Two solutions for optimizing and improving computer running speed

I. BIOS optimization settings
On the BIOS settings homepage, go to the "advanced BIOS features" option and move the cursor to the "frist boot device" option,
Select by "Pageup" and "Pagedown". The default value is "Floppy". This indicates that the system will first read the startup information from the soft drive.
Extend the start time of the machine and shorten the life of the soft drive. So we want to select "HDD-0" directly from the hard disk boot, so that the boot will be faster than several seconds. In addition,
We recommend that you select "disabled" for "above 1mbmemorytest" in BIOS settings, and enabled for "quickpoweronselftest.
The settings in the "advanced chipset features" item have a great impact on the acceleration of the host. Please pay attention to them.
Change "Bank 0/1 DRAM timing" from "8ns/10ns" to "fast" or "Turbo ". "Turbo" is faster than "fast", but not stable,
We recommend that you select "fast ". If the memory quality is good, select "Turbo". If the memory quality is unstable, you can change it back to "fast ".
For memory-quality memory, we recommend that you set it to "2" in the "sdram cas latency" option to speed up.
Newer boards support agp4x, and if your graphics card also supports agp4x, activate it at the AGP-4XMode, that is, select Enabled ", this will give full play to the video card capabilities and speed up system startup.
Ii. Enable the DMA mode to increase the hard disk speed
The highest transmission rates of hard disks using udma/33, 66, and 100 are 33 Mb/s, 66 Mb/s, and 100 Mb/s. In theory, it is an IDE hard disk.
(Here it refers to the PIO mode4 mode, and its transmission rate is 16.6 Mb/s) 3 ~ of the transmission rate ~ 6 times, but in the default settings in windows, DMA is disabled.
So we must open it.
The specific method is to open the "Control Panel> system> Device Manager" window, expand the "disk drive" branch, and double-click the udma hard disk icon,
Go to "properties → settings → options", and "√" before "DMA". Then, press OK to close all the dialog boxes and restart the computer.
3. Remove the Windows boot mark.
First, open "start"> "Settings"> "Folder Options", and select "show all" from the "Advanced Settings" list box in the "View" tab.
File ". Open drive C, find the msdos. SYS file, cancel its "read-only" attribute, open it, and add a line under the "option" section.
Statement: logo = 0, so that the boot pattern of Windows will not be loaded and run, and the boot time can be shortened by 3 seconds.
4. Optimize the "Start" group.
Computer beginners love to use various software and delete it in a short time. However, for some inexplicable reason, these software will also reside in
In the "Start" project (especially when using some D version software), Windows will waste a lot of time to start it. To solve this problem
You can open "start"> "run", select "msconfig" in the "open" column of the displayed dialog box, and click "OK ",
The "System Configuration Utility" will be called up, and click the "Start" tab to remove the "√" before the program that does not need to be loaded into the Startup Group.
In this way, the startup time can be reduced by at least 10 seconds.
5. Organize and optimize the registry.
After windows is started, the system reads the relevant information in the Registry and stores it in RAM (memory). Most of the time windows is started,
All of them are spent on this. Therefore, it is necessary to organize and optimize the registry. For registry optimization, you can use software such as Windows optimization master.
Click "register information cleanup"> "scan" as a Windows optimization master, and the software will automatically clean up the garbage in the Registry for you. After the scan,
A menu will pop up asking you to select whether to back up the Registry. We recommend that you select backup, and then click "clear" after backup.

6. Always maintain the system.
If too many games, too many applications, and too many old materials are installed in the system, your computer will be slower and slower, and the boot time will
Is growing. Therefore, it is best to perform comprehensive maintenance on the computer at intervals. Click Start> program> attachment> System Tool"
→ "Maintenance wizard", and then click the "OK" button to perform a full maintenance on the computer, which will keep your computer in the best state. For hard
It is best to perform "disk fragmentation" every two weeks, which will significantly speed up program startup. Click "System Tools"> "disk fragmentation"
Program. Note that the system disk must be organized when disk fragments are sorted, so as to speed up the startup sequence of windows.
7. Expand the virtual memory capacity.
If your hard disk is large enough, open "system" in "Control Panel", enable "Virtual Memory" in "performance" option, and select "second ".
Item: you can set your own virtual memory settings to point to a hard disk that is rarely used, and set the maximum and minimum values to a fixed value. The size is physical memory.
About 2 times. In this way, when using a hard disk, virtual memory does not have to accommodate its sudden big and small differences. Instead, it uses a fixed space as the virtual memory to accelerate access.
Speed. It is best to set the virtual memory after "disk fragment", so that the virtual memory is not in a continuous, non-fragment file space,
Can play a better role.
8. Remove fancy settings such as wallpaper and screen protection.
These settings occupy system resources and seriously affect the startup sequence of windows. To remove them, right-click the blank area on the desktop,
In the pop-up menu, select "properties". In the pop-up dialog box, select the "background" and "Screen Saver" tabs, and set "Wallpaper" and "Screen
Set "Protection Program" to "NONE.
9. Delete autoexec. BAT and config. sys.
The system installs the autoexec. BAT and config. sys files under the root directory of the disk. Windows does not need them anymore. You can safely delete them.
To speed up windows startup.
10. Streamline the *. ini file, especially the content of system. ini and win. ini.
Many drivers and font files are loaded in the [boot] and [ENH] sections of system. ini, which is the focus of clearing. In particular, the [boot] Character
The shelljavaser.exe field is a hidden loading place that Trojans like. Generally, Trojans change this sentence to the following: shelljavaser.exe file.exe,
In this example, file.exe is a Trojan server program! The subsequent loading and running of Trojans not only threatens system security, but also slows down the startup of the computer;
For programs loaded after "run" and "LOAD" in win. ini that are not required to run at each startup, You can temporarily clear them and click "run" when necessary.
In this way, the files related to Windows calling will be much reduced during boot, and the startup speed will naturally be much faster.
11. Disable disk scanning.
Open msdos. sys in a text editor and you will see the following:
[Options]
Bootmulti = 1
Bootgui = 1
Autoscan = 1
If you do not want to run the disk scan program after an abnormal shutdown, you can change atuoscan = 1 to autoscan = 0, so that the computer starts after an abnormal shutdown.
The speed will also be faster (because Scandisk is not running ).
12. Minimize the duration of the Guidance information.
Open msdos. sys in a text editor and set bootdelay in [Options] to 0.
13. Reduce Unnecessary font files.
Font files occupy a large amount of system resources, boot is slow, and occupy a lot of hard disk space. Therefore, reduce unnecessary font files as much as possible. However, if the deletion is incorrect
Font files may make windows abnormal. Therefore, you can use the following method to "steal a column" (you can install a font file without occupying
Use a large amount of disk space): First open the font folder (such as F:/ZK), select all TrueType font files, right-click them, and drag them
C:/Windows/fonts folder. In the pop-up menu, select "Create a shortcut at the current location" to create a shortcut under the system font folder.
The shortcut of the font file. When you need to use these font files, you only need to insert the font disc and retrieve it if you do not need it.
14. Delete unnecessary DLL files. There are many DLL files in the system subdirectory of the window operating system, which may be shared by many files,
But some do not have a file to use, that is to say, these files are useless, in order not to occupy the hard disk space and improve the startup speed, it is completely OK
Delete it.
15th, the "left by the door" approach. If the system is suspended, the current system status will be saved after shutdown. After the next boot, the system will directly go to the previous
In this way, the boot time can be up to 4-5 seconds before the desktop is shut down, but not all motherboard BIOS support, it is also a little troublesome to set up.
Open the registry and expand to the HKEY_LOCAL_MACHINE/software/Microsoft/Windows/CurrentVersion/shareddlls subkey.
There are many DLL files, if the data is 0, you can determine that the DLL file is not shared by the program, you can delete it.
If the boot speed of the computer is not fast enough, in addition to upgrading the hardware (CPU, memory, hard disk, etc.), another good way is to reinstall the system,
In this way, the computer startup speed can be significantly accelerated. If you don't believe it, try it!

16. disable unnecessary services

Solution 2

The start time is the time required to boot from the boot or hot boot to boot the operating system. The process mainly includes checking the hardware
So the CPU speed is the decision that affects the system startup speed.
Factors. However, reasonable configuration through software can also increase the startup speed of the machine to a certain extent.
Take the following measures:
Set the following items in CMOS:
1. system boot sequence = C: A: set to start from drive C first, eliminating the need to check whether drive A has a boot disk.
(If you do not often use a soft drive to start)
2. Floopy drive seek at boot = disabled do not search test floppy disk drive
3. The above 1 MB memory test = disabled does not detect memory of 1 MB or more
4. Quick power on selftest = Enable for fast self-check
5. Check config. sys and autoexec. BAT to Remove useless device drivers and memory resident programs.
6. If necessary, add switches =/f at the beginning of config. sys, which saves two seconds to wait for F2 and F8 to start dos.
7. when configuring the XMS memory driver, add the parameter device = C:/DOS/himem. sys/testmem: off, or device = C:/Windows/himem. sys/testmem: off to prevent Detecting extended memory
8. Add the drive letter and directory name to each command of the batch file to avoid searching one by path.
Response Speed
9. Do not add a CD to the optical drive during startup, eliminating the need for the optical drive to recognize the disk.
Windows users can also take the following measures to increase the startup speed of Windows:
1. Remove wallpaper and screen saver;
2. Reduce the number of programs on the desktop;
3. Reduce the window size of all program groups or applications;
4. Automatically scale down the non-current window;
5. Use the disk cache program.
　

Ii. Improve Running Speed: Top

The speed of the computer is directly dependent on the CPU performance, but it is highly related to the settings of other components and the software used.
System, pay attention to the following aspects:
1. in CMOS, system boot up CPU speed = high enables the machine to run at high speed
2. external cache = enabled in CMOS uses internal and external high-speed cache
3. In CMOS, system BIOS shadow = enabled uses the motherboard BIOS memory ing
4. Set the patch cord of the motherboard correctly. For example, if the CPU with a working clock of Hz is set to 66Hz on the motherboard, it can only run at a speed of Hz.
5. Reduce the TSR program in the memory. If the execution of a certain interrupted service program is modified or interrupted for too long
When this interruption occurs, the computer runs slowly.
　

Iii. Improve disk and file read/write speeds

The access speed of the disk depends on the type and performance of the disk drive used, and the file read/write speed.
The speed is determined by the combination of CPU and disk read/write speeds. The methods to increase the speed include:
1. flexible use of disk high-speed cache programs: for example, smartdrv in DOS is an excellent disk cache program. In addition, you can increase the speed of buffers in config. sys.
2. Perform disk fragmentation in a timely manner to clear disk space
3. Use appropriate commands in the operation. For example, the xcopy command is faster than the Copy command to copy a folder and its sub-files.
　

4. Increase the display speed
The display speed depends on the performance of the graphics card and the size of the display cache. The methods to increase the speed are as follows:
1. Modify video BIOS shadow = enabled in CMOS to make the display card memory ing valid.
2. Use a display card with the graphic acceleration function
3. Configure as many caches as possible
4. In Windows, do not pursue too high resolution and colors. The minimum requirements shall prevail.
5. Use random or common display driver resident programs in DOS
　

5. Increase the printing speed

The printing speed is limited by the printing type, printing method, computer speed, and the performance of the printed program.

1. Try to print with a printer hard font
2. Improve the printing speed by reducing the quality. Most dot-matrix printers provide high-speed printing and inkjet printers provide
Ink-saving status. The laser printer can adjust the scanning line density of the output, which can be used to increase the printing speed.
3. Select an excellent print driver. Pay attention to the driver updated by the manufacturer
4. Make full use of the Background printing function in Windows
　

6. Improve the Internet access speed
1. Select a modem with high speed and strong anti-interference ability to increase data transmission speed and security
2. If possible, try to use the text format work interface, because the image format will occupy a lot of communication time.
3. BBS users should use dos communication software as much as possible, because most of them are graphic in windows.
4. Turn off the sound and animation in the browser.
5. If your modem is connected to COM1 or com2, go to control panel and select system and device management. Find
To port COM1 or com2, set the baud rate to the maximum value.
