Sometime, your computer works really slow, the cause can be a process or a program, it’s easy to find what is using your CPU and Physical Memory. There can be a process of a malware, or a program which for any reason can eat your CPU and/or Physical Memory. We can check this through Task Manager.

Check CPU and Memory in Performance Tab in Task Manager

To check what processes are using your Memory, open “Task Manager” by typing in Start Menu “taskmgr” or right click on empty space on task bar and click on “Task Manager”. In Task Manager click tab Performance. As we can see from Graph, it confirms that in our case Memory usage is very high, and CPU is 42% which seems to be High Usage for our Intel i3 1.8 Quad Core CPU.



To find out which process is using so much CPU and Memory we should check Processes Tab.

Check Processes Tab in Task Manager

Click on Processes Tab, click on Memory above the column, it will sort the column from Highest memory usage process to Lowest memory usage process, same we can do on CPU column.


Now analyzing the processes we can easily find out which processes are using too much computer resources. As we see process “example (32bit)” is using 24.9% from CPU and 318MB of Physical Memory. If we are sure that this process is not an important process for PC, but a separate app or even malware, we can kill the process by clicking right click on it and End Task.

Also we see that we have too many Google Chrome processes, which means that there are opened many Google Chrome tabs, and each one is using Physical Memory, we could close some tabs from Google Chrome.

After Killing the Process we don’t need we should check again Memory Tab, and see a good improvement. Task Manager can always help to find what is using too much of your CPU or Physical Memory.

Important Note:

If you think you have some processes which are not from Windows or your Programs, search on Google name of the process.exe, there you’ll find where is it from and what it does.

If you got a malware you should clean your PC from malware and viruses.
