What is the reason for the computer splash screen to the desktop

The following are the causes of the splash screen and how to solve it.

1. 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.

2. 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.

3. Inferior power supply or power supply equipment has been aged.

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.

4. The speaker is 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.

5. 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.

6. Poor contact of the graphics card.

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

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.

8. 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. Hope!!

1. Signal interference.

1. Whether the cable connecting the LCD monitor does not have a shielding coil, if there is no black protrusion that is anti-interference, it will also interfere with the screen.

2. Also check whether there is interference nearby, such as high-power audio and power transformer. Liquid crystal displays are susceptible to interference from strong electric or magnetic fields, and sometimes screen jitter is caused by magnetic or electric fields near the liquid crystal display.

Second, the frequency of the display problem.

1. Right-click on the desktop - > Properties - > Settings - > Advanced - > Monitor - > the screen refresh rate, CRT to 75Hz or above, laptop LCD screen to 60Hz.

2. In fact, the main reason for the screen shake of the LCD screen is that the refresh rate of the LCD is set below 75Hz, at this time, the screen often appears shaking, flickering, we only need to increase the refresh rate to more than 75Hz.

3. Graphics card driver problems.

1. Remove the graphics card, wipe it with an eraser, clean up the dust, and install the graphics card.

Go to the place where the computer is repaired and take a look.
