What happens when the computer screen flashes after a few minutes

The reasons why your computer screen occasionally flickers are as follows:

1.Check the refresh rate of the computer monitor, the right-click on the computer desktop, Properties, System, Advanced, and the refresh rate selected in the adapter;

2.If the screen flickers very large or has white or yellow bars, it can be that the picture tube of the computer monitor is damp, and in this case, the computer will run for a period of time to dry the moisture in the components; It is best to place the computer monitor in a ventilated place to avoid moisture affecting the service life;

4.Caused by voltage instability, the solution to the problem is to wait for the voltage to stabilize or connect to the Internet or add a voltage regulator;

5.If the interface of the computer graphics card is not in good contact or the heat dissipation of the graphics card is not good, in this case, it is necessary to open the main chassis and remove the graphics card to clean up the dust and install or replace the fan of the graphics card;

6.Determine the service life of the display, if it has been used for more than five years, it may be the service life of the monitor, and the display should be replaced;

Place. 3. Graphics card driver.

As a result, it is recommended to restart the computer after updating the graphics card driver.

4. Check whether there is any magnetic field interference around.

5. If the above method still doesn't work, it is recommended that you use the replacement method to check whether it is the problem of the graphics card or monitor.

You can test the screen and replace it, if the other one still flashes, then it is a program, magnetic field interference or graphics card problem;

If not, then it's a screen quality problem, just replace the screen.

Occasional flickering of a computer screen is usually caused by the following five situations, and the specific solutions are as follows:

1. Flickering caused by viral computer paralysis, this is a problem to be taken into account, your computer may appear garbled and the like, this basically has no choice, back up important data and then reinstall the system, and then ask the master to check and kill the backup files.

2. Check whether the connection cable between the host and the monitor is stable. This is a relatively simple and easy way to check first, shake it gently with your hand to check if there is any loosening, and if necessary, pull it off for cleaning to ensure that the connection is stable.

3. Eliminate the interference of external signals on the transmission signal. The transmission line of the monitor and the host will have a protruding magnetic coil to shield the external interference signal, when the external interference signal exceeds the allowable range, it will cause the screen to flicker, you can clear the objects near the computer that can produce magnetic field interference, if the screen is still flickering, we will proceed to the next step.

4. Flashing caused by BIOS factory setting restoration. Generally, this problem is relatively simple, you only need to replug the graphics card and memory modules, and then reinstall the system.

5. Flickering problems caused by hardware aging. This relatively new user can directly skim over,After all, the long-term use of electronic products will naturally cause the aging of hardware,The internal structure of the display and graphics card is aging,It may lead to the problem of flickering,The same method of replacing the display is eliminated,If the new display is normal,Then your old display will have a problem; Instead, something is wrong with your graphics card and other hardware. At this time, it is recommended that you replace the hardware in time to avoid damage to other hardware.

There are several possible reasons why your computer screen is flashing:

1.Graphics card driver issues: Incorrect or outdated graphics card drivers can cause the display to flicker. You can upgrade the latest version of the graphics card driver, or try rolling back to a previous version to see if that fixes the problem.

3.System setup issues: Some systems have power consumption adjustment features such as adaptive brightness enabled, which can affect the display of the screen. You can turn off these adjustments by going to the operating system's advanced display settings or control panel.

4.Display failure: If the above methods cannot solve the problem, it is likely that the display itself is faulty and needs to be repaired at a professional Vichai ruler repair point.

In addition to the above-mentioned reasons, there may also be problems caused by dirty graphics card interfaces. The solution is to turn off the computer and power off, take out the graphics card, gently brush the hail belt with a pencil eraser, wipe it from top to bottom, and then turn it on for testing after insertion. Troubleshoot based on specific circumstances.
