How to speed up the computer hard disk reading and writing

First, software chapter

1. Set Virtual memory

There is a very large data interchange file on the hard drive, it is reserved for the system of virtual memory as a place, many applications are often used, so the system needs the main memory for a large number of data access, so the speed of access to this file is a very important factor in the impact of computer speeds! General Windows default to the system to manage the virtual memory, it will be required by different programs to automatically adjust the size of the exchange file, but such a large scale will bring additional burden to the system, so that the system operation slowed! In view of this, the user is best to customize the minimum and maximum virtual memory, avoid the constant size of the transformation. To set virtual memory, right-click My Computer to select Properties, and in the advanced option, in the Performance dialog box, set the virtual memory.

2, check the application software or driver program

Some programs slow down the system when the computer system starts. If this is the cause, we can start in safe mode. Because this is the original boot, Safe mode runs slower than if it is running normally. However, if you start with Safe mode and find that your computer starts faster than it normally does, it is possible that a program is causing the system to start slowing down.

3, desktop icons too many will trouble

Too many icons on the desktop can also slow down the system's boot speed. Each time Windows starts and displays the desktop, it needs to look up the icons of the desktop shortcuts and load them individually, and the more icons, the more time it takes. At the same time some anti-virus software provides the system to start scanning function, which will cost a lot of time, in fact, if you have turned on the anti-virus software real-time monitoring function, then the start of the scanning system will appear a bit superfluous, or this feature is prohibited! We recommend that you put the desktop icons that are not commonly used in a special folder or simply delete them!

4, ADSL caused by the system start-up slowed

By default, when Windows XP starts, the network device such as the NIC will be self-test, and if the IP address of the NIC is found to be configured, it may be the real reason for the system to start slowing down. At this point we can open the Local Area Connection property menu and double-click Internet Protocol in the general item to open the TCP/IP Properties menu. Configure the IP address of the network adapter to a value that has not been used in the public network (the default gateway is 192.168.1.1), such as 192.168.1.x,x between 2~255, the subnet mask set to 255.255.255.0, and default gateway and DNS for default settings.

5, the effect of the font on the speed

While Microsoft claims that Windows operating systems can install 1000~1500 fonts, there are problems when you install more than 500 fonts, such as: Fonts disappear from the application's font list and Windows start to drop dramatically. It is advisable to remove any fonts that are not used or not used in this recommendation, so that you can make the necessary backups first to avoid accidental deletion.

6. Delete Random Start program

What is a random startup program? A random startup program is a program that is loaded at boot time. The random Start program not only slows down the boot speed, and faster consumption of computer resources and memory, in general, if you want to remove the random start program, you can go to the "Start" list to remove, but if you want to detail, such as QQ, Popkiller, such as software, is not in the "launch" list to delete, to go " Affiliate application, "and then go to System Tools," go to "system Information", go in, press the "tool" of the above tool column, press "System Configuration Edit Program", go in, in "Start" dialog box, will list the random start program that loads when starting a computer in detail! XP system you can also in the "run" is input msconfig call the System Configuration Utility to terminate the system random Boot program, 2000 system needs to copy the Msconfig program from XP.

7. Remove background and close Activedesktop

I do not know whether we have noticed that we always placed on the desktop on the beautiful background, in fact, is very wasteful of computer resources! Not only that, but also slow down the computer in the execution of the application speed! Want to beautify the desktop, but slow down the speed of the computer, so we need to not use the background, On the desktop, press the right mouse button, then the content, and then in the Background dialog box, select None, in the "Appearance" dialog box, in the desktop preset green, black ... As for closing activedesktop, that is to tell you to close the Web screen from the desktop, such as the right mouse button on the desktop, and then the content, and then in the "Background" dialog box, there is a background, called Windows XX, that is the Web screen! So how to configure the system does not open.

8. Make Windows Slimmer

Compared to the DOS system, Windows is too large, and as you do every day, installing new software, loading the runtime, adding new games, and so on makes it larger, and more importantly, not just its directory, but also its registry and runtime library. Because even if a program is deleted, the DLL file it uses will still exist, and as the days go on, Windows starts and exits with DLL dynamic-link libraries that need to be loaded, and the natural system is running slower and faster. Then we need to use some of the programs that completely remove the DLLs, which can restore windows to a slim figure. It is useful to recommend that the best players reinstall Windows every two months.

9. Change the system boot time

Although you already know how to add and remove some random launcher, do you know what the computer is doing during the boot up to the time you enter Windows? Or, what program is being executed? Do you ever think about the programs that have to be fully loaded before you start entering Windows? If you can remove some unnecessary boot on the program, the speed will be faster when the boot? The answer is YES! Want to modify, you can press "Start", select "Execute", and then type Win.ini, open, you can delete the contents of the following paragraphs, is deleted content, do not even delete the title! They include: [ Compatibility], [compatibility32], [imecompatibility], [compatibility95], [modulecompatibility], and [embedding].

Second, hardware chapter

1. Windows system shuts down hard disk DMA mode

DMA mode for hard drives everyone should know that the hard disk pata mode has DMA33, DMA66, DMA100 and DMA133, the latest SATA-150 are out! Generally speaking, most people now use the PATA mode hard drive, The hard drive uses DMA mode to transfer faster than the previous PIO mode 2~8 times. The function of DMA mode plays a substantial role in the performance of the system. But you know what? Windows 2000, XP, and 2003 systems sometimes turn off the DMA mode of the hard drive and automatically use PIO mode instead! This causes the hard drive performance in the above system to drop suddenly, the most obvious phenomenon is: the system start speed obviously slows down, generally speaking normal windows XP system startup, the left and right movement of the slider to go 2~4 the system can start, but this problem occurs when it may go 5~8 times or more! And when running the system when the hard disk operation obviously slowed down, in the running of some large software CPU occupancy rate is often up to 100% and a pause, Play some large 3D game when the screen has a clear pause, when the above problems, you should look at the DMA mode of your hard disk is not by the Windows system itself shut down. To see if your system turns on DMA mode:

A. Double-click Administrative Tools, and then double-click Computer Management;

B. Click System Tools, and then click Device Manager.

C. Expand the IDE ATA/ATAPI controller node;

D. Double click on your "Primary IDE controller";

2, the CPU and fan is normal operation and enough refrigeration

When the CPU fan speed slows, the CPU itself will increase the temperature, in order to protect the security of the CPU, the CPU will automatically reduce the operating frequency, which causes the computer to run slowly. There are two methods to detect the temperature of the CPU. You can use the finger method to try the processor temperature is hot, but note that this method must first unplug the power, and then a grounding wire to prevent the body with the electrostatic breakdown of the CPU and damage. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.

Due to the different types and models of the processor, the reasonable temperature varies. But overall, the temperature should be below 110 degrees. If you find that the processor's test is above this temperature, check to see if the fan in the chassis is working properly.

3, USB and scanner impact

When Windows starts, the individual drives, including the optical drive, are detected, so if the CD is placed on the CD drive, the computer's startup time is prolonged. So if the computer has installed scanners and other devices, or when the USB hard drive has been connected at startup, try disconnecting them first to see if the startup speed is changing. Generally speaking, because the USB interface speed is slow, so the corresponding device will have a more obvious impact on the computer startup speed, should try to connect the USB device after starting. If you do not have a USB device, it is recommended that the USB feature be turned off directly in the BIOS settings.

4, whether the use of disk compression

Because "disk compression" may cause computer performance to drop dramatically, resulting in slower system speed. So then you should check whether the use of "disk compression", the specific action is in the "My Computer" right click, from the pop-up menu select the "Properties" option to examine the drive properties.

5, the impact of the network card

As long as it is improperly set, network card will also significantly affect the speed of the system, your computer if connected to the LAN, install the NIC driver, the system will automatically obtain the IP address by default, but most of the company's LAN does not have a DHCP server, so if the user set to "Automatically obtain IP address , the system will continue to search the network on the DHCP server, until the IP address or timeout, natural impact on the start time, so the local area network users better for their own computer to specify a fixed IP address.

6. folder and Printer Sharing

Windows XP Professional version of the computer will also appear to start very slowly, sometimes the system seems to give people the feeling of panic, login system, the desktop does not appear, the computer is like stop reaction, 1 minutes before normal use. This is due to the use of the Bootvis.exe program, where the Mrxsmb.dll file for computer startup added 67 seconds!

To resolve this problem, simply stop sharing folders and printers: select start → settings → network and dial-up connections, right-click Local Area Connection, select Properties, and cancel the check box before "File and printer sharing on Microsoft network" under "This connection uses the following selected components" in an open window , restart the computer.

7. Improper configuration of system fittings

Some users often neglect some small things when assembling the machine, thus causing improper collocation of the whole computer accessories, and there is a bottleneck on the speed. For example, some friends choose the CPU grade is very high, but the sound card, etc. but bought a common bargain, in fact, this is often the loss of the candle. Because of this computer in the game, video playback because the sound card occupies a high CPU resources and its data transmission speed is slow, or it has no hardware decoding and need to use software decoding method, often cause sound pause, even cause the operation of the program intermittent. And as some of my friends ' machines were upgraded, in the past, some parts of the old machine such as memory will not be discarded, installed in the new machine, but due to the speed of the old memory limit, often make the new machine must reduce the speed to accommodate it, thereby reducing the performance of the whole machine, greatly affecting the overall speed of operation.

9. Disconnect unused network drives

To eliminate or reduce the number of network connections that Windows must re-establish, it is recommended that you disconnect some network drives that you do not need to use, that is, go to my Computer, right-click the network drive that you have mapped, and choose Disconnect.

10, lack of enough memory

One of the advantages of the Windows operating system is that it is more linear and multitasking, and the system can use the CPU for time-sharing, so that you do a lot of things at the same time. But things are good for nature, and multitasking can be a higher requirement for your machine. Friends know that even one of the most commonly used word software requires a good 16MB of memory, while running large software such as 3D Max, 64MB of memory is not enough. So at this time the system will automatically use hard disk space to virtual main memory, for running programs and storing Exchange files and various temporary files. Because the hard disk is a mechanical structure, and memory is an electronic structure, the speed between them varies by several orders of magnitude, so the use of hard disk to virtual main memory will cause the program to run a significant reduction in speed.
