What s going on with CPU usage at 99

[I hope your plane will return to normal as soon as possible].

Computer card. What to do with CPU100.

As more and more programs are installed in the computer, 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 first antivirus, manual analysis of computer abnormalities, antivirus software can not find out does not mean that there is no existence, if you do not know how to analyze, you can ask someone to help you see. )

3.Improper use of anti-virus software, firewalls, etc.;

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

5.Imperfect drivers were used.

If the CPU usage is too high, then the computing power of the computer cannot meet the needs of the program, resulting in poor operation. Observing the CPU usage can help to find the problem.

Detection of CPU usage.

CPU usage can be done through Windows

XP's built-in task manager can be observed or through other system monitoring programs.

Use Task Manager to observe CPU usage.

on Windows

xp, press ctrl-shift-esc to open the task manager and see the system resource usage. Click on the "Processes" tab in it, and you can see the CPU usage of each process.

After that, click on "CPU" in the header line of the information to arrange all processes in order of CPU usage, and 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 CPU and memory usage information, but also report the program's startup time, disk read/write status and other information, which is more conducive to determining which programs are causing 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's resources, when in fact it indicates the idle time of the CPU, and does not affect the 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.

Take a look at your process, which programs occupy a large number of memory, if it is not a normal process program, terminate it, and then look back to see if your CPU usage has decreased.

You can end up with the one that accounts for the most CPU usage, and give it a try.

Hello, I am glad to serve you and give you the following answers: There are many ways to solve the problem of CPU dropping to 99, and the following is a commonly used method:1

First of all, check whether there is any malware in the system, such as viruses, Trojans, etc., and if there is, delete them in time; 2.Secondly, check whether there are redundant background processes in the system, and if there are, close them in time; 3.Again, check if there are any redundant services in the system, and if there are, turn them off in time; 4.

Finally, check your system for any redundant software, and if so, uninstall them in time. The above is the way to remove the mask to reduce the CPU to 99, I hope it can help everyone.

Hello, it is a pleasure to serve you and give you the following answers: Reasons:1

High system load: When there are too many processes in the system, the CPU gets overused, resulting in CPU downclocking. 2.

Hardware failure: If the hardware fails, it can also cause CPU downclocking. Workaround:

1.Check the system load: Check the number of processes in the system, if the number of processes is too large, you can try to shut down some unnecessary processes to reduce the system load.

2.Check the hardware: Check whether the hardware is faulty, if there is a fault, you can try to replace the hardware to solve the problem.

Steps:1Open Task Manager:

Find "Task Manager" in the start menu, open it, and see how many processes are in your system. 2.Check the hardware:

Check if the hardware is faulty, and if it is, you can try to replace the hardware to fix the problem. Slow tip: When the CPU is downclocked, the first thing to check is whether the system load is too high, if so, you can try to shut down some unnecessary processes to reduce the system load.

If the hardware fails, you can try replacing the hardware to resolve the issue.

In fact, the computer card is nothing more than a few reasons.

1. Query your network.

2. The computer host is too dusty.

The computer host itself is a dust-absorbing thing, if you don't clean it for a long time, the fan won't turn and it will be stuck, and the heat dissipation is not good, you can use a hair dryer to clean up the leakage.

3. Too much computer garbage.

You can use the garbage cleaning function of Tencent PC Manager to clean up the garbage, and we Tencent PC Manager will clean up the garbage and clean it up.

Either your hardware is too poor and the performance is low, or you're poisoned.

The system is running, and your configuration is not high.
