Why does the computer monitor keep flashing?

The internal temperature of the case is too high, the graphics card, the memory, the power supply - will cause a blue screen, crash, the following is a little experience that individuals have summarized in the repair process, you can take a look at the control check treatment. --You can check, clean, replace, memory, hard disk data cable first.

1;The memory module oxidizes when it touches some metal, or two memory modules are used, and one of them is damaged or incompatible. The discrete graphics card is oxidized when it touches the metal, unplugs the memory, the graphics card, cleans the metal in contact with the metal (gold finger) and replaces the damaged memory module. Remove dust from the graphics card cooler and fan.

If the fan is damaged, replace it.

2: Motherboard: After a certain period of use, a large amount of dust accumulates on the motherboard.

Electrolytic capacitors leak, bulge, and fail. Dust the motherboard thoroughly. The focus is on memory slots, graphics card slots, around the CPU.

Replace the capacitor or send it for repair.

3: It is the supreme commander of the computer, if there is a problem, such as too high temperature, unstable voltage, excessive overclocking, then the CPU will automatically protect itself. The computer will be paralyzed, so there will be a blue screen, freeze、-- clean the CPU cooler, fan dust.

Replace the thermal grease under the heatsink and restore the default CPU 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 the accumulated dust, capacitor failure, fan dust, and speed drop, resulting in poor heat dissipation and output power drop, it will also cause crash, restart, blue screen--- repair or replacement of the power supply.

5 System drivers installed with the ghost version are often not installed very accurately, especially for sound cards, network cards, graphics cards, and motherboard chipset drivers. --Solution, install the motherboard that comes with the installation CD, **most check the exact model of each hardware, **driver wizard, and then install the correct driver.

6: There is a problem with the hard disk or the hard disk data cable, the hard disk increases with the use time, and the abnormal shutdown during use causes logical or physical bad sectors. Logical bad sectors can be repaired using dedicated software.

Physical bad sectors can only be replaced with hard drives. If the data cable is used for too long, it can also be problematic, and it can be eliminated by the replacement method, (the phenomenon of data cable failure is very similar to that of memory failure).

The above is only for desktops) The above is my experience summarized in the actual maintenance process.

Check the data cable (blue headband screw), the data cable is not tightened and the screen will flash. You try it.

It could be a problem with the system.

Summary. Graphics card driver or graphics card by issue. The graphics card is the core of the computer graphics display, when the display is not normal, then it may be related to the graphics card, in the case of the display flashing screen, you may wish to update the graphics card driver first, it is best to update to the latest version to try.

If it really doesn't work, then consider whether there is a problem with the graphics card.

4. Display problems. If there is a problem with the monitor itself, it can also cause the computer monitor to flicker.

What's going on with my computer monitor flashing all the time?

It may be the interference of external signals that causes the screen to flicker, or it may be that there is a problem with the data cable connected to the display and graphics card, which needs to be replaced in time. Or the screen refresh rate is too low, you need to change the refresh rate: 1. Right-click in the blank area of the computer desktop and select Display Settings.

2. Swipe down to find the advanced display settings and change the refresh rate to a higher configuration.

If it doesn't work, it is recommended to go to after-sales maintenance.

If it helps, give you a like, thank you.

The computer screen suddenly keeps flashing.

Can't you receive the message?

It's hard to do it all the time.

Then find someone to repair it.
