How to solve the high CPU usage of WinXP system?

I believe many people know that the CPU is the computing core and control core of a computer. If the CPU usage is too high, it will affect the running speed of the computer. Recently, users of WinXP have encountered problems with high CPU usage, which causes the computer to crash. The problem of high CPU usage is really a headache. Below, let's take a look at the reasons and solutions for high CPU usage.

Causes and solutions for high CPU usage

1. Large programs

Many times CPU usage is too high due to large programs, such as CPU Large 3D games, there are two reasons, one is that the program is not reasonable, resulting in increased CPU usage (general games are tested, so this situation should be uncommon), the other is computer configuration Too low (this should be the main reason), the solution is very simple, whether you want to play this game, or change the computer with a high.

2, virus and Trojan

As a representative of computer sabotage, which is something you can easily do this. For example, a large number of worms are rapidly replicated inside the system, resulting in a high CPU utilization rate. When you encounter a virus, the first thing you have to think about is the anti-virus software. It is best to check the virus in a safe mode, so that the killing effect is better and more thorough. Anti-virus software should be updated frequently to ensure the killing effect.

3, anti-virus software

Now a lot of anti-virus software have added real-time monitoring (eg mail monitoring, plug-in monitoring, web page monitoring, etc.), although this is well-intentioned, let Our computers are more secure, but they inevitably increase the burden on the system, especially those computers that are not well-configured. They have already "cannot afford" these anti-virus software. The solution is to use the least amount of monitoring or upgrade your computer configuration.

4, the driver

or incompatible driver also imperfect same cause high CPU usage. Many users like to update the driver to the latest when using the computer, and do not look at whether their operating system is compatible with this version of the driver, sometimes the latest is not necessarily the best. Solution, before updating, first check whether the updated version is compatible with your own operating system. When updating the driver, it is best to use Microsoft certified or officially released drivers, and strictly check the model and version.

5, disk fragmentation

We often use the computer when the software will be installed and uninstalled, copy documents and delete operations, this operation will make the hard drive data arranged intermittently It is also very scattered, making the computer slower when searching, and thus taking up a lot of CPU. The solution is to clean up the system garbage frequently and defragment the disk after the cleaning is completed.

6, SVCHOST.EXE

I believe it is no stranger to many of my friends, a lot of time because the process causes CPU 100%, which is a system process, of course, does not rule out Virus forgery, first we need to judge whether it is a virus, there are many ways to judge the method online, Xiaobian no longer repeats, if not we need to see what program is calling it, and then end it. About SVCHOST.EXE has been introduced on the Internet, and the processing methods are also piles of piles. For the sake of comprehensiveness, it is listed here. As for the solution, everyone can Baidu, there should be many methods.

7, IIS server

When IIS server is running over time, will result in increased CPU utilization, CPU after the restart IIS will resume normal value, used to believe People on the IIS server have a deep understanding. For various reasons, Xiaobian is not very clear. Of course, there is no solution. We can set the CPU to be enabled, set the maximum CPU usage, and of course restart the IIS server periodically.

These are the occupancy rate of under WinXP system for several reasons and solutions, in addition to the above points, you can also open the Task Manager using the computer at any time during viewing CPU usage Once the CPU usage is too high, immediately check the usage process and end the process with too high occupancy to ensure that the computer can be used normally, or you can also look at the "9 major reasons and solutions for excessive CPU usage"
