How do I fix my laggy computer?

What should I do if my computer is very stuck and slow?

Hello, the main root causes of computer card mainly include the following situations:

When the computer freezes, we can check whether the memory is insufficient. Sometimes, some programs may take up too much memory, causing your computer's performance to slow down. For example, some large software such as Office, Photoshop, etc. may occupy more memory. In addition, running QQ for a long time may also cause excessive memory usage, causing computer freezes.

2. Some processes occupy too much CPU. Some software has bugs or other problems. If it runs for a long time, it will occupy too much CPU.

Excessive junk in the computer system can cause lag, such as browser cache, temporary files and invalid registry entries.

4. Trojan viruses scan and collect information in the background, which may occupy too many system resources and cause computer lag.

5. With the development of time, software has higher and higher system requirements, which causes the computer to have lagging problems when running large-scale software and games.

6. Address the above problems one by one to solve the computer card situation.

It is recommended to check for Trojans first and download Trojan killing software to fully scan and kill the system to eliminate the possibility of Trojans causing computer freezes.

If the computer freezes, it may be due to insufficient memory. You can optimize the memory or close processes that take up too much memory. Use software optimization to shut down the process when it is ineffective to save memory.

3. Close the process and solve the problem of computer card

4. Next, check whether the CPU usage is too high. You can press CTRL ALT DEL to open the task manager to see which processes in the system currently have the highest CPU usage. If so, you can right-click the corresponding process. Click to close the process.

5. If there are too many junk files in the system, you can use some system junk cleaning tools and C drive cleaning tools to clean and optimize the system.

6. What to do with computer cards? If the computer card problem cannot be solved after the above exclusions, please check whether the hardware is outdated. You can solve the computer card problem by upgrading the hardware.

What to do if the computer is running very lag

1 Regularly, use software such as Master Lu to measure various temperatures of the computer. If the temperature is too high and it will cause the computer to run slowly, it may be that the internal fan is broken or something. Clean the dust in the computer. Desktop After turning off the machine, open the case and use a hair dryer to blow cold air.

2 Use 360 ​​Defender, Kingsoft Defender and other tools to clean up system junk and temporary files (ie cache) generated by surfing the Internet, and check for malware.

3 The computer configuration is poor, try to set the virtual memory as large as possible, (xp) right-click My Computer Properties Advanced Performance... There Settings Advanced Change

In customization, set it to 2000 - 4000

(win7) Computer-Properties-Advanced System Settings-Performance Settings-"Advanced" tab-Virtual Memory-Change-Select the drive c drive to be set, select the system management size or select a custom size as needed-Settings- Sure.

4 Install anti-virus software that takes up a small amount of resources, such as nod32, or only install an auxiliary anti-virus software.

5 Try to set the IP to a static IP, which can reduce the startup time of the computer and the reflection time after entering the desktop. (cqjiangyong concluded: Many people cannot move their computers for the first few minutes after they are turned on because of this reason)

6 Don’t put too many files and icons on the computer desktop, which will slow down the computer’s response. Try not to install software on the C drive.

7 Close some startup programs. Start-Run-enter msconfig-OK-click "Start"-Start in the "System Configuration Utility" window. Except for the input method (Ctfmon) and anti-virus software, general programs can be turned off. You can also use software such as 360 to intelligently optimize boot acceleration.

8 It is recommended to install only one main anti-virus software. Installing multiple anti-virus software will occupy computer resources and make the computer slower.

9 Defragment the disk regularly. Open the drive in My Computer that you want to defragment - Properties - Tools - Select the disk to be defragmented and open the "Disk Defragmenter" window - Analysis - Defragmentation - the system will start. tidy.

10 Install computer optimization software such as Optimization Master or Super Rabbit. With optimization, the computer will be much faster! !

11 The current system also occupies a relatively large amount of memory. If necessary, adding more memory will make it much faster.

12 If the computer hard disk is used for a long time, it will also make the computer slow down. Repartitioning and installing can repair the logical corruption and make the computer faster. The physical read and write speed of the hard disk is slow, so you can only replace it with a better one! ! !

What to do if the computer is too stuck

The computer is too slow and stuck. It is likely that there is too much computer garbage and insufficient running memory. It may also be that the temperature of the computer hardware is too high, there is too much dust on the chassis (causing high temperature of the desktop hardware, etc.), or the hardware configuration is too low. , even poisoning!

1. There are too many open programs that occupy a lot of resources: Click the accelerator ball to accelerate, and close the programs that occupy too many resources (for example: do not watch videos, but there are video processes, etc.): Dealing with too many junk files on the computer: Use 360 ​​Security Guard to clean: Open 360 Security Guard → Computer Cleanup → One-click cleaning, clean garbage, clean software, clean plug-ins, and clean traces. This can clean up a lot of garbage.

2. Insufficient running memory 1. If there is insufficient running memory, set a larger virtual memory:

(1) Win7 system: Steps: Right-click "My Computer" on the desktop → Properties → Advanced System Settings → Advanced → Find "Settings" of "Performance" → Advanced → Virtual Memory: Change.

(2)XP system: Steps: Right-click "My Computer" on the desktop → Advanced → Click: "Settings" in "Performance" → Click: "Advanced" in the "Performance Options" dialog box → Virtual Memory: changed. 2. If the memory is insufficient, you can install additional memory modules, which need to be purchased at the store (it is recommended to take the host to a computer store to install compatible memory modules).

3. Caused by excessive temperature 1. Excessive temperature of computer hardware can also cause computer card, delay, crash, blue screen, automatic shutdown, or automatic restart. You can download a temperature measurement tool to test the computer hardware: the more commonly used tool is: Master Lu. You can search and download "Master Lu" in "360 Software Manager" as shown in Figure 9: If the temperature of a certain hardware is found to be too high, please first Clean the dust, or deal with it according to the actual situation. If you don't know how to deal with it, you can take it to the computer store for treatment: for example, if the CPU temperature is too high, the silicone grease may have dried (add thermal grease: 1 to 2 yuan per small package), or the fan speed is slow. (clean the fan dust or replace the fan); the graphics card temperature is too high, the motherboard has too much dust, etc. There are many reasons... handle it according to the actual situation.

4. Computer Poisoning Computer poisoning and damage to system files can also cause problems such as slow operation or even crash.

1. Use 360 ​​Security Guard → Trojan detection → Full screen scanning and detection;

2. Use 360 ​​Security Guard → System Repair → General Repair;

3. Use 360 ​​antivirus → full scan;

4. Use 360 ​​System First Aid Kit → System First Aid → Scan (use with caution).

5. Reinstall or restore the system (use with caution) Restoring the system or reinstalling the system will format the C drive, causing data loss on your C drive. Please back up important data on the C drive and desktop to other drives before operating ( Such as: D, E, F), and then use 360’s “System Reinstallation” function to reinstall the system: Open 360 Security Guard → System Repair → System Reinstallation.

6. If your computer configuration is too low, please upgrade your computer’s hardware.

Why is the computer so stuck?

Hello.

Computer often freezes

1. In the task manager (ctrl alt delete), select performance and see which programs take up too much memory when stuck, the CPU usage is too high, and there is too much memory. If there is too much memory, check online to find out what process it is. When it's over, the program ends. The CPU is too high, try changing the operating system. You can also check what errors the system frequently reports in the event viewer to see if you can find the problem.

2. For W7 system, you can download W7 Optimization Master and optimize it.

3. W7: Start-Run (enter msconfig)-Enter-Boot---Advanced Options---Check "Number of Processors", select the maximum number of cores--Check "Maximum Memory"-- Sure. Return to the system configuration window - start, keep the anti-virus software and input method, and disable everything else.

4. Use Kingsoft or 360 Guard to turn on startup acceleration in the optimized system and close some processes that you do not need to start at startup.

5. Perform disk defragmentation and disk cleanup. Note: W7 cannot compress the C drive to increase space, otherwise it will not start.

6. If it still doesn’t work, reinstall the system
