CPU Usage 100 What to do

One would ask: how do you determine if your computer's CPU usage is up to 100%? The problem is simple, right click on the taskbar blank, select "Start Task Manager", switch to the "Performance" tab, you will see the CPU utilization, the following figure:

Since the CPU utilization rate is too high, there are always some reasons, please see the following small series of specific analysis:

First, the anti-virus software caused

Jinshan and rising anti-virus software are added to the Web page, plug-ins and mail random monitoring, which increased the burden of the system. We recommend that you use minimal monitoring services or upgrade your hardware configuration.

Second, virus, Trojan caused

There is a possibility of computer poisoning, a large number of worms in the system to replicate quickly, resulting in high speed increase in CPU usage. Small part of the proposal to use reliable anti-virus software to thoroughly clean up the system memory and local hard drive, and open the system setup software to see if there is no

Abnormal start of the program, often updated anti-virus software and firewalls, strengthen the anti-virus awareness, master the correct anti-virus knowledge.

Third, the driver has not been certified caused

A large number of beta drivers are flooding the web, causing difficult to find fault causes. This requires that you pay special attention to the graphics driver, recommend the use of Microsoft Certified or officially issued by the driver, and strictly check the model, version.

Four, too many startup items caused

Many people like to set up the software to boot, computer startup items more and more, the CPU usage rate will naturally rise. Small set recommend that you close unnecessary Startup items, click Start-run-enter msconfig-to close unwanted startup items.

V. The operation of large programs caused

Some users in the graphics card and other hardware configuration does not meet the needs of the situation, running large programs, such as online games, CPU occupancy rate of course will be high. Small series recommended before running a large program, to see if the computer configuration to meet the minimum configuration to run the program, if the computer is not configured, then the computer hardware upgrade.

Vi. System file Error caused

Sometimes the system files are wrong, which can lead to high CPU usage, or even up to 100%. You can use the system's own zoning inspection and finishing tools for inspection and finishing, start-run-enter cmd, enter "Chkdsk D:/b/x" on the command line, the hard disk fragments are on the line with the system; for bad, you can use hard drive bad track test repair software test to determine the existence, repair.

Summed up six kinds of likely to lead to high CPU usage, we can according to their specific situation to be checked.
