What is the high CPU usage? Fix the problem of high CPU usage (1)

In general, if the CPU accounts for 100%, our computer will always slow down, and in many cases we can solve it by making a little change without having to ask the prawn.

First, the reason analysis

1. When the machine slows down, the first thing we think of is the task manager, to see which one is The program accounts for a high proportion. If it is a large program, it can be forgiven. If the CPU is normal after closing the program, then there is no problem; if not, then you have to look at what program, when you check If you don't know what the process is, go to google or baidu search. Sometimes it is useless to end only. Under xp, we can combine the startup items in msconfig and turn off some unused items. In 2000, you can go to the next winpatrol to use.

2. Some commonly used software, such as browsers occupy a very high CPU, then upgrade the software or simply replace it with other similar software, sometimes the software and system will be a bit incompatible, of course we can Try the compatibility item given to us under the xp system, right click on the .exe file to select compatibility.

3. svchost.exe is sometimes a headache, when you see that one of your svchost.exe takes up a lot of CPU, you can go to the next aports or fport to check the corresponding program path, also That is what is calling this svchost.exe, if it is not C: Windowssystem32 (xp) or C: winntsystem32 (2000), then it is suspicious. Upgrade anti-virus software to kill it.

4. Right-clicking on a file results in 100% CPU usage. We will also encounter it. Sometimes it may be a problem to right click. The official explanation: first click the left button to select, then right click (not very understand). Unofficial: By right clicking on the desktop - Properties - Appearance - Effects, cancel "Use the following overeffects (U) for menus and tooltips". There are also some anti-virus software that will also affect the monitoring of files, you can turn off the anti-virus software file monitoring; there is the same reason for the monitoring of web pages, plug-ins, and mail.

5. Some drivers may sometimes have such a phenomenon. It is best to choose Microsoft certified or officially released drivers. Sometimes you can upgrade the driver appropriately, but remember that the latest is not the best. .

6. CPU cooling software, because the software will use the CPU idle time to cool down during the running, but Windows can not distinguish the difference between the normal CPU usage and the cooling software cooling instructions, so the CPU always Show 100%, this does not have to worry, does not affect the normal system operation.

7. When dealing with large word files, the word spelling and grammar check will make the CPU tired. Just open the word tool-option-spelling and grammar to remove the check spelling and grammar.

8. The CPU usage is high after clicking the avi video file because the system scans the file first, and checks all parts of the file and indexes it. Solution: Right-click on the folder where you saved the video file - Properties - General - Advanced, remove the tick for indexing to allow the indexing service to index the folder for quick searches.

There is a lot of reasons for the slow response rate. It is not necessarily a virus. How long has it been used? Have you cleaned up the registry? Clean up redundant files? And optimizing the system? Don't prevent your virtual memory from being set a bit larger, empty the temporary folder, turn off the useless program loaded by the system, and check if there are too many self-starting items~ in the control panel-management-service Turn off, the option of the folder option has no practical meaning to remove, control panel - system - advanced - performance - visual effects, select custom. Or simply try to optimize the performance ~ ~ system folder (windows), there is a folder called temp inside the things cleared ~

(1) optimize with optimization master, super rabbit;

(2)Remove unnecessary processes:

In Windows2k/XP, the following processes must be loaded -

smss.exe, csrss.exe, winlogon.exe , services.exe, lsass.exe, svchost.exe (can exist at the same time), spoolsv.exe, explorer.exe, Syste

m Idle Process;

(3) with 360 Or Jinshan Guardian scan, look at the boot project and rogue software, if the boot program is disabled, it can be disabled, you can use the software to automatically optimize the function optimization system, optimize the system and restart the system to see if the usage rate is reduced. The final solution is to reinstall the system to solve the general problem! ~
