What are the reasons for the display of a flower screen on a computer monitor

Computer monitor flower screen is a very common fault, there are many reasons, different causes of the fault phenomenon is also different, the solution is also different. In the text mode, the flower screen is characterized by character confusion, which is usually represented by graphic layering in graphic mode, and horizontal stripes can be generated by internal or external interference.

1. The display produces horizontal stripes: There are two main reasons:

1 external interference, such as the display of the use of the site near an electric spark or high-frequency electromagnetic interference, this interference will make the display of the screen to produce white horizontal stripes. Treatment method: Avoid the use of the display in this case;

2) Internal disturbances, this interference will make the display screen appears black horizontal stripes, in this case, you can open the chassis to check whether there is bad contact inside the display, power output or output transformers, and so on, because the reasons for this situation related to more professional technology, So it is better to ask the professional to give the repairs.

2. Display resolution incorrectly caused by the screen: when the display in the win3.x and WIN95 resolution settings are not correct, when you start Windows may appear flower screen fault, that is, the screen layering, jitter, serious even the phenomenon of black screen crash.

3. The display card and the Chinese system conflict: this kind of situation when exits the Chinese system will appear the flower screen, the random keystroke all does not have the reaction, resembles freezes, the processing method: At this time the input MODEC080 can be solved.

4. Display card's main control chip heat dissipation effect is bad: This also can produce the flower screen fault phenomenon, the processing method: improves the display card the heat dissipation performance.

5. Video memory speed is too low: When the video memory speed is too low to match the speed of the host, it will also produce a flower screen phenomenon, processing methods: Replace more high-speed video memory, or reduce the speed of the host.

6. Video memory Damage: When the video memory damage, the system will be started when the flower screen Chaos character phenomenon, processing method: Must replace the memory bar.

7. Virus reason: In some virus outbreak will also appear flower screen, processing method: Antivirus can be eliminated with anti-virus software.
