My computer keeps flickering

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.

Typing is not easy, such as satisfaction, hope.

1. If there is a virus, don't go online and disconnect the Internet to kill and kill the virus.

2. The monitor and chassis are too close.

3. There is a problem with the refresh rate setting of the monitor, turn it up.

4 The power supply is too old and broken.

5. The speaker is too close to the display.

6. The graphics card is not plugged in well, and the contact is not good.

7. The cable behind the monitor, connected to the chassis, is not plugged in.

You can try them all.

How to solve the problem that the computer screen keeps flickering:Tools Raw materials.

Lenovo GeekPro 2020

Win7 64-bit Ultimate.

Method steps.

1. First, check the refresh rate of the computer screen.

Right-click on an empty space to select the screen resolution.

Click on the advanced settings, click on the monitor, if it is 60, it can be adjusted to more than 60, and about 70 should not be too high, otherwise the display will be damaged.

2. Then check whether there is interference in the surrounding environment, if there is a sound mobile phone, power bank.

Wait for the device, take it away, and then try to turn on the power to see if there is any current interference, if yes, you can pull the power cord a little farther away.

3. If none of the above methods can be solved, then you should check the graphics card driver.

If it's correct, update the driver, and if it's a desktop computer, see if it's a monitor connection problem.

How to solve the problem that the computer screen keeps flickering:1. Right-click in the blank area of our computer desktop --- Properties--Settings--Advanced --- Monitor.

2. You can see that the refresh rate of the monitor is set to "60", which is the reason why the monitor screen keeps shaking. Set the new frequency to "75" or higher, and then click to return to the desktop. Some laptops only have 60Hz this value,Then you don't need to set it,In addition, setting too high is easy to cause damage to the display,So everyone try to change it,If you haven't moved before,You can directly choose to start attacking with default。

Possible causes of computer screen flickering:1. The refresh rate of the monitor is incorrect.

2. The graphics card driver is not correct.

3. There is a strong electric field or strong magnetic field interference around the computer.

4. Problems with monitor hardware or power supply.

5. Computer viruses.
