The laptop has not been used for a long time, why is the screen blurred when connected to the wirele

Graphics card screen is a relatively common display failure, most of the graphics card screen failure is 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, a miscellaneous GeForce of mine before

The laptop has not been used for a long time, and now the operation has a blurred screen.

Hello, the laptop has not been used for a long time, and then the problem of the screen appears when it is turned on, there are two reasons for this situation, the first reason is that there is a problem with the graphics card screen connection cable of the notebook computer, because the laptop is not used for a long time, the display connection cable has always been folded, and it is possible to tear the connection cable when it is opened again. The second reason is the problem of the graphics card, if the electronic product is not used for a long time, the electronic components inside will be damp and damaged.

Laptop intermittent screen is a very common problem, you may encounter it when using a computer, what should we do at this time?

1.Check for computer hardware problems: There may be computer hardware problems, such as screens, graphics cards, etc., which require you to go to a professional computer repair shop for overhaul and replacement parts.

2.Replace the data cable: Sometimes the unstable screen may be due to a problem with the data cable, you can replace the data cable to try to solve the problem.

3.Upgrade the graphics driver: If it's a problem with the graphics driver, you can try upgrading the graphics driver, which may fix some screen blur issues.

4.Check the computer system: If the computer system is abnormal, it may also lead to a blurred screen, so you can conduct a system check to clean up the system garbage and optimize the system operation to see if it can solve the problem.

5.Excessive temperature: Too high computer temperature is also a cause of the problem of blurred screen, you can clean up the dust inside the computer, and try to achieve good ventilation and heat dissipation.

In short, the problem of intermittent screen of laptops needs us to analyze from many aspects, try different methods to solve it, if the above methods do not solve the problem, it is recommended to go to a professional repair shop for maintenance. At the same time, we should also pay attention to the daily maintenance of the computer, as much as possible to achieve cleaning, ventilation and heat dissipation, to prevent the occurrence of the problem of the screen problem.

Computer screen is a relatively common display failure, most of the computer screen failure is caused by the graphics card itself, may be the display and graphics card loose wire, graphics card damage or overclocking, other possible reasons are caused by the computer temperature is too high or too much dust. The first thing to check when the screen is blurred is the graphics card driver, according to the principle of soft first and then hard. The following is the solution to the blurred screen of the laptop screen that I have compiled for you, welcome to read, I hope you can like it.

The solution to the problem of a blurred screen on the laptop screen is 1. Driver problems mostly occur after changing the driver version of the graphics card, and may also be caused by the damage of the driver file. The solution is very simple, reinstall the driver that has passed the Microsoft WHQL certification, and there is no need to blindly seek new versions.

2. The heat dissipation effect of the main control chip of the graphics card is poor, not only because of the graphics card, but also because the chipset temperature of the processor, memory and even the motherboard is too high. 3. Video memory damage, when the video memory is damaged, there will be a phenomenon of blurred screen and confused characters when the system starts.

Solution: The video memory chip must be replaced. Note that some video memory is integrated into the graphics card chip, so the graphics card chip must be replaced.

4. When the video memory speed is too low to match the speed of the host, it will also produce a blurred screen. 5. The memory module problem may be caused by the damage of the memory module, which can be wiped by wiping.

Solution to the problem of the blurred screen:

1. Due to poor heat dissipation of the case, the screen caused by the temperature of the graphics card rises.

The solution is to eliminate heat dissipation issues.

2. The solution caused by the graphics card or monitor does not support 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, and 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) The system is overheating, including the CPU temperature is too high and the graphics card chip is too hot. You can install cooling fans in the appropriate locations in the case, or place the case in a well-ventilated area.

Analysis: Abnormal display of display colors may be caused by poor contact between memory or graphics card and cables, or poor heat dissipation.

Processing: Generally, it can be recovered by restarting, if it is invalid, the operation is as follows:

1.Shut down (if short press the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don't be weak).

The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.Enhance the heat dissipation inside the case and the environment in which it is used, and reduce the time spent playing large games.

1. The driver of the network card is incorrect, because the use of compatible drivers will lead to software conflicts and crashes, go to the official website to install the driver now, uninstall the network card before installation, and restart the computer to load the driver after the driver is installed.

2. There is a problem with the hardware of the network card, when it is used for a period of time, it will not work normally because of heating, resulting in an error in the bus and crashing, in this case, it will be shielded in the BIOS, and then the external wireless network card can be used.

Supplementary reasons: 1. A computer crashes frequently, and it will crash even when entering the BIOS settings.

2. Fault analysis and processing: If a crash occurs when entering the BIOS, it can be preliminarily judged that there is a problem with the motherboard or CPU, generally due to the problem with the cache of the CPU, then enter the BIOS settings and prohibit the cache to solve the problem smoothly.

3. If the fault cannot be solved, then the only way is to replace the CPU; If the temperature is high, it is caused by poor heat dissipation of the motherboard, and you only need to replace the high-power fan to eliminate the crash.

Solution: 1. Whether there are any added or external hardware devices, and if there are any removal of these devices, see if it is solved;

2. Boot up and press F8 to enter the safe mode to use the machine to see if there will be a crash, if there is a format of the hard disk after saving important files to install the system to see if it can be solved, if not, you can try to do a full check to kill the virus and close the unwanted boot startup items to see if it can be solved, if it still can't be solved, you can try to reinstall the operating system;

3. Whether this fault occurs when the temperature of the laptop is high, if so, you can try to clean up the dust of the machine to see if it can be solved.
