CPU occupancy rate of 100% processing method

Treatment of Q:CPU resource occupancy 100%

A: When we use the Windows XP operating system, we are slow to use it, and see the task Manager to find that CPU occupancy is up to 100%. What's going on here? The virus, hardware problems, or system settings have problems, in this article I will be from the hardware, software and virus three aspects to explain the system resource occupancy rate of why it will reach 100%.

When CPU usage is frequent 100%, the main problem can occur in some of the following areas:

Nine possibilities for high CPU usage

1, anti-virus software caused the failure

Because of the new version of KV, Jinshan, rising are 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% CPU resource consumption

A large number of beta drivers are flooding the web, causing difficult to find fault causes. Processing methods: Especially the graphics driver should pay attention to, recommend the use of Microsoft Certified or officially issued by the driver, and strictly check the model, version.

3, virus, Trojan caused

A large number of worms are rapidly replicating within the system, resulting in high CPU utilization. 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, grasp the correct anti-virus knowledge.

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

5, start-〉; run-〉;msconfig-〉; start, turn off unnecessary startup items, reboot.

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 Connection

When a 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 the value is not set correctly, the responsiveness of the server may be affected, or a user will 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_machine\system\currentcontrolset\services\lanmanserver] 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 the computer has more than 512MB of RAM, type "1024", or "256" if the computer has less than MB of memory.

9. See if Windows XP uses the right mouse button to cause CPU occupancy 100%

Recently reported that the use of the right mouse button in the resource manager will lead to CPU resources 100% occupancy, let's see what's going on?

Sign:

In the resource manager, when you right-click a directory or a file, you will likely have the following problems listed:

The copy operation of any file at that time will likely stop the corresponding

The speed of network connection will decrease significantly

All stream input/output operations such as using Windows Media Player to listen to music may be the cause of music distortion:

When you right-click a file or directory in the resource Manager, when the shortcut menu is displayed, the CPU occupancy rate will increase to 100%, when you close the shortcut menu to 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.
