What s the deal with streaked and flickering on a computer screen?

1.Streaks on the computer screen: There are two main reasons for this:

1) External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;

2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2.Improper display resolution setting causes streaks on the computer screen: When the monitor is set incorrectly in the resolution of win95, the computer screen may be blurred when Windows is started, that is, the picture is layered, shaking, serious and even black screen of death.

Solution: Enter the setup or enter the security mode of win95, and reset the display mode of the display.

3.Conflict between the graphics card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and there is no response to random keystrokes, similar to a crash, processing method: enter modec080 at this time to be solved.

4.Poor heat dissipation effect of the main control chip of the graphics card: This will also cause streaks on the computer screen, and the treatment method is to improve the heat dissipation performance of the graphics card.

5.The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the computer screen will also be blurred.

6.Video memory corruption: When the video memory is damaged, there will be a blurred screen when the system boots up.

7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.

The above is the solution to the streak flickering and blurred screen on the computer screen, if you find that the above methods cannot be solved, and the computer screen has been used for a certain number of years, it is best to change the computer screen, and the screen is more beneficial to the user's eyes.

Cause. 1. Subject to external interference.

It is due to strong electromagnetic interference in the vicinity where the display is placed, such as electric sparks and high-frequency electromagnetism. If the intensity of interference is very high, it will cause the entire screen of the monitor to produce white horizontal streaks; If the intensity of the interference is not high, it can be characterized by a severe change in one corner of the display.

Solution: When these two situations occur, we must first focus on checking the surroundings of the display site to eliminate the equipment with strong magnetic interference, and in general, the problem can be solved.

Cause. 2. Subject to internal interference.

The performance of internal interference is very different from that of external interference, and if the display is interfered with, it will make the display screen of the monitor appear black horizontal stripes, and it is more serious.

Solution: In this case, you can open the case to check whether there is any bad contact inside the display, and whether there is any problem with the output end of the power supply or the output transformer.

Cause. 3. The service life of the display is too long.

If the internal capacitor is too old, it will deteriorate and fail, resulting in too slow start-up, a dull screen, and blurred fonts. At this time, as long as the aging capacitor is replaced, the fault can generally be eliminated, but because it is also a very high-tech work, it is recommended to send it for repair.

Cause. Fourth, the display resolution is set improperly.

There may also be a serious computer screen streak fault, this kind of fault generally appears on the older machine, if the computer is working under the Windows system, you can press the F8 key to enter the system's security mode, reset the display mode of the monitor, and generally be able to eliminate the fault after restarting.
