Nine Possibilities Of High Occupancy Rate Of CPU

1, anti-virus software failure

As the new version of KV, Jinshan and rising stars have joined the random monitoring of web pages, plug-ins and mail, it has undoubtedly increased the burden of the system.

Handling: basically, there is no reasonable way to handle, try to use the least monitoring services, or upgrade your hardware.

2, the driver has not been certified, resulting in CPU resources occupying 100%

A large number of beta drivers are flooding the Internet, resulting in trouble finding.

Handling mode: especially for graphics card drivers, it is recommended to use Microsoft certified or officially released drivers, and check models and versions strictly.

3, virus, Trojan horse cause

A large number of worm viruses quickly copy inside the system, resulting in CPU occupancy rate is high.

Solution: clean up the system memory and local hard disk with reliable anti-virus software, and turn on the system setup software to see if there is any abnormal startup program.

Constantly update and upgrade anti-virus software and firewalls, strengthen the awareness of anti-virus, and grasp the right knowledge of anti-virus.

4, control panel - management tool - Service - RISING REALTIME MONITOR SERVICE right click to manual.

5, start > > Run > > msconfig->; start, turn off unnecessary startup items and restart.

6, view the "svchost" process.

Svchost.exe is a core process of Windows XP system.

Svchost.exe is not only found in Windows XP, but also exists in Windows system using NT kernel.

In general, in Windows 2000, the number of svchost.exe processes is 2, while in Windows XP, the number of svchost.exe processes goes up to 4 and 4.

7, check the network connection.

This is mainly NIC.

8, check the network connection.

When a computer with Windows XP is installed as a server, it will allocate memory and allocate CPU resources to provide services for these connections when receiving connection requests on port 445.

When the load is too heavy, the CPU occupancy rate may be too high, because there is an inherent trade-off between the number of work items and the responsiveness.

You need to identify the appropriate MaxWorkItems settings to improve the responsiveness of the system.

If the set value is incorrect, the response capability of the server may be affected, or a user can monopolize too many system resources.

To solve this problem, we can solve it by modifying the registry: in the registry editor, expand the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver] branch in turn, and 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 memory, type "1024"; if the computer memory is less than 512 MB, type "256".

9, let's see if Windows XP uses the right mouse button to cause CPU to occupy 100%.

Not long ago, the report said that using the right mouse button in the resource manager will cause the CPU resource to occupy 100%. Let's see what's going on.

Sign:

In the explorer, when you right-click on a directory or a file, you may have the following problems:

Copy operation of any document will be stopped at that time.

The speed of network connection will be significantly reduced.

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 explorer, when the shortcut menu is displayed, the CPU occupancy rate will increase to 100%. When you close the shortcut menu, it will return to normal level.
