There is too much rubbish on the computer. Clean it up . . Here are some practical skills that can greatly improve computer performance and make WinXP run faster and more reliable. I hope it will help you:
1) Installing Ultra- 133 hard disk acceleration expansion card or 8M cache ATA hard disk in the system can effectively reduce the startup time of the system.
2) Increase the memory to more than 5 12M.
3) Ensure that Windows XP uses NTFS file system. Check method: double-click "My Computer" and right-click drive C: select "Properties" to check the file system type. If it is FAT32, convert it to NTFS by backing up all important data, then select Run in the Start menu and enter CMD to confirm. At the prompt, enter CONVERT C: /FS :NTFS and enter. In this process, it is best not to interrupt abnormally in the middle and ensure that there is no virus in the system.
4) Turn off the file indexing function. Windows indexing service should extract information from a large number of files on the hard disk and create a "keyword index". If there are thousands of files on the hard disk, this function can speed up the search for information from these files. But it takes a lot of time for Windows to create this index, and most people never use this function. The closing method is: double-click "My Computer", right-click on the hard disk and the subfolder below, select "Properties", and cancel "Find files quickly by index". If a warning or error message (such as "Access Denied") appears, just click "Ignore".
5) Upgrade the drivers of the motherboard and graphics card, and upgrade the BIOS.
6) Empty the Windows read-ahead folder (Windows\Prefetch) every three months or so. Windows stores frequently used data in a pre-read folder, and when it needs to use these data again, it can greatly speed up the reading. But after a long time, there will be a lot of useless junk data in this folder, which will increase the reading time of Windows and affect the system performance.
7) Run the disk cleaner once a month to delete temporary and useless files. Methods: Double-click "My Computer", right-click the mouse on disk C, select "Properties" and click the "Disk Cleanup" button.
8) Double-click the IDE ATA/ATAPI controller in Device Manager and set the transfer mode of all connected devices to use DMA in the primary/secondary IDE channels (if available).
9) Update the wiring. After adopting a new hard disk, all IDE devices should be replaced with 80-wire Ultra- 133 cables at the same time. If only one hard disk is installed, the hard disk should be installed at the top of the cable, not at the interface in the middle of the cable, otherwise the signal may be abnormal. For Ultra DMA hard disk drives, these abnormal signals will affect the best performance of the drive.
10) Remove all spyware. There are many free softwares, such as AdAware, which can accomplish this task. After cleaning, all software containing spyware will not work properly. If you really need one of the softwares, please reinstall it.
1 1) Delete unnecessary programs in the startup group. Methods: Select Run from the Start menu, enter msconfig, enter the Start tab, and cancel the items that you don't want to load when the system starts. For uncertain projects, please check the WinTasks Process Library, which contains descriptions of known system processes, applications and spyware. It can also be found in online search engines such as Google.
12) Enter the "Add/Remove Programs" item in the control panel to delete unnecessary and unused programs.
13) Close all unnecessary animations and active desktops. Methods: Click the "System" icon in the control panel, enter the "Advanced" tab, and set the "Performance". On the Visual Effects tab, select the "Customize" radio box to set the related user interface functions to a disabled state.
14) Edit the system registry with Tweak-XP software to further improve the performance.
