After the system is powered on, the idle process accounts for 100 CPUs

You should have been poisoned. First, you press Ctrl+Alt+Del at the same time to open the task management, then look at the process to see which process is taking up the most CPU, and stop it (note, except for the last system idle process).After stopping, your computer is basically normal, and then ** the latest version of the antivirus software, the whole antivirus once, it is best to kill the virus in safe mode.

Hope it helps your situation.

Resources occupied by the local connection.

This is normal.

Summary. Hello, I have seen your question and am sorting out the answer, please wait a while The system idle process CPU usage is high.

Hello, I have seen your question and am sorting out the answer, please wait for a while Start Menu - Settings - Devices - Power & Sleep - Other Power Settings - Change Plan Settings - Restore the default settings of this plan. Prompt: "Are you sure you want to restore the default settings for this plan?" Let's click "Yes" and then go to the task manager to see the situation of the CPU.

The problem you are talking about is the problem of the foreground and the background, the system will prioritize the division of system resources to the foreground running program, and what you said switch to B, then B becomes the foreground program, and A becomes the background program, so it will reduce some of the resources used by A to B, so the running speed of A will slow down, and increase the speed of B, which is such a function.

The CPU utilization is too high, which means that the foreground process uses much more system resources than the existing system resources, so it will cause the system to respond slowly, rather than the front-end and back-end problems you are talking about.

And when some programs require much more system resources than they already have, even if you switch to the background, it won't alleviate the lag.

Your assumption simply can't hold up.

Process A occupies all CPU resources, and the system cannot switch to process B at all.

Quite simply, there is no affluent ability to do other tasks.

A computer, which used to be used normally, felt that the working speed was significantly slower after being lent to others for a week.

When such failures occur, they can be considered from the following aspects:

The computer is infected with a virus. After being infected with a virus, the speed of the computer will be slowed down, and the method of checking is antivirus. However, there are many types of viruses, and it is possible that antivirus software may not be able to detect them.

In order to confirm whether the computer has any viruses, you can check it by starting it with a clean and non-toxic floppy disk, checking the directory and running the floppy disk program to see if the display speed and the running speed of the program have improved. If there is an increase in speed, it may indeed be related to a virus in the hard drive.

The CMOS parameters are modified or set improperly, which affects the working speed of the computer. Among them, the following aspects have a greater impact:

ShadowRAM is not set. Generally, the computer is required to set at least the shadow memory of the system BIOS and video BIOS, otherwise it will greatly affect the display speed and working speed of the system.

If the internal cache and external cache are not opened, the computer will work without cache memory, and the working speed of the system will be significantly reduced.

Improper setting of hard disk parameters, especially improper setting of pio parameters of hard disk, will affect the read and write speed of the hard disk. Poor board contact, such as graphics cards, hard disks, memory and other plug-ins, can also affect the speed.

In the case of such faults, you can first use 360 antivirus software to remove viruses, and then check whether the system CMOS parameters are set correctly if the fault still exists after antivirus, open the internal and external caches, and correctly set the PIO parameters and other related parameters of the hard disk, and finally reinstall each board to make it fully contacted.

Re-hit the driver, find the relative app, and delete the app.

Reinstall the system.

Use 360 Security Guard to get rid of some useless system process items and startup items (idle processes don't occupy the system) first

It is not ruled out that the weather is hot and the heat dissipation inside the chassis is not smooth.

The IT in-house ** team is at your service, I hope you are satisfied!!

Now it's summer, if the heat dissipation is not good, the speed will be slow after a period of time

That system idle process doesn't slow down the machine, that means the unused CPU

1.As software versions continue to increase, there are more and more features, so the burden on the CPU will also increase. After a few years, it basically takes up a lot of CPU usage when it is turned on.

2.The more software is installed in the system, the more services the system runs, which will also increase the CPU usage.

3.The system is infected by a virus, or there are background programs that take up a lot of CPU resources.

4.Judging by your symptoms, you can tell that your CPU has been obsolete for several years.

Solution: Reinstall the system, install some necessary software, and see if it is normal. If there is no noticeable improvement, then it is advisable to replace the CPU with a stronger performance. The best and most effective solution is to upgrade your computer.

Occupied all the time after booting? Or will it be occupied after turning it on? Keep occupying that guess you're starting the project too much automatically.

If you have problems with your system or memory settings, try it out for the best results.

Reformatting the system will solve the problem

It may be a temperature problem, see if the heat dissipation path is blocked, the CPU is the core processor of the computer, and a lot of data is processed and cached here, because the work will cause the CPU temperature to rise, so a cooling fan is installed on the CPU, but the cooling fan of the notebook is not on the CPU, but is poured out by a copper rod, and then discharged with a fan, so the temperature of the notebook will be a little higher than that of the desktop.

Because the temperature is too high, it will lead to an increase in the utilization rate of the CPU, the temperature is high, the CPU processing speed will be slow, and a large number of programs to be processed will be blocked in the CPU, in fact, what you are doing is not right, uninstalling antivirus software is the wrong behavior, which will lead to viruses taking advantage of the opportunity, so that it will become toxic if it is not toxic, and you must know the reason for dealing with computer problems.

It's time for you to provide a solution, buy a laptop heat sink, it should be solved, and your computer is a home machine, three people are not good to make normal, don't be too nervous, don't let the computer process too many programs at the same time, and don't work too long.

If you are poisoned, the easiest and most thorough way is to redo the system, if you don't want to redo the system, then you can only do it manually.

In Task Manager, see which process has a high CPU usage, then see where the process is located and delete it in safe mode.

In the task manager, see which process has a high CPU usage, and then see which application this process belongs to? It is better to adopt the corresponding method.

It's an advanced computer and operating system, but if you can't find a process that occupies the CPU, it's a virus, and if you can't change the antivirus software, then you have to do what you don't want to do, reinstall the system.

Windows7 generally eats some memory, but not CPU usage, you try to use the optimization tool to reverse the optimization.

You look at the process, what program is occupying memory, if it's useless and don't let him start, look at the virus.

The most direct and effective way is to rebuild the system, right? It's only 20 minutes, but what about the core 6 cores, how can the powerful CPU use rate be 100? I guess it's a virus.

It's okay to use Kaspersky to kill and kill viruses, but Kingsoft 360's antiviruses are really not powerful. I wiped it, and my AMD FX8150 usage rate is still more than 80.

If it is not a heat dissipation problem or it is poisoned, it is recommended to enter safe mode to kill.

Install an antivirus and scan it. It's possible that hehey has invaded, hehe. If not, check the boot startup item to see which programs are booted up, and turn them off.

RAM 16G, CPU is Core, 6 cores.

Is there any mistake?
