I didn t do anything, I couldn t connect to the Internet with 100 CPU

You right-click on the taskbar, open the task manager, open the process, see what's inside that is occupying the CPU, and you end it. You see what it is. Is it a virus? Or what a file.

Probably poisoned, I had a similar problem the other day. As I said upstairs, end the process with a high CPU usage.

Then it's time to use your up-to-date antivirus software.

Ordinary users encounter this situation, there is nothing to say, it must be poisoned, if the Internet is not good, it means that the virus is using your network connection to spread spam packets or the virus itself. What you can do is disconnect from the internet and use the latest antivirus software to kill or redo the system!

If it's serious, you can only choose the latter!!

The biggest possibility is that you are poisoned, just find a cracked version of the antivirus software to kill!

My sister's computer is like this The reason is that the temperature of the CPU is too high, and it will automatically shut down later, you use the software to detect the temperature of the CPU to see if it is, the general CPU is about 50, and the computer will automatically shut down when it reaches 80.

When CPU usage is consistently high, there are several things you can do:

1. Right-click on the taskbar, then click on Task Manager, click Processes, and close the programs that consume high resources.

2. It may be computer poisoning, computer antivirus, it is recommended to disinfect in safe mode.

3. Open less programs that consume more CPU resources.

Probably poisoned. Reinstall the lower system.

You see if there is an error in the process.

Antivirus in the Task Manager to see which process is being consumed.

There is rogue software running in the background, press a c d to bring up the explorer to see which program has the most of it.

But if it's me, it's a direct system restoration, haha, or use ghost to restore the system, Ding, everything is normal! @

It is recommended to install a pure version of the system when you make the system in the future.

I guess it's caused by you running too many programs.

I hope your plane will return to normal soon

Computer card. What to do with CPU100.

With the PC installed.

Procedure. More and more, the CPU usage may be too high or even 100%, causing the program to run unsmoothly.

There are many reasons for high CPU usage, and the common reasons are:

1.System. 2.Infection with malicious programs such as viruses;

The primary antivirus, manual analysis of computer abnormalities, antivirus software.

If you can't find it doesn't mean that it doesn't exist, if you can't analyze it, you can please.

Alone. Take a look at it for you. )

3.Anti-virus software

Firewall. improper use, etc.;

4.Software that opens too many programs that occupy CPU resources;

5.Imperfect is used.

Driver. If the CPU usage is too high, then the computer's.

Computing power. It cannot meet the needs of the program and causes the operation to be unsmooth. Observing the CPU usage can help to find the problem.

Detection of CPU usage.

CPU usage can be done through Windows

XP's own tasks.

Manager. Observe, or pass the limbs of the other.

System monitoring program.

to observe. Use Task Manager to observe CPU usage.

on Windows

xp, press ctrl-shift-esc to open the task manager.

System resources. Usage. Click on the "Processes" tab in it, and you can see the CPU usage of each process.

After that, click on "CPU" on the header line of the information so that all processes are in CPU usage.

Order. arrangement, you can find out which programs are taking up too much CPU resources. (See Managing Processes with Task Manager).

Use the system monitor to observe the CPU usage.

The information in the Task Manager that comes with Windows is not particularly exhaustive, and some specially processed programs (such as viruses, Trojans, etc.) may also be invisible. Using a third-party system monitoring program can help us get a better understanding of the health of our systems.

It is recommended to use the taskinfo program, which can not only give the CPU, but also the CPU

Memory. Occupancy information, but also reporting programs.

Start-up time. Disk.

Information such as the status of reading and writing can be used to determine which programs are causing the trouble.

Some special process descriptions:

sytemidle

process

The system is idle process. This is a normal process and is used to help the CPU save energy and cool down. It is often seen that it seems to "occupy" more than 90% of the CPU resources, when in fact it indicates the idle time of the CPU, and does not affect.

Running speed. In the Windows system, multiple SVCHOST programs will be running at the same time, each providing different services. Under XP, SVChost is generally around 5, and sometimes there may even be as many as one. SVCHOST has complex functions and may be a hiding place for viruses.
