View the Windows hidden process, and use Microsoft processexplorer to check that there is a "Hardware interruption" on the computer that occupies a large amount of CPU. Solution

View the hidden process in the window. There is often a hidden process that occupies about 20% of the CPU. I don't know what the program is causing. It's very depressing.
I don't know how to find out the process that is not seen in the process that occupies a large amount of CPU?
Windows XP notebook. You can see it on the Internet by checking the ice blade or Microsoft processexplorer.
But the ice blade does not see the CPU usage of processes
The Window Process Manager can see the CPU usage, but cannot see the hidden process
Microsoft processexplorer can be used to view hidden processes and occupy CPU resources in real time. It is found that a process that has been occupying a large CPU is interrupted and cannot be terminated.

-----------------------------------------------------

XP interruptions account for a large number of CPU computers. There is a "Hardware interruption" that occupies a large number of CPUs between 10% and 16%, and some people may find about 40% on the Internet.

It is useless to uninstall the driver, unplug the USB, restart the computer, and disable the wireless Nic according to the program on the Internet.

Scanning with 360 is free of viruses, and no exceptions need to be repaired. The 360 hardware master can detect the problem. It is useless to uninstall various plug-ins and recently installed software and restart the computer.

Finally, go to Lenovo's official website and update all drivers online.

Introduction to icesword
It is applicable to Windows 2000, XP, and 2003 operating systems, and has powerful internal functions. It is used to detect and process the behind-the-scenes hacker-Trojan backdoor in the system. You may have used a lot of software with similar functions, such as some process tools and port tools, but now the system-level backdoor functions are getting stronger and stronger, generally, process, port, registry, and file information can be easily hidden. General tools cannot find these "behind-the-scenes ". Icesword uses a large number of novel kernel technologies to prevent these backdoors from hiding.

This ice blade is so good that it will not dynamically update its status. It is not practical at all.

Process Explorer is a free and enhanced Task Manager and the best process manager. It allows users to understand invisible processing programs executed in the background, and can be used to conveniently manage your program processes. Monitors, suspends, restarts, and forcibly terminates any program, including key processes that are not allowed to be terminated at will at the system level, and very concealed and stubborn Trojans. In addition, it also displays the computer information in detail: CPU, memory, I/O usage, which can display the dynamic link library DLL, handle, module, and system process called by a program. View the ownership relationship between processes in the directory tree. You can debug the processes. You can view the process path, company, version, and other details, and display service processes in multiple colors. This is a cool graph. You can replace the task manager that comes with the system. With it, the task manager that comes with the system can be thrown into the garbage bin.
When running process Explorer for the first time, you need to set the font, click "options" and "font", set the font to, and set it to "9.
