What should I do if the computer starts slowly？
What should I do if the computer starts slowly? Without changing the computer hardware, the following methods can improve the performance of the computer very well:
Method 1: Antivirus. Unplug the network connection, turn off the system restore, and use the latest version of antivirus software to kill virus in safe mode.
Method 2: Clean the disk and defragment the disk.
1. In my computer window, right-click the drive letter to be cleared — "Attribute" — "Clean Disk"-Check the files to be deleted-OK-Yes.
2. Clear the temporary files and start — Run — Enter% temp%-OK.
3. Clean up the registry and junk files with an optimizer or a super rabbit.
4. Close some startup programs and start-run-msconfig-start. Except for antivirus software and input method, general programs can be turned off.
5. Delete the unused program software.
6. Defragment the disk.
Method 3: Optimize the computer.

12. Close Dr.Watson, click Start-Run-enter the command "drwtsn32" to open the window of Dr.Watson, leaving only the option of "Dump all thread contexts" and unchecking the box in front of it.
13. Set the virtual memory virtual memory minimum physical memory 1.5— 2 times, and the maximum value is 2-mdash of physical memory; Three times. The virtual memory setting method is: right-click my computer — Properties-Advanced-Performance Settings-Advanced-Virtual Memory Change-Select the system letter in the drive list-Customize the size-Set the values in Initial Size and Maximum Value, then click the "Set" button, and finally click the "OK" button to exit.
14, modify the registry
(1) speed up the startup and shutdown. in [start]-> [run]-> type [regedit]-> [HKEY _ current _ user]-> [control panel]-> [desktop], and change the numerical data (5000) of the string value [HungAppTimeout] to [ Change the numeric data (20000) of the string value [WaitToKillAppTimeout] to 1000. In addition, in [HKEY _ local _ machine]-> [system]-> [current control set]-> [control], Change the numerical data of the string value [HungAppTimeout] to [200], and change the numerical data of the string value [waittokilservicetimeout] (20000) to 1000.
(2) Speed up the pre-reading ability and improve the boot speed. Type [regedit]-> [HKEY _ local _ machine]-> [system]-> [current control set]-> [control]-> [session manager]-> In the window on the right of [PrefetchParameters], change the numerical data of [EnablePrefetcher] as follows, such as changing the numerical data to 4 or 5 as suggested by using PIII 800MHz CPU or above.
(3) home version of speeding up broadband access: open the registry editor, find HKEY _ local _ machinesoftwarepoliciesmicrosoftwindows, add an item named Psched, and add a Dword value NonBestEffortLimit in the right window of Psched, and the numerical data is 0.
(4) Speed up the broadband network speed, open the registry editor, find HKEY _ local _ Machinesystem CurrentControlSetServicesTCP IP parameters, right-click the parameters in the right margin, and select "New" on the left — > DWORD value edge, name it "DefaultTTL", right-click the mouse to select "Modify", and change the value (40) to 80 (hexadecimal) or 128 (decimal). Then click Tcpip in the left pane to change the value of GlobalMaxTcpWindowSize to 7FFF.
(5) Accelerate the online neighbors to open the registry editor and find HKEY _ local _ machine/Sofeware/Microsoft/Windows/CurrentVersion/Explore/Remote Computer/namespace. Delete {2227A280-3AEA-1069-A2DE08002B30309D} (printer) and {D6277990-4C6A-11CF8D87-00A0060F5BF} (planned task) under it.
Methods and steps:
Step 1. Clean the dust in the computer regularly.
The dust in the computer can easily lead to the accelerated aging of components, resulting in the slow operation of hardware, and even lead to some failure to boot normally due to poor contact. For example, if the fan is not cleaned in time, the temperature of the computer will be too high, and it will be easy for the computer to start slowly. Therefore, it is necessary to regularly check the dust in the computer, especially the desktop computer. You should turn off the computer regularly, open the chassis, and blow it with a hair dryer or a cold air blower, which can effectively clean up the dust. Laptop computers can be cleaned regularly in some professional cleaning shops.
Step 2. Turn off the startup item optimally.
Some unnecessary startup items are forbidden to start automatically, and the startup items are kept except the input method (Ctfmon) and antivirus software, and other programs can be disabled.
Check the steps of optimization: (Take win7 as an example)
1) Click the "Start" menu and enter msconfig, enter or click the program in the bottom program search.
2) Click the "Start" tab, you can see some currently started programs, and all other programs can be disabled except the input method (Ctfmon) and antivirus software.
If you encounter a startup project that you don’t understand, you can go to the internet to find out the specific use.
Step 3. Set the virtual memory to a relatively large space. (Xiaobian introduced the relevant content before, and if you are interested, you can read: How to set the virtual memory best)
Memory is used to run the program, so the memory space is relatively large, which can ensure that the program runs faster, so that when the computer is turned on, the program can be started quickly. Especially for computers with relatively low computer configuration, it is suggested to set the virtual memory larger, which is beneficial to the computer boot.
Setting method: (win7 system)
1) Find "Computer" and right-click "Properties"
2) On the left menu, find "Advanced System Settings".
3) In the "Advanced" tab of the pop-up window, find "Settings" of the performance list.
4) In the "Advanced" tab of the "Performance Options" window, there is a virtual memory, then click "Change", select custom, and then expand the virtual content as long as it meets the capacity requirements, but it should not be too large.
Step 4. Regularly defragment the disk.
This is a way to clean up the system. Some uninstalled or junk files will make the computer load when it is turned on, so the startup speed will slow down. Therefore, regular defragmentation of the disk is conducive to speeding up the startup speed. In particular, the arrangement of the C disk is still very necessary.
Specific methods:
1) Turn on the computer, then click the hard disk to be cleaned, right-click the menu bar, and click Properties.
2) Then click "Disk Cleanup" in the pop-up box.
3) Then the option box for disk cleaning will pop up, make an option selection, and then click OK to start disk cleaning.
Step 5. Don’t put too many files and icons on the computer desktop, and try not to install the software on drive C.
Computer startup is loaded from disk C. Too much content in disk C will easily lead to slow startup, especially many people’s desktops, which are icons or shortcuts, so the system will be loaded every time it is started, which takes a lot of time and space. Also try to install the software on a non-C drive, and the memory mainly runs on the C drive. If there is too much software, the memory space will become smaller, and the boot will of course be slow.
Step 6. Install only one anti-virus software, and choose anti-virus software that takes up less memory.
Some people install multiple anti-virus software for anti-virus effect, which will make the computer slower, so it is best to choose only one anti-virus software, and because anti-virus software needs to be booted, try to find anti-virus software that takes up less memory. Such as nod32, or just install an auxiliary antivirus software.
Step 7. Usually, cclean and temporary files (ie cache) generated by surfing the Internet should be commonly used to kill malware.
Step 8. Delete the startup item in the registry (not recommended for beginners).
The computer boot speed is slow, and most of the reasons are that the system is slow to boot into the system due to too many boot items, and all the boot items have to be started before it can enter the system normally. Therefore, in order to improve the boot speed, it is necessary to minimize the startup items and delete all unnecessary startup programs. If you delete the startup item, you have to delete it in the registry. There are two places in the registry that are startup items.
Specific steps:
1) Click Start menu first, and then click Run, and a dialog box will pop up. Enter regedit in it, click OK, and then a dialog box will pop up.
2) Then find the root key in this order, HKEY _ Current _ UserSoftwareMicrosoft Windows CurrentVersionPolicy Explorerrun, and the box on the right is the startup item. Just delete some useless startup programs directly, and it’s OK.
3) The second position is HKEY _ local _ MachinesoftwareChemicrofTwindows CurrentVersionPolicy sexplorerrun, and the same right side is also the startup item, which has deleted some useless items.
