What if the CPU usage reaches 100% after Windows 8 is installed?

Solution:

1. The driver has not been certified, resulting in 100% of CPU resources. A large number of beta drivers are flooding the Internet, leading to hard-to-find fault causes.

2. Faults caused by anti-DDoS and anti-virus software. Some anti-virus software has added random monitoring of web pages, plug-ins, and emails, which undoubtedly increases the burden on the system. You can choose to enable the service as needed.

3. Viruses and Trojans. A large number of worms rapidly replicate within the system, resulting in a high CPU usage rate. Solution: Use the latest anti-virus software to perform anti-virus in DOS mode. Update and upgrade anti-virus software and firewall regularly to enhance anti-virus awareness and master the correct anti-virus knowledge.

4. Start --- run --- msconfig --- start, close unnecessary startup items, and restart.

5. View the "svchost" process.

Svchost.exe is a core process of Windows XP. Svchost.exe not only appears in Windows XP, but also exists in the Windows system using ntinner. Generally, in Windows 2000, the number of svchost.exe processes is 2, while in Windows XP, the number of svchost.exe processes has increased to 4 and more.

For example, how can we identify normal svchost.exe processes and what are virus processes?

The key value of Svchost.exe is in the "HKEY_LOCAL_MACHINESoftwareMicrosoftWindows ntcurrentversionsvchost.exe. Each key value is assigned to an independent Svchost.exe group.

Microsoft also provided a method to check that the system is running in the svchost.exe list. Take Windows XP as an example: enter cmd in "run", and then enter tasklist/svc in command line mode. The system lists the services. If Windows 2000 is used, replace the previous "tasklist/svc" Command with "tlist-s.

If the computer is suspected to be infected by viruses, the svchost.exeservice can find exceptions by searching the svchost.exe file. Generally, only the svchost.exe program under the "C: windowssystem32”" directory is found. If you find the svchost.exe program in another directory, it is probably poisoned.

Another way to check whether Svchost.exe is poisoned is to view the process execution path in the task manager. However, because the job manager in Windows cannot view the process path, you must use a third-party process inspection tool.

Describes the process of svchost.exe. In summary, Svchost.exe is a core process of the system, not a virus process. However, because of the special nature of the svchost.exeprocess, the unique svchost.exe virus is also widely used. Check whether the execution path of the svchost.exe process is poisoned.

6. View network connections. This is mainly for NICs.

7. Uninstall the NIC, video card, and sound card, and then re-install it? Driver.

8. Reinstall the system, frequently used software, and of course install the driver. Take a look at it in a few days. If this problem does not occur, install other software, but it is best to finish the installation of one software, first use a few days. If no problem occurs, try again.
