Ways To Check And Control High CPU Usage

When you are working on your computer and it runs in top speed, it is an indication that your CPU is running fine and fully loaded. Alternatively, it might even slow down drastically and that’s very annoying, especially when you are not even doing anything on it.

The Central Processing Unit (CPU) is the processor that runs everything on your computer. It acts like a human brain controlling everything. Imagine you bombarding too many things to your brain and if your brain is unable to take too many tasks at one time, then it would crash or you would have a nervous breakdown. Similarly, many times if your computer is asked to do too many things at one time, it would gradually slow down and ultimately crash. This problem can be avoided by not using too many applications but sometimes, CPU usage can go out of control. Thankfully, high CPU usage is fixable.

Check for Background Processes – background processes run in your PC even if there is no separate window open for it. Normally, a computer uses many background programs as Windows require some to run. But with downloading of programs over the years, you may pile up some thereby making your PC sluggish. You can check by going to Task Manager. Open the processes tab, where by default it will display usage of each app with the overall usage. The ones using more than 10% of your processors capability are the culprits. Double click and close the programs. Exit Task Manager and restart the computer.
