Hello everyone, Lin Fei to answer the above questions, how to solve the problem of slow response of computer, many people do not know the solution of slow response of computer, now let's take a look at it!

Generally speaking, portable computers open much faster than desktop computers. Then the desktop computer runs slowly, it must be because there is something wrong with it. One is that there is a lot of dust in our computer, which is not cleaned up by us on time. There is also a biggest problem, that is, the computer has been infected with a virus and has not been killed! Of course, there is another problem that can not be ignored, that is, we often download files, in which the junk files have not been cleaned up, resulting in the slow running speed of the computer.

There are many reasons why computers are slow, the most important of which is the configuration of your own computer. Generally speaking, when the computer is configured, it must run fast. General computer configuration mainly refers to the computer's processor (cpu) memory directly affects the speed of the computer. Generally speaking, dual-core processors are better, but it does not mean that the higher the computer configuration, the faster the speed, because when the computer reaches a certain level, the simple programs we use do not reflect the speed changes of the computer. For example, with the same configuration of dual-core computers and quad-core computers, the speed of opening the same web page is basically the same, so there is no need to blindly follow suit when buying a computer. High-configuration computers are often expensive, but you only play simple games, and the general configuration can fully meet your requirements.

If you want to say that the computer users have the biggest headache, it is that the computer runs slowly. It takes a long time to open a program, but it takes a long time to close a program. If it hasn't been closed for a long time, even if you right-click "refresh", you will have to wait for a long time. So how to solve this problem? So let's take you to find a solution to the slow running speed of the Bianchao computer.

Methods / steps

Clean the dust on the chassis (if it is a laptop cleaning fan dust). In fact, many people's computer cards run slowly, which is actually caused by the poor heat dissipation of CPU and graphics cards. Due to the protection mechanism, they work less frequently, which leads to special computer cards. This mainly happens in computers that do not clean up their chassis (laptops) in the summer or during the year.

Kill computer viruses and Trojans. Recently, many computers have become very slow. You should pay attention to it at this time. Your computer may have a virus, causing your computer to be inefficient. Use antivirus software to kill virus thoroughly, and then use systems such as 360 first aid kit to repair the software repair system.

Clean up startup entries. Let the computer be light. Many computer families do not pay attention to installing software, resulting in too many startup items. They always carry these "baggage" when the computer is running normally, causing the computer to slow down (for example, QQ, Xunlei 7, Kuwo and many other software are turned on by default). Click start-run-enter MSCONFIG- to start closing all projects that do not need to be started (you can check all items and open them manually when you need some software)-OK-restart the computer.

Clean up the computer trash. Some people's computers have not been cleaned since they were bought. They only know how to install software into a computer, but they don't uninstall unnecessary software. Even if a lot of software is uninstalled, there will still be residual information in the computer. Click start-programs-Control Panel-add or remove programs, uninstall unused software, and then use Master Lu or 360 Security Guard to clean up computer junk files (cache, registry residue, etc.) .

Finally, defragment the disk, double-click to open "my computer", right-click on the top of the drive letter-Properties-tools-start defragmentation to complete.

Eliminate the bad path of hard drive. After long-term use of the computer, there will be a lot of wear and tear on the hard disk. Hard disk damage usually starts with a small number of bad channels, and then becomes more and more serious. Use the software (Baidu search hard disk bad road elimination tool) to find out the bad road, mark or hide, the next time you use the hard disk directly eliminate the bad road, speed up the hard disk running speed.

Set up virtual memory. All programs running in the computer need to be executed through memory. If the program you are executing takes up a lot of memory, the memory will be exhausted. In order to solve this problem, virtual memory technology is used in Windows, that is, some hard disk space is set aside for memory use. Right-click my computer-Properties-Advanced-performance Settings-Advanced-Virtual memory changes-Custom size (1.5-3 times the physical memory).

22 ways to improve computer speed:

1. System program optimization

1) disable the special effects in the system properties. Click start Control Panel system Advanced performance Settings in Visual effects, and adjust the settings to determine the best performance.

2) my computer-Properties-Advanced-error reporting-choose to disable error reporting.

3)

4) "my computer"-"Properties"-"Advanced"-"performance"-"Settings"-"Advanced", set the virtual memory value to 2.5 times the physical memory, set the initial size and the maximum value to the same (for example, your memory is 256m, you can set it to 640m), and set the virtual memory outside the system disk (note: delete the original file when moved).

5) transfer the temporary IE folder to another partition: open an IE browser, select "tools"-"internet options"-"General"-"Settings"-"move folder", and set it to a partition other than the system disk.

2. Accelerate the turn-on and shutdown

1) first of all, open the "system Properties" point "Advanced" tab, open "Settings" in the "Startup and failure recovery" area, remove the two √ in the "system Startup" area, and then click "Edit" to make sure that the additional property of the startup item is / fastdetect rather than / nodetect, do not add the / noguiboot attribute first, because guiboot will be used later.

2) the next step is critical: open the "hardware" tab in the "system Properties", open the "device Manager", expand "IDE ATA/ATAPI Controller", double-click to open the "secondary IDE channel" properties, click the "Advanced Settings" tab, change the transfer mode of devices 1 and 2 to "DMA (if available)", select "none" if the device type can be selected, and click to determine the completion of the settings. The same method sets the main IDE channel.

3) set pre-reading to improve boot speed, open the registry and find

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters, the window on the right changes the value of EnablePrefetcher to 1 (0-disable pre-read, 1-pre-read application, 2-system start pre-read, 3-pre-read both). Computers with PIII 800MHz or above can try to change the value to 4 or 5.

4) by the way, speed up the shutdown. Open the registry (start-run-regedit), click "my computer" to open the "Edit" menu "find", type AutoEndTasks, click "find next". Double-click to open the result and change the "numerical data" to 1 (this is the program that causes the system to automatically shut down and stop responding). Then find HungAppTimeout under AutoEndTasks (set its "numerical data" to 2000 or less, recommended), and then find WaitToKillAppTimeout (set its "numerical data" to 2000 or less, recommended to 1000). By the way, modify the menu delay time. Find MenuShowDelay under AutoEndTasks. The value is in milliseconds. If you want to remove the menu delay, set it to 0. After modification, click "Edit" menu, open "find next" (shortcut key F3), continue to search, and modify all the results found in the previous step (note: the values should be the same).

5) use the above method to find WaitToKillServiceTimeout and set the same value as WaitToKillAppTimeout.

6) after enjoying the fun of extreme restart, we further accelerate the startup speed, open the "system Properties"-"Advanced"-"Startup and recovery" settings, open the editor in the "system Startup" area, and add / noguiboot after the fastdetect, so that the scroll bar will not be displayed at startup. If you like the scroll bar display very much, you don't have to do this step.

7) MsConfig. Select run-msconfig. What we are going to tamper with is the Startup tab, which shows all the programs that Windows runs when it starts. No program here is a matter of life and death for Windows, so feel free to get rid of what you don't want.

3. Reduce the waiting time of boot disk scan

Select "start → run" and type "chkntfs / chkntfs 0" in the run dialog box to set the disk scan waiting time to 0. if you want to ignore scanning a partition, such as disk C, when the computer starts, you can enter the "chkntfs / x c:" command. If you want to restore the scan of disk C, you can use the "chkntfs / d c:" command to restore all chkntfs default settings, except for the countdown to automatic file checking.

4. Turn off the debugger Dr. Watson

Run drwtsn32 to remove everything except "dump all thread contexts". Otherwise, if there is a program error, the hard drive will ring for a long time and will take up a lot of space. If you have encountered this situation before, please look for the user.dmp file and delete it, which may save dozens of megabytes of space. This is the scene of the error program and is of no use to us. Then open the registry and find

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionAeDebug sub-key branch, double-click the name of the Auto key below it, change its "numerical data" to 0, and finally press F5 to refresh to make the setting take effect, which completely cancels its operation. In addition, the memory.dmp that appears when the blue screen appears can also be deleted. In "my computer → properties → advanced → settings → write debug information → choose none".

5. Turn off system restore

Right-click "my computer" on the desktop, select "Properties", find "system restore" to remove, which can save a lot of space.

6. Turn off hibernation support

The hibernation feature takes up a lot of hard disk space, so turn it off if you don't use it enough. Open the Control Panel-Power options-hibernation tab and cancel the enable hibernation check box.

7. Cancel the support for ZIP compressed files

Click to start the → run, type in the middle of the "regsvr32 / u zipfldr.dll" double quotes, and then enter to confirm it. The sign of success is a prompt window that roughly reads: Dll UnrgisterServer in zipfldr.dll is successful.

8. Do not load DLL files (unload useless dynamic links)

Locate the registry at the following location:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer, and then create a double-byte value called AlwaysUnloadDLL with a value of 1. If you want to remove this optimization, simply set the key value to 0 (or you can simply delete the key).

9. Turn off error reporting

In the "system Properties" dialog box, select the "Advanced" tab, click the "error reporting" button, in the pop-up "error reporting" dialog box, select "disable error reporting" option, and finally click "OK".

10. Speed up window display

Open the registry editor and find the

Go to HKEY_CURRENT_USERControl PanelDesktopWindowMetrics, find the MinAniMate key in the right window, and change it to 0.

Turn off automatic updates

Right-click my computer, select Properties-automatic updates-turn off automatic updates, I will update my computer manually, and click OK.

12. Accelerate the display of the start menu

Open the registry editor and find the

"HKEY_CURRENT_USERControl PanelDesktopMenuShowDelay" primary key, appropriately reduce the value of the key, the minimum can be set to "0". If this method is not valid, from "Control Panel"-"display Properties"-"display effects"-"Advanced", deselect the "show menu shadow" item to speed up the start menu display.

13. Close the disk index

Open my computer-right-click the drive-"Properties"-cancel "use index to quickly find files".

14. Accelerate the automatic refresh rate

Run Registry Editor, find

HKEY_LOCAL_MACHINEystemCurrentControlSetControlUpdate, change the numeric data of Dword [UpdateMode] to [0].

15. Turn off automatic restart function

WindowsXP suddenly reboots when it encounters a serious problem, which can be removed from the registry. Open the registry editor, find "HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCrashControl" and change the AutoReboot key's dword value to 0.

16. Delete imposed attachments

Modify winntinfsysoc.inf with notepad, use the find / replace function, enter ", hide" (an English comma followed by hide) in the search box, set the "replace with" box to empty, and replace all, so that all the hide are removed; save and exit; run "add-remove programs" and you will see several more options in "add / remove Windows components" so that you can delete some useless attachments.

17. Automatic call to "Windows Messenger" is prohibited at startup

Run Registry Editor to find and delete

"HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunMSMSGS" this key to achieve.

18. Keep the desktop settings unchanged each time you start

Open the registry editor and find the

HKEY_CURRENT_USERSSoftwareMicrosoftWindowsCurrentVersion PolicesExplorer subkey branch, find NoSaveSettings below it, change its key value to "0", or delete the key entry directly.

19. Run the Defrag (disk cleaning) program when you start the computer

Open the registry editor and find the

HKEY_LOCAL_ MACHINESOFTWARE MicrosoftDfrgBootOptimizeFunction key, setting the key value Enable to Y equals on and N equals off.

20. Clear pre-read files

Delete all files in this folder periodically, in the Windowsprefetch folder of the installation disk.

21. Cancel disk capacity warning

After opening the registry editor, find the

HKEY_CURRENT_ user Software Microsoft Windows CurrentVersionPoliciesExplorer key, double-click the NoLowDiskSpaceChecks key and change its value to 1 and then OK. If this key value does not exist, create a new DWORD value named NoLowDiskSpaceChecks, set its value to 1 and then "OK".

22. Clear the page file on shutdown (clear the virtual memory)

Open the "Control Panel", click "Administrative tools" → "Local Security Policy" → "Local Policy" → "Security options", double-click the item "shutdown: clean up the virtual memory page file", click the "enabled" option in the pop-up menu, and click "OK".

The slow speed of computers is a great waste of our time. Take office workers as an example. Many engineers and designers need to design one kind of picture after another through computers and drawing boards. However, every stroke shown on our computer desk is very slow, which increases the measurement of office workers' work. Even when watching a movie, it takes two hours to watch an one-hour movie because it is slow, but also because it runs slowly! Then, it is the absolute truth that this problem must be solved properly.

At the end of this article, I hope it will be helpful to you.
