What is the reason of the notebook flower screen?

The question is a simple one and there is nothing to say. Because the internal heat of the notebook is bad, the temperature is too high to cause the graphics chip to burn, the memory chip burned, or the chip welding because of the temperature open welding phenomenon, maintenance words are easy to find problems, but this kind of flower screen failure, if you do not need to change the chip in the case of maintenance If it involves updating the price of the film is higher, can not be specifically determined.

Basically caused by the notebook flower screen is the above situation, of course, there are some of the following circumstances, the proposal or simply their own judgment, sent to the sale after look at it. Under normal circumstances, as long as the notebook can be repaired free of charge, the 08 notebook renewal is still in the case of protection.

Other classes cause the notebook to flower screen:

Software problems

First, the problem of driving

Graphics driver error caused by the flower screen: there is image contour, but the color distortion, blurred.

Because the laptop driver is not a graphics chip company to write, chip companies in the provision of chips, the driver of the problem to the notebook computer manufacturers to write, so there may be a certain degree of compatibility problems. At the same time, notebook computer drive to release a very slow, generally six months or one year update. The first thing we can do is try to see if running other 3D programs also have the same flower screen, black screen, and if the problem disappears, it can be considered a compatibility issue. At the same time, the driver file is damaged or missing, may cause the graphics card to run a false panic, Huati, black screen and so on, to solve this problem simply uninstall the original driver, reinstall the driver can be.

Second, third party software

After the overclocking software is turned on, if the video memory frequency exceeds the head, the picture appears the mapping error, the flower screen phenomenon is very normal, when the serious will also cause the panic. Because video memory works at abnormally high frequencies, the higher frequencies only make the job unstable, especially when data is read and written. At this point, we just need to lower or restore the default frequency.

Of course, the above mentioned is that we are troubleshooting notebook computer screen fault most basic methods, if the debug failure is still, we should turn from the hardware aspect. On the author's personal experience, the phenomenon of notebook computer screen is generally a hardware problem, software problems in the compatibility of more.

Hardware issues

One, LCD signal line contact is poor: simple screen can not cause a flower screen, only red screen, green screen, gray screen or image beat, it may be screen.

This is our first step in checking the hardware. Huati, black screen phenomenon irregular appearance, or after tapping and pressing the keyboard surface after the failure disappears, this is often due to the LCD signal line and interface caused by poor contact results. We just need to reseat the corresponding interface problem to eliminate.

Second, oxidation reaction

Generally this is due to the laptop in the environment or long-term use of the result is easy to appear, when dealing with, we first LCD signal line interface out, with the eraser joint of the gold finger, and the interface is stained with a small amount of anhydrous alcohol cotton to scrub, The aim is to remove adverse contact phenomena caused by oxidation or contamination. After processing, and then the line back up, check whether the plug can be.

Third, video memory problem

Video memory caused by the flower screen:

(1) Virtual welding memory

A, is the vertical bar lattice, and the color is single, full screen upside down is not necessarily.

(2) Memory bad: A, there is a lattice, but the bar is mixed with other colors, and full screen up and down the head.

B, sometimes blocky, local color block (but not colored stripes)

C, in the logo interface, the system starts normally, but only when the application is loaded (Welcome to use and desktop).

As a result of some notebook computer graphics card memory using dynamic video memory technology (that is, dvmt,dynamic Memory Technology), the use of part of the memory capacity for video card memory. In the actual operation process, possibly due to the internal structure of memory damage, when to select this part as video memory, the chip and the obvious existence of data exchange often error, resulting in the flower screen, black screen, and even the crash phenomenon. When this happens, we can use the substitution method to replace the same specification of memory for inspection. Of course, if the video memory is integrated on the motherboard, we can only send repair.

Four, the video card caused by the flower screen:

(1) Virtual welding card:

A, the current run full, diagnostic card code 90, but not light machine.

B, the current running full, should be on the machine but shown as a gray screen (external also so)

C, the current run full, external flower screen, the screen for the gray screen.

(2) Bad card:

A, the logo on the flower, messy flowers. Sometimes there are snow patterns around the logo.

B, sometimes stripes, vertical bars.
