Step 5. Take note of the “Image Name” of the process

This will allow you to search the internet for it later, to try to find a solution to this problem and avoid future CPU overload.

Step 6. Click on the rebel program and then click on End Process.

You will be asked to confirm that you want to force the program to close.

  • You do not need to force quit "System Idle Process". If you see that this process is hogging the majority of your CPU, don't worry - it isn't really using system resources. When "System Idle Process" is using a high percentage of the CPU, it really means that your computer has a lot of system resources available.

Search the Internet for the name of the process you forcibly closed. This will help you understand the function of the process, as well as the steps to take to prevent it from using 100% of the CPU. In general, there are several different techniques for combating a program that occupies a large percentage of the CPU.

  • Uninstall it. If the program is not essential, uninstalling it may be the easiest solution to prevent it from slowing down your system.
  • Reinstall or update it. Sometimes a bug in the program can cause it to use all the resources of the CPU. Reinstalling the program or installing an update from its developer may resolve the issue you were having.
  • Remove it from the boot sequence. If the computer startup sequence is slower because of this program, but you need it, you can prevent it from starting when you start your computer.
  • Scan for virus and malware. If your research indicates that the program is a virus, you may need to remove it using anti-virus or anti-malware software. This procedure can be complicated and you may not be able to remove this virus without reinstalling Windows. Click here to learn how to remove a virus.

  • Open Control Panel and click Power Options. If this option does not appear, click on Hardware and audio then on Power Options.
  • Click on the link View additional power plans to expand the list.
  • Click on High performance. All the possibilities of your processor will be unlocked, if this was not already the case.

Your Mac will generate previews of all the files on your desktop and if you have a lot of video files, the procedure can quickly overload your CPU and cause Finder to take up 100% of your CPU. Remove the files from your desktop and put them in a folder, and your computer will slow down only when you open that folder.
