Do you find your computer can not work efficiently as it is supposed to do? But all the running parts are still working very well and not attacked by any virus. In fact, it is a computer alarm that you should do something to maintain your computer.
No matter you are a computer novice or veteran, it is necessary for you to learn some methods to improve computer performance in order to guarantee computer to work well for you.

If you always visiting the websites or downloading files or videos from Internet, you should know that it is a good habit to clear away a bunch of temporary files which are left by browsing websites. Such files are inevitable but you can get rid of them manually. You can open IE browser and choose “Internet Options”. In the dialog box, click “General” tab and click “Delete Files” in the “Temporary Internet files” column. And in the “Delete Files” dialog box, tick “Delete all offline content” and click “OK”. By doing this, you can free up disk space a lot and optimize PC performance.

You can close down devices that you do not use any more.
In fact, Windows system can install drive programs for all the devices as many as possible. Such behavior is good will but it slows down computer startup speed and takes up a lot of system resource. In order to solve this problem, you can open “Device Manager” by right-clicking “My Computer”—“Properties”—“Hardware” and click “Device Manager” in the column. In the tab, you can double-click the device you want to turn off, such as the function of “Printer Port”. In the “General” tab, you choose “Do not use this device (disable)” and restart the computer. All of these new settings go into effect immediately. If you want to start them up, you can change in the same tab.

If your hard disk is using NTFS file system, you can consider starting up the compressing function of NTFS. Choose the drive you want to compress and in the “General” tab, you can choose to compress disk so as to save disk space. In this way, you can free up twenty percent of disk space more or less. You had better compress C system disk in the “Safe Mode” because it can be more efficient for disks.

And besides, you can clear up the pre-reading files functions. Although pre-reading function of Windows XP can speed up computer, it just can work well for a very short time. Since the files in the prefetch folder are becoming larger and larger, it will cost system a lot of time to search data or files. Therefore, you should delete them regularly.

Among all the methods, here I recommend you to defragment disks. Defragmentation is the easiest way to operate. You can use the defragmenting program of Windows with a few of clicks in more than an hour. Or you can turn to professional defrag named “Advanced Defrag”. By doing this new tool, you just need to wait for few minutes by few clicks.

Since there are many methods to optimize PC performance, you should be patient to try all of them if you really want to improve computer performance.
