Why does the computer appear like a mosaic in any window after being open for a long time and then f

It should be a bad heat dissipation,Open the case,Clean up the CPU,Dust on the graphics card fan and power supply,If it doesn't work,It's necessary to replace the CPU fan with a little more power,Recently, there are a lot of problems like this,It's all when the machine was configured before,The fan power is small,In addition to the current online game is quite big,The computer has been running for a long time,Useless system garbage,There is more dust,Running large online games, etc.,CPU occupies more,Can't quickly dissipate heat,Resulting in high CPU temperature,Cause the computer to respond slowly, Crash.

Hello,,I'm glad to answer for you,I hope it will help you There are many reasons why the computer frequently crashes and restarts and shuts down,1Caused by viruses, it is recommended to try the full antivirus, 2 There is an error in the system file, it is recommended to reinstall the system 3 There is a conflict between software and hardware or some software is incompatible with the system Reinstall the system or driver, 4CPU temperature is too high or other hardware temperature is too high to clean up the dust under the chassis Change to a larger fan Pay attention to heat dissipation This is very important The temperature is too high and will also cause the system to run too slowly 5 "crashes" caused by the exhaustion of resources in the subsystem of the machine, such as often CPU usage 100/100, You can open some programs or replace the CPU to increase the memory as little as possible 6 Caused by pirated software Please delete 7 The hard disk has bad sectors, fix it and try 8 The crash caused by the incorrect BIOS setting or the unsuccessful overclocking can take off the motherboard battery and discharge it Let the BIOS settings be restored to the default value 9 Crash caused by other reasons, such as unstable voltage The memory quality is not up to par The disc reading ability of the optical drive is reduced, the quality of the floppy disk is poor, etc. 10 Caused by the operator's misoperation --fly Ōfei answer--- plagiarism is shameful--- plagiarism must be reported--- thank you--- I wish you happiness and health.

One is to check the temperature of your CPU. See if it's higher. The other thing is to reinstall the graphics card driver.

If it's not that the computer is too slow, or the graphics card driver is not installed, find a matching driver and reinstall it.

Check the monitor and graphics card, there should be a problem with the graphics card.

The monitor data cable is loose, or the graphics card is faulty, or the monitor is faulty.

1. Please check the connection of the monitor first to see if it is firm or loose?

2. Check if the graphics card is faulty? (You can run the game and then test it).

It should be that the graphics card is not working,

There's a simple way to do this, smash the computer and replace it with a new one.

Computer crashes are often caused by software

1.Virus infection: Viruses can drastically reduce the productivity of a computer, causing frequent crashes.

At this time, we need to use anti-virus software such as Kingsoft Antivirus (free for life), KV3000 Rising (charged), etc. to comprehensively check and eliminate viruses, and upgrade antivirus software regularly.

Improper settings. 3.Accidental deletion (or error) of system files

4.Initialize the file found corrupted.

5.Dynamic Link Library files (DLLs) are missing.

6. The remaining space of the hard disk is too little or there are too many fragments (it is recommended to use the system cleaning function of Kingsoft Toxicity, which is very convenient to solve the system fragmentation).

,1G memory,FX5200 graphics card can run,It may be a problem with the graphics card driver,You go to the driver home to change the driver to try。 It may also be a heat dissipation problem, and the temperature is too high after class, and it will also crash with a blue screen.

In addition, the virtual machine group is on the product**, which is super cheap.

If the graphics card is broken, it is estimated that there is a problem with the interface of the graphics card or the connector is loose.

If there is a problem with the graphics card or graphics card driver, it is recommended to reinstall the graphics card driver or replace the graphics card.

The problem with Dragon Nest itself, only nvidia's graphics cards will do this... So do I ... Now I'm planning to go to the Internet café with my classmate when he returns to school, and my Internet is about to expire anyway.

It's usually too hot, so take it to the computer store and ask someone else to get it for you.

Is it like this as soon as you turn it on, or is it just like running some programs? If it's like this when it's booted, it's undoubtedly a problem with the graphics card.,One may be bad contact.,Another possibility is that there's a problem with the graphics card itself.。

This is a typical graphics card screen, disassemble the case and touch the graphics card backplane with your hand, feel whether the graphics card temperature is hot. Usually this situation is caused by the poor quality of the hardware of the graphics card. If it is not hot, you can see if the screen will be blurred after installing and restarting from the Internet, if not, you need to reinstall the system, which may be caused by the loss of system files.

If you are hot, go directly to the seller of your computer to replace the graphics card (the warranty period of the graphics card is usually one year, and in a few cases, it is two years).

Let's see if the cable between the monitor and the graphics card is loose!

Then check under which the graphics card is not loose

If it's neither, I guess you can change the monitor!

There is only one possibility in this situation, there is a problem with the graphics card, and I think of it from my years of experience.
