenomena caused by different reasons are also different, and the solutions are also different. In the text mode, the flower screen is characterized by chaotic characters, while in the graphic mode, it is usually characterized by graphic layering, and horizontal bars will be generated due to internal or external interference. The following are some thoughts and experiences for your reference.

The 1. display produces horizontal stripes: There are two main reasons:

1) External interference, such as electric spark or high-frequency electromagnetic interference near the place where the monitor is used, will cause white stripes on the monitor display screen. Solution: Avoid using the monitor in this case;

2) Internal interference will cause black stripes on the display screen of the monitor. In this case, you can open the case and check whether there is poor contact inside the display, power output or output transformer. There are many professional technologies involved in this situation, so it is best to ask professionals to repair it.

2. The display screen is caused by incorrect display resolution setting: when the display resolution setting in WIN3 is incorrect. X and WIN95, when Windows is started, there may be screen failure, that is, screen delamination, jitter, and even serious black screen crash. Solution: enter the settings of WIN3. X or WIN95, and reset the display mode of the monitor.

3. Conflict between the graphics card and the Chinese system: This happens when you exit the Chinese system, and there is no response when you press the button at will, which is similar to a crash. Solution: At this time, enter "mode C080" to solve.

4. The cooling effect of the main control chip of the graphics card is poor: this will also lead to the failure of the screen, and the treatment method is as follows ......

The computer is always flashing, how is the resolution automatically adjusted?

1, graphics driver and hardware do not match. It is recommended to uninstall the graphics card driver and reinstall it.

2. The resolution of the application software in the computer is automatically adjusted. For example, games and design software need to be checked.

3. There is something wrong with the display. To reset the resolution manually, click the right mouse button in the blank space of Desktop-Computer Desktop-Screen Resolution-Advanced-Monitor-Set Screen Refresh Rate.

What causes the computer to keep flashing?

The method of repair.

The first step is to see if dsound.dll and ddraw.dll are still in system32.

If you go to the web page, the reason for flashing the screen is. Basically, even if the file is still there, it is already incomplete.

The method of manual deletion is.

A. If you can't find these two files, you can go directly to the second step.

B. If you see these two files, you can't put them directly in the recycle bin. Give it a try.

Enter regsvr32-u dsound.dll and regsvr32-u ddraw.dll in the operation.

Then delete it manually to see if it works.

C. If it still cannot be deleted, enter the safe mode to delete. Press f8 on the windows startup screen to delete safe mode. undoubted

Step two. After it was deleted. Download a Jinshan first aid kit. Then update to the latest version.

It is strongly recommended that all people who use the 360 first aid kit switch to this one. Because 360 has a feeling similar to Kaspersky. I'd rather kill the wrong person. So many dll files in system32 have been deleted.

Then, the Jinshan first aid kit added the function of powerfully repairing ddraw.dll and ddsound.dll in the update of 3.20.

Then, you can fix all the options it prompts to fix. It won't change your system much. Remember to turn off your firewall or 360 before repairing it. Otherwise there will be conflicts.

It is certainly possible to follow the above method. . .

The computer keeps flashing.

Try the following.

1. The display refresh rate is set incorrectly.

If the refresh rate is set too low, it will cause screen jitter. The checking method is to click the blank area of the system desktop with the right mouse button, and click the "Properties" command from the pop-up right-click menu to enter the display property setting window. Click the "Settings" tab in this window, then click the "Advanced" button in the corresponding tab page that pops up later to open the advanced attribute setting interface of the display, and then click the "Display" tab, from which you can see that the refresh frequency of the display is set to "60", which is the reason for the continuous jitter of the display. Set the new frequency above "75", and then click OK to return to the desktop.

In fact, the main reason for the display screen jitter is that the refresh frequency of the display is set below 75Hz. At this time, the screen often appears jitter and flicker. We just need to increase the refresh rate to above 75Hz, and the screen jitter will not appear again.

Second, the graphics card driver is incorrect.

Sometimes we enter the refresh frequency of the computer monitor, but we find that there is no refresh frequency to choose from. This is because the driver of the front graphics card is incorrect or old. This problem is easy to appear when computers are purchased earlier. At this time, don't use the driver in the CD provided when you buy the computer. You can download the latest drivers of the corresponding graphics card from the Internet, then open the properties window of the system, click the device manager button in the hardware window to enter the device list interface of the system. Right-click the graphics card option in the interface, click the "Properties" command in the pop-up right-click menu, then click the "Driver" tab in the pop-up graphics card property setting window, and then click the "Update Driver" button in the corresponding tab page. Then, according to the wizard prompts, gradually update the graphics card driver to the latest version, and finally restart the computer system. If the driver is installed correctly, the option of displaying refresh rate will appear, and then set the refresh rate.

Thirdly, the display jitter caused by magnetic field interference

The display is easily disturbed by strong electric or magnetic fields. If the above two methods can't solve the jitter problem, it should be suspected that the screen jitter is caused by the magnetic field or electric field near the display. In order to eliminate all interference around the monitor, you can move the computer to an empty desk and then conduct a power-on test. If the screen jitter disappears, it means that there is strong electric or magnetic interference in the original place of your computer. Please be good at finding suspicious things near the computer (such as subwoofer, magnetic cup of speaker, etc.). Then turn off the monitor and turn it on several times to achieve the purpose of degaussing (at present, all monitors have automatic degaussing function when turned on).

Fourth, the graphics card has poor contact.

Open the chassis, take the graphics card out of the slot * * *, and then wipe off the dust on the gold finger of the graphics card by hand. It is best to find a soft fine brush to gently remove all the dust on the surface of the graphics card, and then wipe it on the surface of the golden finger several times with clean rubber to remove the oxide layer on the surface of the golden finger. Finally, re-insert the graphics card into the slot of the motherboard and fix it on the chassis shell with screws. Restart the machine test, and the general fault can be solved.

Five, the display aging

Sometimes, due to the aging of the monitor used, jitter also occurs. In order to check whether the electronic components inside the monitor are aging, you can connect the faulty monitor to someone else's computer for testing. If the fault still disappears, the monitor is broken and needs maintenance.

Six, inferior power supply or power supply equipment has been aging.

The components and materials used in the power supply of many non-brand computers are poor in workmanship and materials, which can easily cause computer circuits to be blocked or the power supply capacity cannot keep up. When the system is busy, the display will especially appear the phenomenon of screen jitter. When the power supply equipment of the computer begins to age, it is easy to cause the same problem. At this time, you can change the power supply for testing.

Seven, the virus.

Antivirus comes from the Internet.
