The biggest fear when buying a laptop is that something will go wrong. Once something goes wrong, you won’t know how to fix it. So what’s going on with laptop screen flickering? Here we’ll introduce you to the causes of laptop screen flickering. Come and take a look!

Reasons why the laptop screen flickers:

First, the cable is not connected properly or is loose.

The second is that the lamp inside the display screen is broken or has poor contact. First disassemble the machine and check whether the wiring is normal. If it is normal, it means there is a problem with the lamp, which needs to be repaired by a professional repair center. of.

At the same time, you can also check the following aspects:

Excessive temperature inside the chassis, graphics card, memory, and power supply will cause blue screens and crashes.

1: The memory stick is oxidized due to metal contact, or two memory sticks are used, one of which is damaged or incompatible. If the metal in contact with the independent graphics card is oxidized, unplug the memory and graphics card, clean the metal in contact with it (gold fingers) and replace the damaged memory module. Clean the graphics card radiator and fan dust. If the fan is damaged, replace it.

　2: Motherboard: After a certain period of use, a lot of dust accumulates on the motherboard. Electrolytic capacitors leak, bulge, and fail. Thoroughly remove dust from the motherboard. The focus is on the memory slot, graphics card slot, and around the CPU. Replace the capacitor or send it for repair.

3: CPU. The CPU is the supreme commander of the computer. If there is a problem, such as excessive temperature, unstable voltage, or excessive overclocking, the CPU will automatically protect itself. The computer will be paralyzed, so there will be a blue screen, crash, ---- clean the CPU radiator and fan dust. Replace the thermal grease under the radiator and restore the CPU default frequency.

4: Power supply, power supply is the driving force for the normal operation of the computer. After a certain period of use, due to accumulated dust, capacitor failure, fan dust, and reduced speed, poor heat dissipation and reduced output power may also cause crashes, restarts, and blue screens—repair or replace the power supply.

5: The system drivers installed using the GHOST version are often not installed very accurately, especially the sound card, network card, graphics card and motherboard chipset drivers. ----Solution: Install the installation CD that comes with the motherboard, download EVEREST to check the exact model of each hardware, download the driver wizard, and then install the correct driver.
