What is the reason for the computer running slow?

Hello

The following is my compilation of computer optimization, computer acceleration methods, please refer to.

1 Regular, clean up the dust in the computer, desktop after the shutdown open the chassis, with a hair dryer, cold air blowing, this is not necessary.

2 Usually use 360 Defender, Kingsoft Defender and other tools to clean up the system garbage and temporary files generated by the Internet (ie cache), check and kill malware.

3 computer configuration is poor, try to set the virtual memory larger, (xp) right-click on my computer Properties Advanced Performance ...... there Settings Advanced Change

In the customization there Set to 2000 - 4000

(win7) Computer - Properties - Advanced System Settings - Performance Settings - Advanced tab - Virtual Memory - Change - Select the drive you want to set to disk c, select the system management size or select a custom size as needed - Set - OK.

4 Antivirus software to install a kind of small resources, such as nod32, or only install a secondary antivirus software.

5 Try to set the ip to static ip, you can reduce the computer boot time and enter the desktop reflection time. (cqjiangyong summary: many people can not move the first few minutes after the computer is on this reason)

6 computer desktop do not put too many files and icons, it will make the computer response slower, the software as far as possible do not install in the c disk.

7 Close some startup programs. Start - Run - enter msconfig - OK - in the "System Configuration Utility" window, select "Startup" - startup, in addition to the input method (Ctfmon), antivirus software, the general program can be turned off. You can turn off all programs except input method (Ctfmon) and antivirus software. You can also use 360 and other software to intelligently optimize boot speed.

8 It is recommended to install only one main antivirus program, installing more than one will take up computer resources and make the computer slower.

9 regularly on the finishing disk fragmentation, open my computer to organize the disk fragmentation of the drive - Properties - Tools - select the finishing disk to open the "Disk Defragmenter" window - Analyze - defragmentation - the system will start. Analysis - defragmentation - the system that begins to organize.

10 Install a computer optimization software such as Optimizer or Super Rabbit to optimize the computer will be much faster!

11 Nowadays, the system takes up a lot of memory, so if you need to add more memory, it will be much faster.

12 computer hard disk with a long time, will also make the computer slower, repartitioning and installation can repair the logic of bad, the computer will also be faster, the hard disk physical read and write speed is slow, can only be replaced with a good point!

I hope to help you ！！！！

Don't understand hi me ！！！！

Please step on the best it ！！！！

Why is the computer broadband good but the download speed is very slow

You try to use the speed measurement software, general antivirus software guards come with this function, whether your 8M. If not, it is recommended to call its customer prong phone consulting.

How to slow down the download speed of the computer

Several reasons for the slow speed of the network:

First, the network itself (server bandwidth is insufficient or too large a load)

Second, the problem of the network cable leads to slow down the network (twisted-pair cable is not in specification, the performance is: a situation is just beginning to use the network speed is very slow; the other situation is the beginning of the network speed is normal, but after a period of time, the network speed is very slow.

Third, there are loops in the network to slow down the network

Fourth, network equipment hardware failure caused by broadcast storms and lead to slowdown

Fifth, a port in the network to form a bottleneck leading to slowdown

Sixth, the impact of worms and viruses lead to slowdown

Seventh, the firewall's excessive use of

VIII, insufficient system resources

Slow Internet is mainly caused by the above reasons, I recommend that you, first clean up the computer's garbage process, optimize the system, and Trojan horse is also a pest!

Second, check whether the twisted-pair cable is qualified.

iii. Use the partitioned segmented step-by-step elimination method to eliminate loop failures.

Fourth, under DOS with the "Ping" command on the computer involved in the test one by one, the network card, hubs, and switches are the most likely to malfunction caused by the slowdown of the network equipment.

V. Replace the server NIC with 100M or 1000M, install multiple NICs, divide multiple VLANs, and change the router configuration to increase bandwidth.

Sixth, you must upgrade the antivirus software used in a timely manner; computers should also be upgraded in a timely manner, install system patches, while uninstalling unnecessary services, close unnecessary ports, in order to improve the security and reliability of the system.

Can solve these problems, your Internet speed is fast

The computer loading speed is slow to death, how to do?

Don't mind if your computer is slow, just that you can't tune it and clean it.

First, every day before the shutdown cleaning

Steps: dual-computer computer - right-click on the C disk - point "Properties" - point "Disk Cleanup" - point "OK! "- and then click" Yes "- and then click" OK "------- cleanup process, you can see without your permission (you can point to" View file "Look, you know) into the "temporary files" were removed, the disk space more, on the D, E, F disk also use this method to clean.

Second, clean up at any time

Steps: Open the Web - point in the top row of the "Tools" - point "Internet Options" - point in the middle of the "temporary Internet files". internet temporary files" in the "delete files" - and then in the "delete all offline content" before the box with a check mark - and then click "OK! "- After clearing and then click "OK" -------- so that can be said to open the page and space to speed up.

Generally these two steps to operate, more time-consuming, so be patient, and finally remember to restart the computer.

My computer to open the file is very slow, how?

Optimize your computer:

1, "Start" - Run in the input msconfig - OK - start - in addition to the input method ctfmon other than the hook all removed. Reboot.

2, right-click on my computer - Properties - point advanced - point startup and failover settings - remove all the hooks - write debugging information to select "none" - OK - point advanced under the error reporting - point disabled - 2 times OK.

3, "Start" - open the Control Panel in the folder options - point to view - point to remove the end of the automatic search for folders in front of the hook - OK.

4, right-click on my computer - Properties - Hardware - Device Manager - double-click on the IDE controller - secondary channel - Advanced Settings - transfer mode are selected DMA - device type selected None - OK - the same settings for the main channel - OK.

5, right-click the C disk for disk cleanup and other options in the system restore cleanup.

6, "C:\WINDOWS\Prefetch (pre-reading files) and C:\WINDOWS\Temp (temporary files) in the things all deleted.

7, right-click the browser e - Properties - point 2 delete 1 clear (all to determine one by one) - OK .

8, empty the recycle bin.

(5, 6, 7, 8 points per month to clean up once that is enough.)

9. Turn off the debugger Dr. Watson, run drwtsn32, remove all except "dump all thread context"

10. Turn off the "system XP comes with the restore", right click on "My computer" properties, system restore. (It is recommended not to close, close only to speed up the system, but the computer is not good)

11. Turn off the "hibernation support": because the hibernation function accounted for the space of the hard disk is quite large, so turn off the better, the control panel - > Power Options - > hibernation (do not check)

12.

12. Speed up Win XP's online neighborhood browsing!

Open the registry click to: Start - Run - Enter regedit - HKEY_LOCAL_MACHINE/Software/Microsoft/Windows

/CurrentVersion/Explorer/Remoteputer/NameSpace. Select the key: {D6277990-4C6A-11CF-87-00AA0060F5BF}, delete the following unnecessary key, after restarting, you will find the desktop with many fewer icons

13. Speed up the switching of XP:

1: shorten the waiting time:

Open Registry Editor (Start - Run - type regedit). -Run-type regedit-)Find HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control,

Set WaitToKillServiceTimeout to: 1000 or less. ( Original setting value: 20000) That is, wait only 1 second when closing the program. Change the HungAppTimeout value to: 200 ( original setting: 5000), which means wait 0.5 seconds when the program error.

2: Let the system automatically close the program that stops responding:

Open the registry HKEY_CURRENT_USER\Control Panel\Desktop key,

set AutoEndTasks value to 1. ( original setting value: 0 )

3: MsConfig Most of the Most of your friends should be familiar with MsConfig, which is a built-in Windows setup tool. Click on the Start menu, select "Run", and then type "msconfig" in the entry box. The tab we want to get our hands on is the (Startup) tab, click on it, this tab shows all the programs that run when Windows starts up. Except for ctfmon, none of these programs are critical to Windows, so feel free to remove the ones you don't want. By removing some of the checkmarks, Windows will start faster and have more free system resources.

14. Cancel the compressed folder tool that comes with XP:

Click Start->Run, and type: regsvr......

The computer is running slowly, the loading item has been circling what is going on

Enhance the computer system speed to become faster methods. (Adding a memory stick can also solve the problem of a slow computer and also make it faster.)

1. Computer boot startup items, optimization. Open 360 security guards - boot acceleration.

2. Usually, you have to use 360 Security Guard and other tools to clean up the system garbage and temporary files generated by the Internet (ie cache), check and kill malware.

3. Try to set your ip to a static ip to reduce boot time.

4. computer desktop do not put too many files and icons, will make the computer response slower, the software try not to install in the c disk. c disk is too much, you can also use the 360 software manager - toolbox - software moving, to solve the problem.

5. Close some startup programs. Start - Run - enter msconfig - OK - in the "System Configuration Utility" window, select "Startup" - startup, in addition to the input method (Ctfmon), antivirus software, general programs can be turned off. 360 Software Manager - Toolbox - Software Moving, solve the problem. 360 software manager - computer acceleration, intelligent optimization boot acceleration.

6. It is recommended to install only one main antivirus program, install more than one will take up computer resources, will make the computer slower.

7. Regularly organize the disk fragmentation to organize, open my computer to organize the disk fragmentation of the drive - Properties - Tools - select the disk to open the "Disk Defragmenter" window! -analysis-defragmentation-system that begins to organize.

8. Regularly, clean up the dust in your computer.

9. Regularly clean and optimize your computer.

10. Computer hard disk used for a long time, will also make the computer slower, repartitioning and installation can repair the logic of bad, the computer will also be faster, the hard disk physical read and write speed is slow, can only be replaced with a good point! Memory sticks can also be erased to prevent oxidation.

11. High temperatures will also affect the life of the computer, pay attention to cooling. Download a LU Master to keep track of the temperature.

The system with a long time, the computer will certainly run slow, not the computer configuration is not good, but the computer garbage and plug-ins are too much, too many boot projects, resulting in the computer card, as well as the slow situation,

At this time, the best choice is to re-install the system,

Reinstallation of the system, only to change the computer system in the C disk, such as computers, D and E and F disk inside the files and things will not be less. The best way to do this is to reinstall the system.

Depending on the configuration of your computer, you can install WIN7 64-bit operating system. With the computer hard disk installation system, you can install WIN7 system, the specific operation is as follows: 1. First to ghost system base to ghost008/win7/ylmf/4086 download the latest free activation of WIN7 operating system:

2. Will be downloaded WIN7 64-bit operating system, unzip to the D disk, do not unzip to the C disk. Do not unzip it to the C drive.

3. Open the unzipped folder, double-click the "GHO image installer", in the open window, click "Install".

4. In the window that appears, the path to the ghost image file will be automatically added, select the partition that needs to be restored, the default is C disk, click "OK" button to automatically install.

What is the reason for the slow reading of the computer

Is not your computer a mess of junk files ah or plug-ins, etc., these are the reasons for the impact of the computer reading speed fast and slow, download the 360, you can remove the junk files and plug-ins, etc., so that the computer runs a lot faster obviously.

Computer Internet speed is normal is to open the page slow what is the reason ah?

The first thing you need to do is to get your hands on a new computer that is not as easy to use as the one you are using. Maybe it's just that the site you visit is more congested, you visit 163, sina these portals, or local operators to provide you with Internet access to try the site, if they are slow, may be too many windows open too much memory, or virtual memory is not enough. If you're on a broadband connection with someone else, then see if someone is downloading something.

It would be hard to explain why this is happening if there are no more viruses!
