is the Samsung R25 books ~ when I bought the vista system (very unwilling to have this system) processor is Intel (R) Core (TM) DuoCPU T2450@ 2.00GHZ 2.00GHZ Memory is 1.0G I want to ask, why is the usage rate of my computer cpu not stable~~ Sometimes it can reach 100%, sometimes it is very low~ Right~ I want to ask if the machine is added A 1G memory can not be better ~ reduce the use of cpu
hope that the master can tell me what the reason. Often there are netizens encounter cpu occupancy rate is too high, for this small series for everyone to summarize the CUP display occupancy rate The following nine possibilities are high:
1. Anti-virus software causes failure
Because the new versions of KV, Jinshan and Rising have added random monitoring of web pages, plug-ins and emails, the system burden is undoubtedly increased. Processing: There is basically no reasonable way to deal with it. Try to use the least amount of monitoring services. Upgrade your hardware.
2, the driver is not certified, resulting in 100% CPU resources
A large number of beta drivers flooded the Internet, causing difficult to find the cause of the failure. Handling: Especially for the graphics card driver, it is recommended to use Microsoft-certified or officially released drivers, and strictly check the model and version.
3, viruses, Trojans caused
A large number of worms quickly replicated within the system, resulting in high CPU utilization rate. Solution: Use a reliable anti-virus software to completely clean the system memory and local hard disk, and open the system settings software to see if there is abnormal startup. Regularly update and upgrade anti-virus software and firewalls, strengthen anti-virus awareness, and master the correct anti-virus knowledge.
4, control panel & mdash; management tools & mdash; service & mdash; RISING REALTIME MONITOR SERVICE point the right mouse button, changed to manual.
5, start -> run->; msconfig->; start, close unnecessary startup items, restart.
6, view & ldquo; svchost & rdquo; process.
svchost.exe is a core process of the Windows XP system. Svchost.exe does not only appear in Windows XP, but svchost.exe exists in Windows systems that use the NT kernel. Generally, the number of svchost.exe processes in Windows 2000 is two, and the number of svchost.exe processes in Windows XP has risen to four and four.
7, view the network connection. Mainly the network card.
8. Viewing network connections
When a computer with Windows XP is installed as a server, when it receives a connection request on port 445, it allocates memory and allocates a small amount of CPU resources to service these connections. When the load is too heavy, the CPU usage may be too high because there is an inherent trade-off between the number of work items and the responsiveness. You need to determine the appropriate MaxWorkItems settings to improve system responsiveness. If the value set is incorrect, the server's responsiveness may be affected, or a user may have too much system resources.
To solve this problem, we can solve it by modifying the registry: expand the [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceslanmanserver] branch in the Registry Editor, 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 and exit:
9, see if Windows XP uses the right mouse button to cause the CPU to occupy 100%
in the resource manager, when you right click on a Directory or a file, you will likely have the following problems: Transfer of any file operation will be possible at that time will stop the corresponding
network connection speed will be significantly reduced
all stream input /output operations For example, listening to music using Windows Media Player may be the cause of music distortion:
When you right click on a file or directory in the Explorer, when the shortcut menu is displayed, the CPU usage will increase to 100%. It returns to normal when you close the shortcut menu.
With the above nine reasons, you can easily find out the cause and restore your computer to normal levels. In the process of using the computer, it is inevitable that there will be many problems, and the use of various types of diagnostic software can sometimes play the role of "and the village". Frequent maintenance of your computer not only enriches your experience, but it also protects your computer to a great extent.
