The current CPU dual-core is just a fad, not a use (wasn't the previous hyper-threading proof?). ）。
The CPU does not work on multiple tasks at the same time, but one by one. Dual-core is, of course, two at the same time. But that's not the case with your operating system, which only runs the current focus task:
If you are playing a game, the game will stop running after switching to the desktop, except for the necessary processes to maintain the game.
When the landlord tests the CPU, one of the cores runs, and no matter how big the program is, one of the cores will not let the other participate even if it is not enough when it runs at maximum speed. How do I get the other core running? Task more.
But when you run another task, that task takes center stage.

Anonymous users2024-02-03When performing complex tasks, the smaller the usage, the stronger the CPU.

Anonymous users2024-02-02The lower the usage, the better, indicating that your CPU is strong!

Anonymous users2024-01-31First of all, you need to know what kind of CPU you are. What is his processing power.
If it is an ordinary single core, and the external frequency is about 2G, the probability of CPU reaching 50% is relatively high, such as you run image processing software, or some ** is not optimized enough will cause the CPU occupancy to rise.
If your CPU is a high-end single-core or multi-core processor, it will generally not be 50% (more than 2 cores). Even if it is a medium virus, it is difficult to reach such a high occupancy rate. At this time, you can consult your computer seller for technical support, and you can also ask them to diagnose it for you (change the same CPU for Chaozen training without reinstalling the system test), if it is okay, then the CPU is faulty.
If the fault persists, then check if your system has too many services turned on, and if there are programs that are running automatically but not working properly. Whether the memory has compatibility issues with the CPU.

Anonymous users2024-01-30Several possibilities for high CPU occupancy 1. Failure caused by anti-virus software Since the new version of KV, Kingsoft, and Rising have added random monitoring of web pages, plug-ins, and emails, the burden on the system has undoubtedly increased. 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 certified, resulting in 100% CPU resource occupation A large number of beta drivers are flooded on the Internet, resulting in a difficult to find the cause of the failure. 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. Viruses and Trojans cause a large number of worms to replicate rapidly within the system, resulting in a high rate of CPU resource occupation. 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. 4. Control Panel - Management Tools - Services - Rising Realtime Monitor Service Click the right mouse button to change to manual. 5. Start->; Run->; msconfig->；Startup, close unnecessary startup items, restart.
6. Check the svchost process. It is a core process of the Windows XP system. It is not only present in Windows XP, but also in Windows systems that use the NT kernel.
In Windows 2000, the number of processes is generally 2, while in Windows XP the number of processes rises to 4 or more. 7. Check the network connection. The main thing is the network card.
8. Check the network connections When a computer with Windows XP installed is a server, when it receives a connection request on port 445, it will allocate memory and allocate a small amount of CPU resources to serve these connections. When overloaded, CPU usage can be too high because of the inherent trade-off between the number of work items and responsiveness. You'll want to determine the appropriate MaxWorkItems settings to improve system responsiveness.
If you set an incorrect value, the responsiveness of the server may be affected, or a user may monopolize too many system resources.

Anonymous users2024-01-291: The computer configuration is too low, and a lot of programs are installed, so the CPU will often occupy too high, at this time, you can install fewer programs, or upgrade the hardware configuration of the computer;
2: Sometimes the occupation is too high because we run too many programs, close the redundant running programs, and end the process that occupies a lot of CPU;
3: Due to computer virus, anti-virus treatment is required.

Anonymous users2024-01-28There are two reasons for this:
1. There may be viruses lurking in the registry, especially Trojans, which increase the CPU occupancy.
2. Too many unnecessary software programs were launched. Of course, you don't start it yourself, usually they start randomly on their own.
Solution: 1. Antivirus.
Green Simplified Registered Version.
2Run msconfig,Cancel all startup items in the startup project,Only load antivirus and ctfmon(input method),What disease is hibernating,Then you will not reach 100% of the natural CPU when using the computer。
The second trick is the most effective! I've saved several computers this way.
The last trick,The most powerful thing is, of course, to reinstall.,Or if you've made a backup before, just restore the image.。
It can solve the problem that the CPU usage is always 100%.
plump911's is really stupid.,You won't look at that schedule.,There's a call:360SD.,At a glance, you know it's 360 antivirus! (Just kidding, don't take it personally). >>>More
Limited to look at the problem of the computer fan to see if it is normal. It may be because the fan is not rotating well and the CPU temperature is too high. Then look at the software problems, such as dual-core patches, and whether the antivirus software is conflicting, and some antivirus software cannot coexist with each other. >>>More
I'm the opposite of you, I look down on others, and the better people I have, the more I look down on them. I envy you, because it's the Internet, so I dare to say it, people like you are generally very popular, and I don't have popularity, so in summary, people with good popularity have a great chance of getting ahead! People who envy others have good goals and examples to learn from, and I should learn from you.
When we pinch an egg, the force of the hand is evenly distributed to all parts of the egg, not enough to crush it, because the arch is the most stable shape. Arch bridges were built using this principle, and although they looked relatively thin, they were immobile by the heavy traffic that ran over them, such as the Zhaozhou Bridge, where it stood for thousands of years, crossing the other side of the river and gazing down at the rolling river into the distance. People also used this principle to build arches, design cars, airplanes, and helmets. >>>More
First of all, it is recommended to install an antivirus, after all, a computer without antivirus protection is very fragile, even if you don't go to the web casually, don't just accept other people's things, don't mess with things. >>>More
