CPU usage is high at 100, what to do non viral

Change the system version to try,Now many well-known forums on the Internet have their own optimized systems,You install it and try it,Maybe it's a problem with antivirus software.,This has to be tested slowly.。 If none of the above fails, you can open the Task Manager and see which process is using the highest CPU. And then come the questions.

Our phenomena are similar, and mine has not been resolved. Hey......

A few days ago, my computer from 10 o'clock to 12 o'clock in the morning, the CPU will be as high as 100%, too, the system is not toxic, the hardware configuration is no problem, and it has not been solved on the Internet. Even if it's useless, if you start some processes that take up a little bit, will you not be able to "stuck" into an army? You think we're all using 586 machines?

Dizzy, I veto this.

Now there is no situation you said, and I don't understand why there is no such high CPU situation, I used to use XP SP2, and now I use XP SP3, and it has not appeared again when I installed Vista, what I said above is on SP2. It's not that there is a problem with SP2, my CPU is high, that is, it appears for a few days in a row, and after a few days it is fine, and after a few days it is fine, and it is always repeated like that, and the CPU temperature is high? It was a situation in the summer, and I was afraid that the heat dissipation would not be good, so I simply removed all the case covers, haha, during that time, it really became a "bare metal", haha.

Open the task manager to see which process has a high CPU usage, if you don't know the system process, it may be caused by a virus, if a user process has a high CPU usage, you can close the process!

Funny. The process is 100% hard disk broken??? I really don't understand. What kind of technology are you guys there who fix computers? You tell him to open all your hard drives, and then install the system. It is recommended to use "Computer Company Special Edition Ghost is 100% good."

Reinstall the system and try a different anti-virus software. Encountered this kind of problem and solved it.

Open the task manager, close all the useless processes, you try.

100% look at what the process is! How do you know if there is no virus? Swept with Rising? Rising swept the virus or not.

For 100% CPU usage due to different reasons, the solutions are as follows:

1. Failure caused by anti-virus software.

Since the new version of KV, Kingsoft, and Rising have all added random monitoring of web pages, plug-ins, and emails, it undoubtedly increases the burden on the system. Solution: Basically, there is no reasonable way to deal with it, try to use the least monitoring service, or upgrade your hardware.

2. The driver is not authenticated, resulting in 100% CPU resource occupation.

A large number of beta drivers are flooding the web, creating a cause of failures that are difficult to find. Processing: Especially the graphics card driver, it is recommended to use the driver certified by Microsoft or officially released, and strictly check the model and version.

3. Caused by viruses and Trojan horses.

A large number of worms quickly replicate inside the system, resulting in a high CPU resource usage rate. Solution: Use a reliable antivirus software to thoroughly clean the system memory and local hard drive, and open the system settings software to check for abnormal startup programs.

Frequently update and upgrade anti-virus software and firewalls, strengthen anti-virus awareness, and master the correct anti-virus knowledge.
