This is due to a conflict between QQ and the system. It should be rarely encountered in XP. If it still doesn't work after re-downloading. Many people feel that when using QQ to surf the Internet, the computer becomes very slow after running the program for a period of time. Use the task manager to check the process and find that the CPU occupancy rate is very high. Is it not a problem of computer poisoning? In fact, it is caused by computer virus. This situation where QQ takes up too much CPU resources may be related to the settings of your QQ software. The problem can be solved by modifying the settings of QQ.

First: Reduce frequent pop-up messages in QQ groups, block the automatic pop-up chat messages of some QQ groups that are not frequently used, regularly clean up spam messages in QQ groups, and delete groups that are not used, otherwise As a result, too many residual chat records have accumulated.

Second: Turn off "Show custom avatars". Displaying your friends' various avatars may take up a lot of resources!

Third: Select "Recent Contacts" and click "Clear" "Recent Contact List" is also very critical; then select Interface Manager - Component Management - Folder Options - remove the check mark in front of Recent Contacts so that it does not display recent contacts. After many tests, recent contacts are displayed. People are the key factor causing the card, and this is also a very critical step in the solution in this article!

Fourth: Turn on "Only show online users", this is not necessary, because sometimes you need to find invisible users It is not convenient for friends

Fifth: Turn off "Show user prompts". If this function is not very important to you, you can cancel this function!

Sixth: Enter QQ system settings, turn off the settings in "Sound Settings" and block all friends' ringtones. Ringtone for all friends.

Seventh: QQ interface manager-panel settings are all cancelled, and the QQ search of component management is also cancelled.

Eighth: Go to the Program Files\Tencent\your qq number\ directory and check whether the chat database MsgEx.db or the chat emoticon folder is very large. I have reached 100M, what do you think? Is it possible to get rid of the lag? I can’t even check the historical chat records with my friends. Quickly consider making a backup of the chat records and then cleaning them up, or deleting the directory X drive\ProgramFiles\Tencent\your qq number\, and then Log in to QQ again and all records will start again, but remember to back up your chat history. It is best to make a backup copy of the entire QQ directory before deleting it.
