What if the cpu usage is too high?

Common symptoms and handling of high cpu usage
[Edit] virus and other malicious programs in the system
Computer viruses, trojan programs, and advertising software all occupy computer resources and may cause 100% CPU usage.

Processing: Use anti-virus software and update it to the latest virus database; scan the system using Trojan scan tools; use Super Rabbit and other tools to eradicate rogue software. See Computer Security Protection entries.

[Edit] Too many web pages are opened
Flash and script programs contained in the web page occupy a lot of cpu resources, and opening a lot of web pages will affect computer performance. Note: computers with a CPU clock speed lower than 2.0 have obvious performance in this regard because of their slow computing speed.

Processing: ① do not retain too many useless web page windows; ② download flash and AD blocking tools to block web page elements occupying resources; ② check whether the opened page contains illegal or special JAVASCRIPT code;

[Edit] Hard Disk DMA mode is automatically disabled due to standby mode
It is said that the driver may have bugs. You can view the current transmission mode of advanced settings in the main/secondary IDE channels of "ide ata/ATAPI controller" in the Device Manager for inspection.

Solution: uninstall the IDE channel driver and re-install it automatically. In addition, it is said that "do not use sleep and standby for large hard disks larger than GB ".... Remaining full text>
