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, anti-virus software caused the fault. 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, viruses, Trojan cause. 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-> startup, shut down unnecessary startup items, restart.
5, see the "svchost" process.
Svchost.exe is a core process WindowsXP 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
distinguish what is normal Svchost.exe process, and what is a virus process?
Svchost.exe keys is "HKEY_LOCAL_MacHINESoftwareMicrosoftWindowsNTCurrentVersionSvchost", each key represents a separate Svchost.exe group.
Microsoft also provides a look at the service system is running in the Svchost.exe list of ways for us. Take Windows XP as an example: Enter "cmd" in "Run" and enter: tasklist/svc in command line mode. The system lists the services. If you are using a Windows 2000 system, replace the previous "tasklist/svc" command with: "tlist-s".
If you suspect that your computer may be infected with a virus, appear abnormal Svchost.exe service if Svchost.exe file by searching can find anomalies. Generally only one Svchost.exe program in the "C:WindowsSystem32" directory will be found. If you find the Svchost.exe program in another directory, it is likely to be poisoned.
there is a method to confirm whether the poisoning Svchost.exe is a look at the process in the Task Manager in the execution path. However, since the task manager that comes with the Windows system cannot view the process path, a third-party process viewing tool is used.
above brief introduction of the relevant circumstances 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 Network Connections. Mainly the network card.
7, the network cards, video cards, sound cards uninstall and then reinstall the drivers.
8, reinstall the system, commonly used software, of course, you have to install the driver, with 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.
