The Win7 system computer screen is always the cause of the flash screen color change and its solution

Reason one:

caused by aging of the graphics card Solution: The integrated graphics card is likely to have such a discoloration of the computer screen, and the screen is not only purple but not only blue. Some old PCI graphics cards are also like this. It is recommended to change the graphics card.

Reason 2: Poor contact of the transistor on the display board

Solution: The problem of discoloration of the computer screen can be solved by removing the solder.

Reason three: The display shows the change of the three primary colors

That is, when there is no signal, the color has been changing all the time. This is the machine factory mode, and each display exits the factory mode. The method is different, so it is best to call to ask the supplier.

Solution: Estimate the screen line may be large, the connection is not good, the next display test software, test your display, if the display is good, reload the video card driver to check your display Connect the upper and lower nuts on the back of the computer with the cable from the main unit. The problem is solved.

Reason 4: Overheating of the graphics card causes a fault

Since the graphics chip generates a lot of heat during operation, it needs to have better heat dissipation conditions. If the cooling fan is damaged, the graphics card will not overheat. jobs. Overheating failure of the graphics card usually causes system failures such as crashes and screens.

Solution: If the graphics card is overheated, just replace the cooling fan.

Reason 5: Graphics card driver failure usually causes system instability, screen, text image card incomplete, etc.

Graphics card driver failure mainly includes graphics card driver loss, graphics card driver The program is not compatible with the system, the graphics card driver is damaged, the graphics card driver cannot be installed, and so on.

Solution: For the graphics card driver failure, first enter the “Device Manager” to see if there is a driver for the graphics card. If not, reinstall it. If there is, but there is “!” on the graphics card driver, the graphics card driver is not installed, the driver version is wrong, the driver is not compatible with the system. Generally remove the graphics card driver to reinstall. If there is still “!” after installation, you can download the new driver installation. If the graphics card driver cannot be installed, there is usually a problem with the driver or a problem with the registry.

Reason 6: The display is magnetized and usually has a stain.

The cause of the display being magnetized is mainly because the display is close to the magnetic object, or after the display is moved, the deflection coil inside the machine is shifted. Or caused by damage to the degaussing circuit. The display is magnetized and demagnetized using the degaussing function of the display itself.

Solution: The elimination method is: open the function menu of the display, then select the degauss option and perform degaussing, then hear the display sounding “& 砰 rd , , , , , , , , , , , , , , , 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器 显示器Degaussing.

The above six are the main reasons for the failure of the Win7 system computer screen and the solution to the problem. If you encounter the same problem, please follow the above method.
