The computer has a blurred screen, rebooting and returning to normal, what s going on

Screen is a common display failure, most of the computer screen failures are caused by the graphics card itself, the following solutions may be helpful to you.

If the screen is blurred as soon as the display is turned on, first check the heat dissipation of the graphics card, touch the temperature of the graphics memory chip with your hand, and check whether the fan of the graphics card is stopped. Then look at the AGP slot on the motherboard to see if there is any dust, check whether the gold finger of the graphics card is oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part. If there is a problem with heat dissipation, change the fan or install a heatsink on the video memory.

Or go into the BIOS and see if the voltage of the AGP is stable nearby.

If you are playing games and doing 3D, then you can try to change the graphics card driver to try it after eliminating the heat dissipation problem, because it may be caused by the incompatibility of the graphics card driver with the program itself or the bug in the driver.

If the graphics card is still blank after the above methods, you can try to flash the BIOS of the graphics card and go to the home page of the graphics card manufacturer to see if there is an updated BIOS**. For some miscellaneous graphics cards, you can try flashing your graphics card with the BIOS of a major manufacturer. Be warned, though, that flashing the BIOS is risky.

Streaks on the computer screen are extremely common faults, there are many reasons, there are hardware reasons such as external force hitting the screen to damage the screen, this situation can only be sent for repair, but if it is caused by improper system settings, we can solve it by ourselves.

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

1) External interference, such as electric sparks 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.

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

3.Conflict between the graphics card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and there is no response to random keystrokes, similar to a crash, processing method: enter modec080 at this time to be solved.

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

5.The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the computer screen will also be blurred.

6.Video memory corruption: When the video memory is damaged, there will be a blurred screen when the system boots up.

7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.

Causes and solutions for computer screen blurring:

1. The screen is blurred due to the increase in the temperature of the computer graphics card.

Solution: Check whether the fan is running normally, add lubricating oil to the fan, clean up the dust in the chassis, and solve the heat dissipation problem to eliminate the fault.

2. The solution caused by the graphics card or monitor not supporting high resolution:

1) Restart the computer, press the F8 key continuously, pop up the advanced boot menu, select enter to enter the "Safe Mode" to log in to the system, then enter the display settings under Windows, select the 16-color state, click the "Apply" button, click the "OK" button;

2) Restart the computer, in Windows normal mode, enter the device manager, delete the graphics card driver, and restart the computer;

3) The graphics card is loose, and unplugging the graphics card and reinserting it after shutting down usually solves the problem;

4) If the system is overheating, including the CPU temperature is too high and the graphics card chip temperature is too high, you can install a cooling fan at the corresponding position in the case, or put the case in a well-ventilated area.

Summary. Hello, it's good to restart the computer with a blurred screen, and the reasons are as follows...Excessive hardware temperature can also cause the screen to flicker, such as CPU, graphics card, motherboard, memory, etc., and you also need to check the fan and heatsink.

You can turn it off and then wait for the heat to dissipate, then restart to see if the screen will flicker. 3.If the graphics card is running out of power, the screen will be blurry.

You can disconnect your sound card, optical drive, and other hardware, and then judge after lightening your computer's load.

It's good to restart the computer with a blurred screen, what's going on.

I'm sorry I don't understand, but can you elaborate on that?
