increased CPU usage may be caused by a variety of reasons, ranging from the startup of unnecessary programs and ending with errors in the operating system.To determine the cause of incorrect work computer, open the Task Manager (Ctrl + Alt + Del), look at the overall CPU usage and downloading specific processes.
The most common causes excessive load any one process.Determine what program it belongs to, and if the process is not necessary, close it.Stop-critical processes will not give the operating system, so do not be afraid to spoil anything.At the very least, you'll just have to restart your computer.
If you can not understand the name of what program or service it belongs to, use the program AnVi
r Task Manager or Everest (Aida64).Click in one of these programs, the process list, find the one that loads the processor and see the path to the executable file.After determining what kind of program you are able to decide what to do with it - to leave, change or delete.
increased CPU usage may be caused by a large number of start-up computer programs.Many installed programs seek to register themselves in startup without your permission, so regularly check the Startup list and remove unnecessary programs.To remove, use the Everest: run it, open the "Startup" and remove unwanted programs.
to remove the program from startup, you can use the standard utility msconfig.In Windows XP, open the "Start - Run", type msconfig, and click "OK".In Windows 7, open the "Start" and type msconfig in the search box.In the window that opens, select the tab "Startup" and uncheck unwanted programs, save the changes.
In order to speed up the operating system, turn off unnecessary services, "Start - Control Panel - Administrative Tools - Services".For information on exactly what services you can disable your operating system version, get on the Internet.
one of the worst causes of excessive CPU usage is the operating system error.In this case, the basic Task Manager CPU usage falls on line System.This sometimes happens with unlicensed versions of operating systems and their "advanced" assemblies.After the start of such a system can work normally, but at some point the CPU usage jumps to 100% and is not reduced.The best option in this case - to replace a defective version of the OS it intact.
Sometimes high CPU provides anti-virus program.If this happens temporarily with a peak load of up to 80-90%, then all right.But if the anti-virus constantly and excessively loads the system, replace it with another.
