What is the reason for the screen of the computer?

Drive. One of the most important reasons for the flower screen phenomenon in the computer is the driver problem. Sometimes the screen will appear after replacing the graphics card driver or the driver file is damaged. At this time, you can check the graphics card driver first and reinstall the driver that has been certified by Microsoft WHQL. Temperature.

Graphics card problem: The graphics card may be overheated or damaged, resulting in a flower screen phenomenon. Monitor problems: The monitor may have problems such as aging, damage, poor contact, etc., resulting in the screen display.Connection cable problem: The connection cable may be damaged or poor contact, resulting in poor signal transmission and flower screen on the screen.

The overheating of the core chip of the display card will also cause this kind of display card with a flower screen. The capacitor is limited by the use temperature time. If the fan is not good, it will cause the core chip temperature to be too high.

The main reasons for the computer's screen crash are the following memory problems. Memory will cause the screen, because the integrated motherboard usually integrates the display engine inside the North Bridge chip of the chipset, and uses part of the physical memory to act as video memory. And if the shared memory of the integrated graphics card is too low, it will cause the screen to die.

Computer system startup flower screen Fault phenomenon: Recently, my computer has a flower screen phenomenon every time it starts up, and the refresh rate of the monitor has changed after entering the system.Restart the computer and then enter the system, and the problem disappears again.

What to do with the flower screen after the computer is turned on normally

Dealing method: For problems such as computer flower screen, you can restart the computer to enter the safe mode, change the display resolution to the resolution suitable for the monitor, and then start again It can be restored by moving the computer. If this method doesn't work, you can delete the graphics card driver in safe mode and then reinstall the graphics card driver in normal mode.

You can start up and press F8 to enter the advanced mode. In the "Advanced Mode" interface, select "Safe Mode". After entering the safe mode, uninstall the old driver of the graphics card in the settings manager, then restart the computer to enter the normal system, and then update the graphics card driver again.

Check whether the fan is running normally, refuel the fan, clean up the dust in the chassis, and troubleshoot after solving the heat dissipation problem.

If the display is displayed as soon as it is turned on, first check the heat dissipation problem of the graphics card, touch the temperature of the graphics memory chip with your hand, and check whether the fan of the graphics card stops.

What to do if the computer displays a flower screen when it starts up and enters the system

There is a similar failure in the external display, so you need to consider updating the graphics card driver, Flash plug-in or restoring the system. The software problem cannot be troubleshooted. Replace the CPU test to determine whether the failure is caused by the CPU or the motherboard.

Send the computer to the after-sales service center for inspection and maintenance;Replace the computer graphics card with good quality and compatible with the system; reinstall the computer system, or optimize and upgrade the computer system before use; download anti-virus software to check for computer viruses.

Method 1: Check the hardware. First of all, you can check whether there is a problem with the hardware device, such as the graphics card, memory stick, hard disk, etc. You can unplug these devices, clean the interface and try to plug them in again. If there is still a flower screen phenomenon, you can consider replacing these devices.

Restart the computer: Try to restart the computer to solve the flower screen problem. Sometimes the system has cache problems or driver errors, and restarting can make these problems disappear. Update the graphics card driver: If the graphics card driver of the computer is outdated or damaged, it may also cause a flower screen phenomenon after power-on.

My computer has installed a new system and the screen is not displayed. Dear, what's going on?

Flower screen caused by the increase in the temperature of the computer graphics card. Solution: Check whether the fan is running normally, lubricate the fan, clean up the dust in the chassis, and troubleshoot after solving the heat dissipation problem.

The graphics card driver is incompatible or damaged. Please upgrade the graphics card driver first (download the driver wizard). The temperature of the graphics card is too high or the graphics card is incompatible or damaged. If the temperature is too high-definition, it will be gray. If there is a problem with the fan, replace the cooling fan.

The graphics memory speed is too low: When the graphics memory speed is too low to match the speed of the host, there will also be a flower screen phenomenon. How to deal with it: replace the faster video memory or reduce the speed of the host.

Analysis of the causes of computer blue screen. In general, there are two aspects: software problems, driver loss or error, hardware problems such as memory, network card, loose installation of sound card, etc. In the process of using the computer, blue screen is often encountered. For beginners, it seems like a computer disaster, and they are at a loss.

The computer has a screen before entering the system, but what is the reason why it is normal after entering, and how to solve it?

1,. The video memory speed is too low: When the video memory speed is too low to match the speed of the host, there will also be a flower screen phenomenon. How to deal with it: replace the faster video memory or reduce the speed of the host.

2. The screen of the laptop is mainly due to hardware problems or operating system problems. If it is a hardware problem, you can only go to the after-sales service for repair. If it is a problem with the operating system, I suggest you reinstall the system and try it. After power-on, press F8 to enter the reinstall system mode. Generally, the laptop screen only needs to reinstall the system.

3. According to the situation, there should be something wrong with the screen. The flower screen checks from the following aspects and sets the BIOS to the factory default value.Remove the memory, erase the golden finger with an eraser, clean up the motherboard memory slot, and plug it in; increase the virtual memory setting, and set the virtual memory to a partition with a large space outside the C disk.

4. The failure of the graphics card driver or incompatibility with the operating system will also cause the screen to flash. The solution is to reinstall or upgrade the graphics card driver. Download and install "Driver Life 6". First uninstall the original graphics card driver and reinstall it. "Drive Life 6" can automatically identify the matching graphics card driver.

5. The solution is as follows: you can press F8 to enter the advanced mode. In the "Advanced Mode" interface, select "Safe Mode". After entering the safe mode, uninstall the old driver of the graphics card in the settings manager, then restart the computer to enter the normal system, and then update the graphics card driver again.

6. It means that you have installed something inappropriate, uninstall all the inappropriate things downloaded before, or restore the system or reinstall it).

What to do if the computer is turned on as soon as it is turned on

Check whether the power supply is normal and stable; 2. Whether the machine has been upgraded the memory, unplug the memory and use alcohol and eraser to wipe the memory gold finger.
