There can be many reasons why the computer screen suddenly flickers rapidly, it may be because the computer screen is damaged, it may be because the graphics card driver is broken, or it is because the CPU is overloaded.

Dear, hello, I'm glad to answer for you, but the laptop reset screen keeps flashing: it may be that the refresh rate of the laptop computer is set too low, which causes the screen to shake. Workaround:

1. The way to check the computer splash screen is to right-click the blank area of the system desktop, click the "Properties" command from the pop-up right-click menu, and enter the property setting window of the monitor; 2. Click the "Settings" tab in the window, and click the "Advanced" button in the corresponding tab page that pops up behind it to open the advanced attribute setting interface of the monitor; 3. Next, click on the "Monitor" tab in the advanced property settings interface, from which you can see that the refresh rate of the monitor is set to "60", which is exactly what causes the monitor screen to keep shaking. At this time, set the new frequency above "75", and then click OK to return to the desktop. 1.

Because the power socket is poorly contacted and interfered by signals, such as electromagnetic wave interference and electrostatic action; 2.The refresh rate of the computer screen is too low or the graphics card driver is not installed or damaged; 3.The power supply connected to the computer is of inferior quality; 4.

There is a problem with the computer hardware. Since the flickering or shaking of the computer screen will not only cause eye fatigue, but also cause damage to the user after a long time, it may also cause damage to the system, so it is necessary to find a solution, so here are a few examples of solutions:1:

Poor contact: Check whether the power cords of the main unit and the monitor are secure. 2: Signal interferenceWhen using the computer, pay attention to the surrounding environment, and do not place the computer in a place where electromagnetic waves may be emitted.

3: The reason why the refresh rate of the screen is too low is that the refresh rate of the monitor is set below 75hz, we only need to increase the refresh rate to more than 75hz, then the phenomenon of computer screen shake will no longer appear. The steps are as follows:

Right-click on the desktop, select [Properties] [Settings] [Advanced] [Monitor] [Screen Refresh Rate], and select 75Hz or above (Note: The LCD screen of the laptop can be adjusted to 60Hz). 4: Incorrect Graphics Card DriverSometimes when we change the screen refresh rate, we find that there is no refresh rate to choose from, which indicates that the current graphics card driver is incorrect or too old.

At this time, it is best not to use the driver in the CD when you buy the computer, but to the latest version of the driver of the corresponding graphics card on the Internet, open the "Device Manager", select the display card option in the device list interface, right-click to check the "Properties" command, and then in the window, click the "Driver" tab, and then click the "Update Differential Macro Driver" button, and then update the graphics card driver to the latest version according to the wizard step by step, and finally restart the computer, if the driver is installed appropriately, The display refresh rate option will appear, and then set the refresh rate to 75Hz or higher to solve the problem. 5: The solution to the flickering of the computer screen caused by the inferior power supply or the aging of the power supply equipment.

This phenomenon is not necessarily a problem, does the screen flash when you move it when it is not flashing? If there is, it is possible that the cable is loose and the contact is not very good, if it is not possible, it is a problem with the screen. In both cases, it will be sent for repair.

If you reinstall the graphics card driver, it still can't solve the problem.

That's the problem with the screen.

What to do if your computer monitor keeps flickering.

The computer screen keeps flashing like a refresh, first check whether your graphics card driver is installed, if it is normal, try the following methods:

First, the screen refresh rate is low: open the Display Properties panel, click Advanced, then select the Monitor tab and put it inside"Only the highest refresh rate supported by the display is displayed"Click the refresh rate marquee box next to it, and then click the refresh rate marquee box to select the highest frequency in it.

Second, electromagnetic interference display: is there any large electrical appliances next to it, or a speaker with poor demagnetization, the electromagnetic of such appliances will interfere with the display of the display. Just keep the monitor away from such electrical interference.

Third, display aging failure: If the above two methods cannot be solved, it may be display aging or failure, and it is best to send it for repair.
