A summary and solution to the high CPU occupancy rate

In general, the CPU utilization rate is high our computer will slow down, and many times we always wonder why, this article briefly summed up its suspect and solution, and then encountered this situation when we can make a little change can be solved.

First, consider the virus!

Second: 1, anti-virus software cause failure due to the new version of KV, rising and other anti-virus software added to the Web page, plug-ins, mail random monitoring, undoubtedly increased the system burden. Treatment: Basically there is no reasonable treatment, try to use the least monitoring services, or, upgrade your hardware equipment.

2, the driver has not been certified, resulting in 100% large number of CPU resource consumption of the test version of the network flooding, resulting in difficult to find the cause of the failure. Processing methods: Especially the graphics driver should pay special attention to, recommend the use of Microsoft Certified or officially issued by the driver, and strictly check the model, version.

3, viruses, Trojans caused a large number of worms in the system of rapid replication, resulting in CPU utilization rate of resources is high. Solution: Clean the system memory and local hard drive with reliable anti-virus software, and turn on the system setup software to see if there are any abnormal startup procedures. Update anti-virus software and firewalls regularly, strengthen anti-virus awareness, master the correct anti-virus knowledge.

4, Control Panel-management tools-Service-rising Realtime MONITOR Service point the right mouse button, instead of manual.

5, Start---Run: msconfig---start, close unnecessary startup items, restart.

6, view the "Svchost" process. Svchost.exe is a core process of Windows XP systems. Svchost.exe not only appears in Windows XP, but there are svchost.exe in Windows systems that use the NT kernel. Typically, the number of svchost.exe processes in Windows 2000 is 2, and the number of svchost.exe processes in Windows XP rises to 4 and more than 4.

7, view the network connection. Mainly is the network card.

8. View network Connections when Windows XP computer is installed as a server, when you receive a connection request on port 445, it allocates memory and provides a small amount of CPU resources to service these connections. When overloaded, the CPU occupancy rate may be too high, because there is an inherent trade-off between the number of work items and the ability to respond. You need to determine the appropriate MaxWorkItems settings to improve system responsiveness. If you set an incorrect value, the server's responsiveness may be affected, or a user can monopolize too many system resources. To resolve this issue, we can resolve this by modifying the registry: In the Registry Editor, expand the [Hkey_local_machinesystemcurrentcontrolsetserviceslanmanserver] branch in turn, Create a new DWORD value named "MaxWorkItems" in the right window. Then double-click the value, type the following values in the open window and save the exit: If your computer has more than 512MB of RAM, type "1024", or "256" If your computer has less than the memory of MB.

9, to see if Windows XP use the right mouse button to cause the CPU occupied 100% before the report said the use of the right mouse button in the resource manager will lead to CPU resources 100% occupy, let's see what is going on? Indications: In the Explorer, when you right-click a directory or a file, you will likely have the following problems: Any file copy operation at that time will likely stop the corresponding network connection speed will significantly reduce all flow input/output operations such as using Windows Media Player listening to music will probably be the cause of music distortion: When you right-click a file or directory in the Explorer, when the shortcut menu is displayed, the CPU occupancy rate will increase to 100%, and when you close the shortcut menu, return to normal level.

Workaround:

Method One: Turn off "use transition effects for menus and tooltips"

1, click "Start"--"control Panel"

2, in the "Control Panel" inside double-click "Display"

3, in the "display" attribute inside click "Appearance" tab page

4, in the "Appearance" tab inside click "Effect"

5. In the "Effect" dialog box, clear the check box in front of the "Use transition effect for menus and tooltips" and then click the "OK" button two times.

Method Two: When using the right mouse click File or directory, first use the left mouse button to select your target file or directory. Then use the right mouse button to eject the shortcut menu.

Under normal circumstances, the CPU utilization rate is high our computer will slow down, through the understanding above, we can also solve the problem by ourselves.

When the computer slows down, the first thing to check the task manager, to see exactly which program accounted for a higher proportion, if it is a large program, in the shutdown of the program as long as the CPU is normal, then there is no problem, if not, you have to see what is occupied.
