There may be several possibilities for this problem. First of all, when the machine is running large programs, the CPU usage may be too high, causing the performance to be unable to keep up, resulting in lagging problems. Secondly, there may be a problem with the graphics card driver. In addition, it is possible that the silent upgrade or installation of third-party software causes system resources to be occupied, resulting in lagging. For example, an update to your antivirus software may cause this.
Hurry up and clean the dust in the case, check whether the graphics card and sound card are loose and whether the sockets are in good contact to prevent the fault from expanding. There may be a problem with the anti-virus software. When the anti-virus software automatically kills viruses, it will occupy a high amount of CPU, causing a suspended animation. After you turn on the computer, end the anti-virus and firewall processes, and then take a look. It may be a problem with bad sectors on the hard disk. When the computer is running at high speed, if the power is suddenly cut off, it will cause great damage to the hard disk, and even Bad sectors will happen! Clear enough free space on the C drive, and right-click on "My Computer"-Properties-Advanced-Performance-Settings-Advanced-Virtual Memory-Change-Custom Size, increase the virtual memory appropriately, and it will take effect after restarting the computer. The problem may occur in the computer's CPU or graphics card. It may be that your CPU does not dissipate enough heat. First, consider whether yours is a discrete graphics card. If it is not a discrete graphics card, you may experience lag when playing 3D. That is very normal.
After the card is stuck, it will become persistent. The card will be stuck again after a while. The time is about 30 seconds to 2 minutes.
The graphics card or driver may be the problem: replug, clean, and check if the fan is running properly. Update the driver using the driver wizard. If the problem persists, it can be replaced free of charge during the warranty period.
A friend of mine also encountered a similar problem. There would be a delay of one or two minutes when typing, and he would often shut down his phone unconsciously. After testing, it was found that there was a problem with the hard disk, probably because it had been used for too long.
It is recommended that you do some cleaning work first, especially the fan and cooling system to ensure that there are no overheating problems. Then, clean the dust inside the host, including components such as memory modules and graphics cards. At the same time, make sure there is enough space on the C drive to clean up some unnecessary files. In addition, you can right-click on "My Computer", select Properties, then enter Advanced Options, find Performance Settings, then enter Advanced Options, find Virtual Memory Settings, click Change, select Custom Size, and increase the virtual memory appropriately. size. Finally, restart your computer for the changes to take effect.
If it still doesn’t work, reinstall the system
If it still doesn’t work, it’s a hard drive problem! ~
1. The reasons why the computer screen freezes are as follows:
1. Caused by Trojan virus
It is normal for viruses to cause computer screen freezes. Thousands of system loading points are present, affecting the normal operation of system files and causing screen freezes.
2. Too many startup items
Many people download a lot of software when using computers. Many software will come with some programs. Too many startup items will occupy memory, so they should be cleaned up in time.
3. Too much garbage in the computer system
Computer garbage includes the window temporary directory, window update patch directory, browser cache directory, etc. These can generally be found when testing the computer and must be cleaned up in time.
4. Computer hardware configuration issues
This situation is more likely to occur when running multiple software at the same time. Although sometimes everything is normal when running many software at the same time, sometimes it suddenly crashes inexplicably. After restarting, it is normal again when running these applications. Well, in fact, many of these failures are just fake crashes.
The reason is mostly a conflict in memory resources - application software runs in memory, but some application software will use the same memory address with another software at the same time due to design reasons, and conflicts will occur. .
5. Too much computer dust
After a new computer has been used in an average city in my country for about a year, there will be a lot of dust inside it. If it enters the slot of a certain board card, it may cause poor contact of the board card and cause a crash or crash. Other faults, and often crashes for no reason.
Extended information:
Solutions to computer screen freezes:
1. Start Task Manager
Choose to start the Task Manager to see which processes are taking up computer resources. If you don't know whether some processes are viruses, etc., you can search for relevant information about the process and choose to end the process. Check the CPU. The process that takes up the most CPU will appear on the first line. Check whether the process is useful. If it is useless software, end the process.
2. Exclude incompatible software
Check how many anti-virus software or security software are installed. If two are installed, close one of them and let only one anti-virus software run automatically after startup. Anti-virus software may cause compatibility issues due to multiple sessions. Make the computer laggy.
3. Delete desktop icons
It is recommended to delete some redundant icons on the desktop and do not place too many icons on the desktop. This will cause the program or software to start very slowly when running.
4. Upgrade computer configuration
If none of the above methods can solve the problem, it may only be a problem with low computer configuration. After upgrading the computer, the parts that are often upgraded are the CPU and memory. The size of the hard disk will not affect the speed of the computer. You can also upgrade the fan to achieve cooling purposes.
1) When your computer freezes or freezes, what are you doing on the computer? Can you tell me? I will answer you more accurately based on what you said.
Please describe the performance of your computer before the screen freezes or crashes, and your operations in more detail. It may be these operations that caused the screen freezes or crashes. If you have any questions, please ask me (I will try again based on the information you provided) answer you).
Generally, screen freezes or crashes are caused by incorrect operations. Remember not to perform operations that are likely to cause screen freezes or crashes. Do not operate the computer at full load. That is, when you are playing games, watching videos, downloading, or browsing web pages, it is most likely to restart, crash, or blue screen when doing other operations. Therefore, do not operate the computer while playing games, watching videos, downloading, or browsing web pages. Working on something else.
No matter what you are doing, as soon as there is any sign of lag, stop the operation at hand and exit the test. If it still happens, stop playing or watching.
In terms of hardware, if the memory module is small, add a memory module. If the temperature of the CPU and other hardware is too high or the hard disk has bad sectors, it may be caused by inappropriate hardware.
2) If it is related to the hardware, one is that your memory is low, the temperature of the CPU and other hardware is gray, and there is a problem with the hard disk, use software to fix it. In terms of software, uninstall the things you downloaded before the accident, and download the Win Cleanup Assistant to check and kill them. Trojans, system restore or reinstallation, do not operate at full capacity if there are any.
