How to solve the problem of excessive CPU usage in Windows 7 system?

Regardless of how powerful the computer configuration is, even with the latest Windows 7 system that can best use CPU parallel computing, you will always find that the CPU usage is high and there are no big software and games running. However, how big is the software? For ordinary computer users, as long as the CPU is still high in normal state, in addition to the anti-virus software scanning, almost other reasons are caused by QQ.

The first trick: radical, delete useless QQ friends and QQ group chat records

QQ is too easy to analyze the CPU usage, chat records should be cleaned up! QQ The chat record is a database file, Tencent's own format, when you join some active QQ group, when you don't completely block the message, you may add thousands of tens of thousands of chat records every day. There is no chat, but other people in the QQ group chat. In this way, it will put a greater burden on the usual QQ. The three G files are read and written back and forth, and the load on the CPU and hard disk is very large. After all, every time a message is received, QQ will open the large file, stuff it into it, and save it. Chat records with friends may need to be saved for a long time, can be targeted cleanup, the focus is QQ group chat record!

Open QQ message manager, if you want to delete all group messages, click on the left side ; group & rdquo;, click the right mouse button, click “ delete message records & rdquo; Or, clean up some of the specified groups separately and use the right mouse button to operate. Don't underestimate this seemingly simple technique, this will make your CPU take up a huge amount of reduction, you will not feel the card when you run the computer. At the same time, the life of the hard disk is also long.

Second trick: distribution of borders, lower priority of QQ process

If your computer configuration is not too high, QQ chat records are often cleaned up, but QQ still takes up CPU High, what should I do? Now the dual-core or multi-core CPU can let the CPU handle different tasks at the same time. The old single-core CPU has no way in this aspect. Although it can work with multiple threads, it can't be compared with multi-core. Many times, the program appears to grab the CPU. Therefore, at this time, you can use the "Windows Task Manager" built into Windows 7, Vista or XP system to set the priority of the QQ process to "below the standard" or "low", so that It’s much faster to run other software or games while hanging QQ. Because the QQ process is distributed to the frontier, want to occupy the CPU, queue first.
