No matter how powerful your computer configuration is, even if you use the latest Windows 7 system that can best use CPU parallel computing, you will always find that your CPU usage is high. What's even more frustrating is that there aren't any big software and games running.
But how big is the software?
The little icon that flashes in the lower right corner of your computer desktop every day is the little penguin, is it big?
For ordinary computer users, as long as In the usual state, the CPU is high, except for the anti-virus software scanning, almost the other reason is caused by QQ.
Maybe, you don't have multiple QQs, maybe you don't have many friends, but the following two tricks can make you completely reduce the burden on the CPU, and decompress the hard drive by the way.
The first trick: Radical, delete useless QQ friends and QQ group chat records
QQ is too easy to analyze the reason for the CPU is too high, chat records should be cleaned up!
QQ chat record is a database file Tencent's own format, when you join some active QQ group, without completely blocking the message, you may increase the chat history in thousands of tens of thousands of items every day. Yes, you are not chatting, but other people in the QQ group have talked.
QQ then keep writing to the hard disk, read, read, ah, soon, if you carefully look at the QQ chat log file, day, 3 G is even bigger.
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.
Okay, let's clean up the chat history between you and your friends. You may need to save it for a long time. This can be targeted cleanup. The key point is the QQ group chat record!
Open QQ Message Manager if you To delete all group messages, click on the “group” on the left side, click the right mouse button, click “delete message history” 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 won't 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, lowering QQ process priority
If your computer configuration is not too high, QQ chat records are often cleaned up, but also QQ is high CPU, what should I do?
The current dual-core or multi-core CPU allows the CPU to handle different tasks at the same time. The old single-core CPU has no way to do this. Although it can work with multiple threads, it is incomparable with multi-core. The case of the CPU. So, at this time, we can use the Windows Task Manager built into Windows 7, Vista or XP system to set the priority of the QQ process to “ below standard or “low” It’s much faster when we hang QQ and run other software or games. Because the QQ process is distributed to the frontiers, we want to occupy the CPU and queue up first.
As shown below:
The above two tricks, whether it is used alone or together, will bring you an obvious effect beyond imagination, often confused for CPU problems friends , give it a try!
