What should I do if the CPU usage is high? CPU usage is too high Cause analysis (1)

What is the CPU usage high? CPU usage is high. Reasons for resolution
High CPU usage is high. The reason why Vagaa takes up too much system resources and causes system slowness and crashes has always been a hot topic for everyone. According to Vagaa's official explanation, Chinese online official software] caused by conflict, in fact, this is only one reason. I want to talk about my own opinions here, throwing a piece of bricks, hoping to attract everyone's jade and discuss together. Speaking of conflicts, in fact, Kad network and some IE plug-ins conflict, the first evil is [Chinese online official software], as long as the application of Kad network p2p software will happen, not only Vagaa. These are all well solved, as long as the useless IE plugin is uninstalled. According to my analysis, there are still several reasons for the CPU 100%. When there is a problem with a downloaded file, Vagaa may continue to try to repair it, causing a large amount of system resources. The solution is to delete the problematic file. 1. Anti-virus software causes failures Since the new versions of KV, Jinshan, and Rising have added random monitoring of web pages, plug-ins, and emails, the system burden has undoubtedly increased. 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 the graphics card driver. Pay special attention to the use of 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 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 - Administrative Tools - Services - RISING REALTIME MONITOR SERVICE Click the right mouse button and change to manual. 5. Start -> Run -> msconfig -> Start, close unnecessary startup items, and restart. 6. View the "svchost" process. Svchost.exe is a core process of Windows XP. 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 or more. (More computer and computer basics to get started, please go to http: //www.pc6c.com computer knowledge network). 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 many 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 value named "maxworkitems" in the right window. . Then double-click the value, type the following values ​​in the window that opens and save and exit: If the computer has more than 512MB of memory, type "1024"; if the computer's memory is less than 512 MB, type "256". 9, see if Windows XP uses the right mouse button

caused 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 how it is back. thing? 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. Double-click "Display" in the "Control Panel" 3. Click in the "Display" property. "Appearance" tab 4. Click "Effect" in the "Appearance" tab. 5. In the "Effects" dialog box, clear the check box in front of "Use transition effects for menus and tooltips" and click "OK" twice. " 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 bring up the shortcut menu. CPU occupies 100% solution In general, if the CPU accounts for 100%, our computer will always slow down, and in many cases we can solve it by making a little change without having to ask those prawn. When the machine slows down, the first thing we think of is the task manager. Let's see which program is the proportion of the program. If it is a big program, it can be forgiven. As long as the CPU is closed after the program is closed. Then there is no problem; if not, then you have to look at what is the program, when you can not find out what the process is, go to google or baidu search. Sometimes it is useless to end. Under xp, we can combine some startup items in msconfig to turn off some unused items. In 2000, you can go to the next winpatrol to use. Some commonly used software, such as browsers take up a lot of CPU, then you need to upgrade the software or simply replace it with other similar software, sometimes the software and system will be a bit incompatible, of course we can try to give us under xp system That compatibility item, right click on the .exe file to select compatibility. Svchost.exe is sometimes a headache. When you see that one of your svchost.exe takes up a lot of CPU, you can go to the next aports or fport to check the corresponding program path, which is what is used. Svchost.exe, if it is not c:\\Windows\\system32 (xp) or c:\\winnt\\system32 (2000), then it is suspicious. Upgrade anti-virus software to kill it. Right-clicking on the file results in 100% CPU usage. We will also encounter it. Sometimes it may be a problem to click the right button. The official explanation: first click the left button to select, then right click (not very understand). Unofficial: By right clicking on the desktop - Properties - Appearance - Effects, Cancel "Use the following overeffects (U)" for menus and tooltips to resolve. There are also some anti-virus software that can also affect the monitoring of files. You can turn off the file monitoring of anti-virus software; the same is true for monitoring web pages, plug-ins, and emails. Some drivers may sometimes have such a phenomenon. It is best to choose a Microsoft-certified or officially-released driver. Sometimes you can upgrade the driver appropriately, but remember that the latest is not the best. CPU cooling software, because the software will use the CPU idle time to cool down when running, but Windows can't distinguish the difference between the normal CPU usage and the cooling software cooling instructions, so the CPU always displays 100%, so don't worry. It does not affect the normal system operation. When dealing with large word files, the word spelling and grammar checking will make the CPU tired. Just open the word tool-options-spelling and grammar to check the "check spelling and check grammar".

After clicking the avi video file, the CPU usage is high because the system scans the file first, and checks all parts of the file and indexes it. Solution: Right-click the folder where the video file is saved - Properties - General - Advanced, remove the tick for indexing in order to quickly search and allow the indexing service to compile the folder.
