In our life, when the laptop is turned on and off, it is best to protect the keyboard, do not let the water enter the inside, or the fan is clear. The following system home Xiaobian introduces the problems and solutions of the seven kinds of computer monitors that keep flashing. 1. The display refresh rate setting is incorrect. If the refresh rate setting is too low, the screen will be shaken. The check method is to right-click the blank area of the system desktop and click the "property" command from the pop-up menu. Go to the property settings window of the display. Click the "Set" tab in the window, and click the "Advanced" button in the corresponding depth win7 system tab page of the dan to open the advanced property setting interface of the display, and then click the " The monitor "tag, from which you can see that the display's refresh rate is set to "60" , which is why the monitor screen is constantly shaking. Set the new frequency to "75" above, then click OK to return to the desktop. In fact, the main reason for the monitor screen jitter is that the display refresh rate is lower than 75Hz. At this time, the screen often appears jittery and flickering. We only need to increase the refresh rate to above 75Hz, then the screen jitter will not be Will appear again. Second, the graphics card driver is not correct Sometimes when we enter the computer's display refresh frequency, but found that there is no refresh frequency to choose from, this is because the driver of the previous graphics card is not correct or too old. Computers with earlier purchase time are prone to this problem. Do not use the driver on the CD that came with the computer when you purchased the computer. You can download the latest version of the driver card on the Internet and open the Properties window of the "System". Click the "Device Manager" button in the "Hardware" window to enter the system's device list interface. Right-click the display card option in the interface, click the "property" command from the pop-up context menu, and then click the "driver" tab in the dan's graphics card properties settings window. Click the "Update Driver" button on the corresponding tab page, and then gradually update the graphics driver to the latest version according to the wizard prompts. Finally, restart the computer system. If the driver is installed properly, the display refresh rate will appear. Select the item, and then set the refresh rate to 75Hz or more. Third, the magnetic field interference caused by the display jitter monitor is very susceptible to strong electric field or strong magnetic field interference, if you can not solve the jitter problem using the two methods described above, then you should suspect that the screen jitter is caused by the magnetic field or electric field near the display. In order to eliminate all the interference around the monitor, you can move the computer to a table that is all around, and then start the test. If the jitter of the screen disappears, it means that there is a strong electric field or strong magnetic field interference in the original place of your computer. Please take suspicious things (such as the speaker's subwoofer, magnetized cup, etc.) from the computer nearby. Then turn off the display and re-open it several times to achieve the purpose of degaussing (the current display has automatic degaussing function when it is turned on). 4. If the display card is not properly connected, open the case, pull the display card out of the slot, and then Wipe the dust from the gold finger of the display card by hand. It is best to find a soft fine brush and gently remove all the dust on the surface of the card. Then wipe it off with a clean rubber on the surface of the gold finger to remove it. The oxide layer on the surface of the gold finger will finally reinsert the display card into the motherboard slot and secure it to the chassis housing with screws. After the test is turned on, the general fault can be solved. Fifth, the display aging sometimes due to the use of the display is too old, there will be movement. In order to verify that the electronic components inside the display are aging, the faulty display can be connected to someone else's computer for testing. If the fault still disappears, the display is broken and needs to be repaired. Sixth, poor quality power supply or power supply equipment has been aging Many components used in computer power supply, the materials used are poor, easy to cause the ghost xp system computer circuit is not smooth or power supply can not keep up, when the system is busy, the display will especially The phenomenon of screen jitter appears. When the computer's power supply starts to age, it is also likely to cause the same problem. At this point, you can replace the power supply for testing. Seven, the virus is blamed Some computer viruses will disturb the screen display, such as: character inversion, screen jitter, graphics flip display. Screen jitter scripts that can be seen everywhere on the Internet. This article comes from [System Home] www.xp85.com
