The reason why CPU resources occupy 100% under Win7 is

. 1. The driver is not authenticated, causing CPU resources to occupy 100%. A large number of beta drivers flooded the Internet, causing hard-to-find failures.
2, anti-virus, anti-virus software caused a malfunction. Because some anti-virus and anti-virus software have added random monitoring of web pages, plug-ins and emails, the system burden is undoubtedly increased, and services can be selectively opened according to the situation.
3, caused by viruses and Trojans. A large number of worms are rapidly replicated inside the system, resulting in a high CPU utilization rate. Solution: Use the latest anti-virus software to perform anti-virus in DOS mode. Regularly update and upgrade anti-virus software and firewalls, strengthen anti-virus awareness, and master the correct anti-virus knowledge.
4, Start -> Run -> msconfig-> Start, close unnecessary startup items, restart.
5, 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 or more.
How can I tell which is the normal Svchost.exe process and which are the virus processes?
The key value of Svchost.exe is in "HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionSvchost", each key value represents a separate Svchost.exe group.
Microsoft also provided us with a way to view the services that the system is running in the Svchost.exe list. Take Windows XP as an example: Enter: cmd in "Run", and then type: tasklist /svc in command line mode. The system lists the services. If you are using Windows 2000, replace the previous <;tasklist /svc” command with: <;tlist -s”
If you suspect that the computer may be infected by a virus and the Svchost.exe service is abnormal, you can find the abnormal situation by searching the Svchost.exe file. Generally only one Svchost.exe program in the directory: "C:WindowsSystem32” is found. If you find the Svchost.exe program in another directory, it is likely to be poisoned.
Another way to confirm that Svchost.exe is poisoned is to view the execution path of the process in the Task Manager. However, since the task manager that comes with the Windows system cannot view the process path, a third-party process viewing tool is used.
The above briefly introduces the Svchost.exe process. All in all, Svchost.exe is a core process of the system, not a virus process. However, due to the special nature of the Svchost.exe process, the virus will try to invade Svchost.exe. You can confirm whether it is poisoned by looking at the execution path of the Svchost.exe process.
6, view the network connection. Mainly the network card.
7, unload the network card, graphics card, sound card, and then re-install the driver.
8, reinstall the system, commonly used software, of course, also install the driver, take a few days to look at. If this problem does not occur, install other software, but it is best to use a software, first use a few days. If there is no problem, then install it.
