1. Clean and optimize registry
When Windows boot up, system needs to read data in the registry and put them in the ram temporarily. Windows spend most time in this regard. Therefore, it is necessary to clean and optimize registry. As for how to do that, you can turn to certain optimizer to help you.

2. Delete excessive dynamic library link files.
In the Windows-based operating systems, there are many dynamic library link files in the system subdirectory. Among them, some are shared by many files while some are quite useless. In order to free up disk space and improve computer speed, you can delete them on condition that you are skillful in computer technology.

3. Maintain system regularly.
If you have put too many games and applications with lot of old and useless data, it is no doubt computer is running slower and slower as well as booting computer.

Therefore, you should maintain computer completely at proper intervals. For example, to defragment disk is really a good way to improve computer performance. Besides, it is a must to defragment the disk where you put systematic programs. This is the right way to speed up starting up order of Windows correctly.

4. Expand virtual memory
If you have large disk, it is quite suitable for you to set virtual memory. You can point to a disk that is seldom used and then fix maximum and minimum values which is twice as that of physical memory. In this way, when virtual memory is applying hard disk, the value does not have to change unstably. Instead, system can apply fixed space as virtual memory so as to speed up read-write speed.

What is more, it is advisable for you to set the values after defragmentation because virtual memory should be put in a continuous space without any fragment. Only by doing this, it can play greater role in optimizing computer performance.

If you are eager to optimize computer performance, you should follow the steps one by one because I have introduced the main causes and solutions to improve computer performance in all-round way.

Many users are fans of using beautiful themes or wallpapers on the desktop. However, you have to pay for these beautiful things, that is, your computer must spend a large number of ram to support the extravagance in using resource. And excessive icons can slow down computer as well. Because system has to check whether it is needed to start up theme and then to load it, this is the way that so many themes take up a lot of memory.

At the same, system has to search and verify the validity of desktop shortcuts. That is to say, more shortcuts are there, more time the system has to expend. Therefore, it is advisable not to set themes. If you really want to do that, a piece of beautiful wallpaper is quite enough. And, you are able to classify these desktop shortcuts and put them into specific folder. By doing this, it is not only easy to administrate but can also speed up loading.

Then, since Anti-virus programs are hassles for computer as well, you can remove some of them if you have installed a lot of such programs. Some anti-virus software has provided to scan system when computer is booting. Well, the shortcomings of such function are overwhelming its advantages, because it may cost a lot of time without question.

As a matter of fact, if you have opened the real-time monitoring function and checked system regularly, it is unnecessary to scan the system when computer is starting up. You had better forbid such function so as to improve computer speed.

Besides, it is better not to set any memory optimizer software to work automatically when computer is booting. Even though computer administrates memory when starting up, it can do little help to computer but slow down starting up speed greatly. In fact, Windows has provided scientific and efficient administration to the memory and you do not need to do that by yourself.

Last but not least, do not forget to defragment disk regularly no matter using Windows programs or any other defragmenting programs. It can help you improve computer speed a lot.

In order to improve computer speed, you also need to clear registry and hard disk as well. Most importantly, it is to clear up computer regularly to keep computer in a good state with high speed.

In the very first place, it is the problem of network itself. The bandwidth of aim website server is not large or overloaded. This is the easiest problem and what you need to do is to change to other websites or change other to visit it.

Secondly, you may have used too many firewalls. If you use too many firewalls, it can slow down network for sure. The simplest way is to uninstall those unnecessary ones and just need to keep a powerful one, it is sufficient to serve very well for computer. You can remove such excessive firewall so as to improve net work speed.

And then, the system resource is too low. It is probably that there are excessive applications running in the background and computer is unable to spare enough resource for network. In order to solve this problem, you should load programs and delete useless applications and files properly so as to free up more space. By doing this, you can speed up network.

Next, computer worms may reduce network speed. Worm virus that is spread through E-mail has affected network more and more seriously. Such virus can force the affected users to send E-mails restlessly. Numerous junk E-mails are sent from your computer every second while millions of them are returned to your server in batches.

In this way, such rubbish is piling up in the server and slows down speed. As a result, you should upgrade anti-virus software and your computer and install patching program in time as well. And do not forget to uninstall those unnecessary services and to close down needless ports so as to improve safety and stability of system.

Besides, slow network problem may be caused by problems in internet cable, loops in the network, malfunction of network equipment and so forth. But they are quite professional for you. If you want to keep high network speedyou should form a good habit of using computer, such as clear up disk regularly.

1. Clear up disk space.
If you do not have high computer configuration and not clear up computer for a long time, it is likely that your computer is running slower and slower because the hard disk is crammed with too many junk files. If you computer is fast before but slows down recently, you need to clean up C disk as soon as possible. As for the junk files, you can the temporary and swap files, certain page files, history records files and so on. Most of them are hidden in the C drive.

2. By deleting the junk files in the C drive, your computer is able to run faster than before. Besides, you have to defrag C drive after wiping those junks. You can click “Start” > “All Programs” > “Accessories” > “System Tools”, you will see the defragmenting programs. And then it is necessary to clear up disk which is put in the same place as defragmenting one.

Next, set up a system restore point which is also in the “System Tools”. After doing that, you should close it down since restore point may consume a lot of C drive space. But it can help you restore the system to the normal state when you set up the point.

3. Uninstall some programs that you seldom use. It is undoubted that they take up too much space without doing any tangible things for computer. It is better to get rid of them, along with some useless functions such as “Error Reporting” and “Hibernation” which mean nothing for you but occupy the space.

4. Normally, when computer memory is too low, virtual memory will be created to solve such problem temporarily. You can set the value of virtual memory by hand. However too large or too small values can do harm to computer. You should set proper value for the maximum and minimum values respectively.

Slow computer is not so disturbing if you have grasped the correct methods to fix it. Besides, you can learn more about fixing slow computer problems by clicking the links.

1. You should back up importance registry files manually at proper intervals. In this way, computer will not be in a mess if system goes wrong but there are not alternative backup files at hand.

2. For common users, if computer is running normally, it is unnecessary to upgrade graphic card and BIOS and driver programs of main board. You may not know that too much upgrading can harm system performance as well.

3. You should avoid closing down computer abnormally in order to lessen the number of lost files, such as Dynamic Library Links files (DLL) which is quite important for smooth computer running. You should be patient enough to wait for the shutting down of your computer completely.

4. And you had better not install useless software as possible as you can. If you are not skillful enough, you should not uninstall or delete programs manually so as to reduce the number of illegal alternative files.

5. To be honestly, if you do not have large RAM and administrative programs, it is safe for you not to run large programs at the same time. What is more, if you find system is creaking when listening to MP3, the problems are caused likely by low memory.

6. You should check and optimize system files regularly. You can click “
Start”—“All Programs”—“Accessories”—“Command Prompt” and then type “sfc” so as to check lost files and proofread versions. Besides, you can clear up disk and defragment disk regularly as well. It is also a good method to prevent blue screen problems by freeing up more disk space.

Since blue screen is really a disaster for all the users, you should learn to prevent such accident in advance rather than to fix blue screen problem hastily.

First of all, you should check whether you have compressed disk or not. Since compressing disk can reduce computer performance seriously and slow down system speed for sure. Therefore, you should check whether you have used such function. Right-click the drive, click “General” to see if you have enabled to compress disk so as to free up disk space. It is better not to do that because it can decrease hard disk performance.

As a coin has two sides, though Windows-based systems are able to provide the service of running multiple tasks simultaneously, you have to tolerate the shortcoming of Windows operating system that is to manage files unclearly. Even sometimes you do not know whether this file is useful for computer or not. As time goes by, more and more files are increasing in the Windows directory, plus those swap and temporary files. They are consuming a lot of available disk space. When the available disk space is too little, there may be not enough space to support temporary and swap files which can slow down system running efficiency definitely.

More important, since you have restored and deleted much software frequently, it makes those available disk space fragmented. In this way, system has to spend more time in moving disk head when restoring and reading certain file. See, this is another cause of slow computer speed. In order to fix low disk space problem, you need to free up more space by deleting junks files such as temporary and swaps files in the C drive or on the Internet. And you can try to defragment disk by running defragmenting program of Windows or other third-party tools like “Advanced Defrag”.

And, if your computer is not updated enough for supporting SP3 or SP4 but definite too many partitions, it also drags the startup computer system. Therefore, it is advisable for you not to set too many partitions if your computer have not prepared very well for that. This is because Windows has to load every partition when starting up. As the partitions are becoming more and more, it also has to spend more and more time to operate them. So, you should not take the risk to set too many partitions which have little use but slow computer speed.

In order to increase Windows speed it is necessary for you to keep hard diskrunning normally. If not, it is vulnerable of slow speed. In this regard, you need to spare no effort to protect your hard disk.

In some cases, blue screen is caused by exhausted system resource. When computer is running a relatively large task or restoring or copying certain files, it is possible to lead to blue screen. Such accident is too abrupt for users to face it. This kind of blue screen is mainly due to insufficient resource of system, users and GDI.

In order to fix this problem, you need to open the “System Information” by clicking “Start” > “All Programs” > “Accessories” > “System Tools” > “System Information” to see how many system resources are left. If the rest resource mentioned above is below fifty percent or less, it is likely to appear the problems such as error operation, blue screen and computer freezing up.

Therefore, you should try every method to reduce the expense of computer resource. You can reduce the number of loading programs and avoid running large programs at the same time. The so-called large programs refer to graphic, vocal and video software. For example, it is unnecessary to load task program, voice indictor, DOS driver program of graphic card and so forth.

You can free up disk space as well as save it.
There are many ways to free up disk space. First of all, free up space by deleting some temporary and swap files and cookies in the hard disk and Internet Explorer. And then, defragment your hard disk. Since too many fragments cram into the hard disk, it can expense much disk space without question.

To be honestly, blue screen is caused by various problems from hardware and software mainly, you should be quite careful to use you computer and do daily maintenance regularly so as to prevent blue screen problems.

First is to restart system.
When the system appears blue alert windows, you need to start up system. Under most circumstance, computer can go back to normal track by restarting computer. Normally, you can not start it by press “Ctrl + Alt + Del” but just press reposition button or turn off electric power to start up computer again.

After entering into system, you can check the error as follows:
1. Click “Start” > “Administrative Tools” and double-click “Event Viewer”,
2. In the “Event Viewer”, you can check the “Error Records” in the “Application” and “System” respectively.
3. Click the item and then you can check the detail of the failed startup service.
Or, you can type “eventvwr.msc” in the dialog box by clicking “Start” > “Run” and then you can enter into “Event Viewer” as well.

Second is to restore the “Last Known Good Configuration (your most recent settings that worked)”.
In fact, the blue alter can not bother you without specific reasons. Normally, it is caused by updating driver programs or installing certain software. Sometimes users delete some very important system files that can lead to blue screen probably. At this moment, you can restart the system and press “F8” quickly to choose “Last Known Good Configuration”.

By doing this, system can restore efficient information in the registry in the item of “HKEY/LOCAL/MACHINE/System/Current Control Set”. However, it is unable to fix errors caused by broken files or driver program problems.
Or you can choose to press “F8” and choose “Safe Mode” to see whether system can enter into it normally. If so, you have to be aware that problems are likely caused by driver programs or system service errors.

Third step is to see about the wrong code.
If you want to know the specific information of wrong code, you can look them up in the Microsoft official website. Do remember the code, especially the one of “0x0000001E”. In the website, you can find the details of problems.

In conclusion, if you have encountered blue screen problem, you should fix them step by step by using the methods mentioned above. But if they can not work well, it is a must to check your hardware.

Since some of programs in the Windows are extremely significant for computer, they should take priority of others. That is to say, such core program performance plays important in computer stable running. Well, how to enhance the performance of core programs in the Windows?

When there are several programs running in the Windows, it is normal that Windows may replace the memory which may not be used currently to hard disk in order to perform several programs at the same time within relatively little memory. However, the frequent replacement between memory and hard disk in the way can slow down the speed of performing programs for sure because system has to run come-and-go.

As for the core programs in the Windows, they have to face such replacement as well. If memory is too low when system is running certain program, Windows may put some of the core programs to the hard disk which are not used currently. Although programs are running smoothly in this way, it has to take more and more time to use these replaced programs again when you need them because system has to move them from hard disk to memory. In this regard, it may reduce system running efficiency without question.

Therefore if the memory is not large enough, you can set not to replace kernel programs and just let them always resident in the memory so as to optimize computer performance.

In order to do that, you can modify the registry. Click “Start”—“Run” and type “REGEDIT”. Then, you can open “Registry Editor”, find out “HKEY/LOCAL_MACHINE/SYSTEM/CURRENTCONTROLSET/CONTROL/Session Manager/Memory/ Management” and set up or edit DWORD value named “Disable Paging Executive” in the right blanket and then change the key value as “1” which means you have forbidden replacing core programs while 0 means you can allow such operation. Do remember to clear up registry after doing changes in it.

If your computer memory is too low, you can set the value of virtual memory properly so as to maximize the space for running programs smoothly.

Program performance is very important for computer running. If you want to optimize computer performance, it is necessary for you to consider optimizing program at first.

First of all, you can delete the unnecessary loading orders in the “config.sys” and “autoexec.bat”. Normally, all the orders in these two folders can be removed for sure. You can click “Start” > “Run” and type “MSCONFIG”. In the popping up windows of “System Configuration Utility”, you feel free to cross out the ticks of “config.sys” and “autoexec.bat”. After doing that, you may find it is faster to start up computer without those useless files.

Second, delete the shortcuts in the starting up group. Some software can add starting programs to starting up group automatically. If such programs are piling up excessively in this group, it is no doubt that it can slow down system starting up speed. Therefore, you can get rid of certain programs so as to improve computer booting speed.
Right-click “Start” menu and choose “Open”—“Programs”—“Startup”. In this folder, you can delete all the shortcut icons because they are quite unnecessary for computer but just slow down starting up speed.

Third, uninstall resident programs in the system. Some programs can start up as system is booting, but their shortcuts do not display in the “Start”—“All Programs”—“Startup” menu. So, you can delete these programs. In the “System Configuration Utility”, you click “Startup” tab, you can choose the resident programs that you do not use frequently and delete them. By crossing out these programs, you can speed up computer obviously.

What is more, you can finish all of the operations mentioned above by using certain orders so as to optimize starting groups quickly. However, in the Windows 2000, there is no such function. If you want to do optimization, the only thing you can do is to alter registry. Is it disturbing? As a matter of fact, you can copy this program to system folder of Windows 2000. And you can just run it.

In conclusion, slow computer speed is really troublesome, you should try every method to speed up computer.
