Users questions: My computer should be bought more than 2 years, less than three years, but recently the display is always flashing, do not know how, what are the plugs are inserted'll have to, and not unusual, that is, the old display Shem, ask you how this is going on here, how to solve?
Experts answer: There are many reasons can cause the screen Jitter or flicker, try the following: First, the display refresh rate set incorrectly if the refresh rate set too low, will cause the screen to shake, check method is to use right-click a blank area of desktop, from the pop-up menu Click "Properties" command into the display properties settings window. Single Click on the window "Settings" tab, the corresponding label in the subsequent pop-up page, click the "Advanced" button to open the advanced properties to set the display interface, and then click one of the "Monitor" tab, where you can see the display The refresh rate is set to "60", which is constantly causing the monitor screen jitter Reasons. The new frequency is set to "75" or more, and then click OK to return to the desktop on it. In fact, the main reason the monitor screen jitter monitor refresh rate is set below 75Hz due, the screen often appears jitter, flicker, we simply increase the refresh rate to 75H more than z, then the screen will not shake the phenomenon appeared. Second, the graphics card driver is not correct and sometimes we enter the computer's monitor refresh rate, but found no refresh rate to choose from, this is because the driver before the graphics are not caused by incorrect or too old. Purchase of computers vulnerable to the earlier time This problem, do not use this time to buy a computer with CD-ROM drive that can be made to the corresponding downloading the latest graphics card drivers, and then open the "system" of the Properties window, click the "hardware" window "Device Manager "button, the list of devices into the system interface. Right-click the Display interface card options, from the pop-up menu, click "Properties" command, and then in the pop-up graphics property window, click the "Driver" tab, and then in the corresponding tab page, click "Update Driver Program "button, the wizard prompts gradually after graphics driver update to the latest version The last system reboot the computer a bit, if the driver installed right, there will be a display refresh rate selection, and then set the refresh rate to 75Hz or more. Third, the magnetic field display jitter caused by the strong electric field can easily display or strong magnetic fields, if you use the above described The two methods still can not solve the jitter problem, you should suspect that the screen display near the jitter is caused by magnetic or electric field. In order to exclude any interference around the monitor clean computer can be moved around a table are empty, and then start the test, if the phenomenon of screen jitter Disappear, it means your computer to the original electric or magnetic field interference Fangyou Jiang, set something suspicious (such as subwoofer speakers, magnetic cup, etc.) away from the computer nearby. Then turn off the monitor and then re-opened several times in order to achieve the purpose of degaussing (now displays all the open with automatic degaussing function). Fourth, bad graphics card to open the case, the graphics card from the slot, the graphics card and then hand the finger at the Wax clean the dust, the best hosts to a thin, flexible brush, lightly dust the surface of all the cards cleaned, and then use a clean rubber surface in the finger wipe a few times, to clear the finger The surface oxide layer, and finally re-close the display card inserted into the motherboard slot, screw it to the chassis housing. Then boot test, the general failure to resolve. Fifth, the monitor displays the aging and sometimes the use of age has been high, there will be shaking. To test the internal display Whether the aging of electronic components can be connected to the fault of the monitor to test someone else's computer, if the fault is still disappeared, indicating that the display is bad need of repair. VI, poor power supply or power supply has been aging in many no-name computer components used in power work, materials are very poor, could easily lead to a computer circuit Poor or the power supply capacity can not keep up, when the system is busy, the display screen will appear in particular the phenomenon of jitter. Begin to age the computer when the power supply, are likely to cause the same problem. Then you can replace the power supply for testing.
