WinXP system has a CPU 100% problem solution

If the computer often appears 100% CPU usage, the main problem may occur in the following nine possible aspects of high CPU usage: 1, anti-virus software The failure caused the new version of KV, Jinshan, and Rising to join the random monitoring of web pages, plug-ins, and emails, which undoubtedly increased the system burden. Handling: There is basically no reasonable way to deal with it. Try to use the least amount of monitoring services, or upgrade your hardware. 2, the driver is not certified, resulting in 100% CPU resources. A large number of test version of the driver 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 to quickly replicate within the system, resulting in high CPU resource 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 the "svchost" 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 the network connection 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_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\lanmanserver] branch in the Registry Editor, and create a new DWORD named "maxworkitems" in the right window. value. Then double-click the value, type the following values ​​in the open window and save and exit: If the computer has more than 512MB of memory, type "1024"; if the computer memory is less than 512 MB, type "ldquo;256". 9, see if Windows XP uses the right mouse button to cause the CPU to occupy 100%. Not long ago, the report said that using the right mouse button in the resource manager will cause 100% CPU resources. Let's see what is going on? Symptom: In the Explorer, when you right click on 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 be significantly reduced all Streaming input/output operations such as 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%, return to normal level when you close the shortcut menu. Solution: Method 1: Turn off “Use transition effects for menus and tooltips> 1. Click “Start”--&"Control Panel" 2. In the "Control Panel" 3. Click on the "Appearance" tab in the "display" attribute; click on "Appearance" in the "Appearance" tab; <;> In the "Effects" dialog box, clear &ldquo ; use the transition effect for menus and tooltips> in front of the checkbox and then click twice to confirm the & rdquo; button. Method 2: Use the left mouse button to select your target file or directory when you right-click on a file or directory. Then use the right mouse button to pop up the shortcut menu
