When the computer opens some programs, the screen will flash in black and white

The computer configuration is not good, maybe your graphics card is too low.

Well、I'll do it myself、

There are just a few such questions

First of all, I will teach you how to distinguish whether it is a monitor or a host problem, unplug the monitor from the host, and see if it flashes when there is "no signal".

If you find that it's a computer problem.、You can reinstall.、Or use the driver home.、Driver wizard.、Because、I believe,It's a win98 computer system.、It's impossible to drag IE.、Will make IE splash screen,

If it's a display issue, then please see:

First, the connection cable, maybe the contact is not good, you can replace the connection cable to try, two, the internal problems of the display

Inside the display: power supply, screen, motherboard,

When the computer flashes the screen, it is the short circuit of the two plates in the screen, the use is sure to be error-free, it must be some problems with the factory, because, I believe, no one, will have nothing to take the monitor apart, when the game is played, the screen flashes: basically the screen is caused (maintenance, need to pay, 80% of the cost of the monitor) is not cost-effective at all, it is better to buy a new one

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

1) External interference: If there is an electric spark 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.

3) The service life of the display is too long: If the internal capacitor is too long, it will age and fail, resulting in too slow start-up, gray screen, and blurred font. 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.

4) Improper setting of display resolution: there may also be serious streak faults on the computer screen, this kind of fault will generally appear on older machines, if your computer is working under the Windows system, then you can press the F8 key to enter the security mode of the system, reset the display mode of the monitor, and generally be able to troubleshoot after restarting.

Second, the computer screen flickering horizontal stripe solution.

1. Improper display resolution setting causes streaks on the computer screen: When the display 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 safe mode of win95, and reset the display mode of the monitor.

2. Conflict between the graphics card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and the random keystrokes will not respond, similar to a crash, and the processing method: enter modec080 at this time to be solved.

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

4. The 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 the phenomenon of the computer screen blurring, and the solution: replace the higher speed video memory, or reduce the speed of the host.

5. Video memory damage: When the video memory is damaged, there will be a phenomenon of blurred screen and chaotic characters when the system starts.

6. Virus cause: There will also be a blurred screen when some viruses occur, and the treatment method is to eliminate it by antivirus software.

The flickering of the screen is mainly due to the aging of the backlight tube, and in rare cases, it is due to the abnormal high-voltage circuit; The screen flickered, could not be displayed normally, or the screen went black immediately after prompting no signal, and then prompted no signal, and the screen went black again

1. There is a problem with the MCU, which causes the LCD to be converted between boot and standby.

2. There is a problem with the signal recognition circuit, which makes the line field synchronization signal received by the MCU abnormal, resulting in signal recognition errors and making the MCU issue wrong instructions.

3. There is a problem with the power supply circuit of the display power supply, or the protection circuit is in action.

YesNotebook win7 systemUsers report that when opening certain programs, the computer often flashes their pants and dresses up the screen, and then returns to the desktop. Why does the screen splash? It may be due to over-optimization of the system or the flickering screen phenomenon caused by the accelerator program, so what should we do when we encounter this situation?

Let's take you to learn the specific solution!

Cause 1: The screen splash caused by excessive optimization

Workaround:

1. Click the "Start" menu of win7 system and select the "Run" option;

2. Enter the "regedit" character command in the "Run" dialog box that opens, and press the OK key;

3. In the open registry, Hu Kaizao deletes hkey usershungapptimeout and waittokillapptimeout subkeys in default desktop;

4. Delete the Hkey Current User, Hkey Current User ControlPanel, and Hkey Current User ControlPanel subkeys under Hkey Current User, WaitToKillAppTimeout, and WaitToKillServiceTimeout in Desktop.

5. Just restart the system!

Reason 2: Splash screen caused by accelerator program

Workaround:

Notebook win7 system open some programs appear splash screen two solutions to share with you here,According to the two modifications in the tutorial to modify the registry can effectively solve the win7 system splash screen problem。

Problems with the display itself.

If it is a CRT monitor, click the button above the monitor, find out the degaussing, degaussing to check the problem with the cable: VGA cable or HDMI cable, reconnect or change the power cable, unplug it and reconnect it to turn on the monitor.

First of all, you need to figure out whether to open a fixed program flash, or open any program flash.

If you open a fixed program flash, and there may be a conflict between the program's built-in VGA driver and the driver installed by the system (you can upgrade the native graphics card driver to the latest version);

Or your hardware configuration part does not meet the requirements for the operation of the program (mainly the graphics card or monitor part).

If any program flashes when you open it, please upgrade the native graphics card driver to the latest version and try again, if the problem still exists, please find the fault on the hardware (such as the monitor or graphics card).

It may be that your system has too many programs open at the same time, you try to close it and try again!

It could be a resolution readjustment.
