The computer screen flashes with white horizontal lines which flash quickly and sometimes goes bla

It's not memory, it's a problem with the graphics card.

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.

Dear, the situation of a flashing white screen on the computer can usually be due to the following reasons:1Graphics card driver issues:

There's a problem with the graphics driver connected to your computer monitor, causing the screen to flash white. You can try to uninstall the graphics driver and reinstall or upgrade the graphics driver. 2.

Display problems: There may be problems with the wiring or components of the display, you can check whether the wiring is loose or replace other display devices for testing. 3.

Operating system issues: It could be that the operating system's files are infected or corrupted, or it could be an operating system upgrade that causes compatibility or setup issues. You can try booting your computer in safe mode, blinding yourself or reinstalling the operating system.

4.Virus and Trojan infection: Computer infected with viruses, Trojans and other malware may also cause the screen to flicker with a white screen, and you can use antivirus software to fully disinfect the virus.

5.Hardware failure: Failure of hardware devices such as computer motherboards, memory, etc., may also cause the screen to flicker with a white screen.

You can try cleaning the dust inside the wheel cavity or replacing the faulty hardware. If you are unsure of the specific reason, it is recommended that you go to a professional computer repair shop for an inspection or consult the brand after-sales service center to find the best solution.

<> computer screen flashes and goes black quickly: It may be a problem with software compatibility, given that users are playing games that occur frequently, so it is important to check whether the game software and the graphics card driver are incompatible, and you can update the graphics card driver. It is also possible that the connection between the main unit and the monitor is not in good contact.

The connector of the cable can be removed for simple cleaning.

This answer is available for computer brands such as ASUS N56Xi323VZ-SL, Dell Inspiron 15 (5559) INS15U-3548, etc.

1. The screen will be black if the monitor is not in good contact, you remove the interface behind the monitor and clean it up, and try it again, be careful not to connect the interface in reverse. If the contact is okay and it doesn't work, it's best to try a different monitor to determine if there is a problem with the monitor.

2. See if there is a problem with the power box in the host computer that causes the computer to stop working due to power failure. Unscrew the case screws with a screwdriver and remove the lid to reveal the power box. Use tweezers to connect the black and green wires in the 24 pins of the power supply, see if the fan of the power supply is running normally, and eliminate the power supply fault if the fan does not rotate or the speed is very slow, most likely the power supply is faulty, change the power supply.

3. Whether the 4-pin plug of the power supply is forgotten to be plugged in, this situation is mostly seen after the computer is cleaned. Forgot to insert this 4 pin, the computer black screen is not working properly.

4. The memory module will be black if the contact is not good, if the memory module is faulty, there will generally be a beep alarm sound, if there is an alarm sound, you open the chassis and take out the memory module to clean it with anhydrous alcohol or an eraser, re-plug it once or try to change the slot, and be careful not to insert the memory module in reverse.

5. Check the failure of the hard disk, the failure of the general hard disk will have English prompts on the screen, such as "the hard disk cannot be found", "the system cannot read", etc. If the connection line is faulty, a different line will do. Such as:

a disk read error occurred press ctrl+alt+del to restart”。

6. The graphics card will be black if the contact is not good. You remove the graphics card, clean it up, and try it back. If the contact is okay, it is best to ask someone to borrow one and try another graphics card to determine if it is a graphics card problem.
