WinXP System CPU Usage High detailed resolution method

Several possibilities for high CPU usage:

1, anti-virus software caused the failure

Some anti-virus software for Web pages, plug-ins, mail random monitoring, undoubtedly increased the system burden, such as Kaspersky Anti-Virus software, such as the performance of more prominent, to the user brought intangible trouble.

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 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.

Treatment method: Clean the system memory and the local hard disk with the 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 firewall regularly, strengthen anti-virus awareness, master the correct anti-virus knowledge, avoid the interference of Trojan horse. 4, Control Panel-management tools-Service-rising Realtime MONITOR Service point the right mouse button, instead of manual.

5, start-> run->msconfig-> start, turn off 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 window S 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 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 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 MB of memory.
