However, it can also occur inexplicably, much to the user’s frustration. We will look at common causes of high CPU usage and slowdowns before attempting to fix them. The problem can be traced to the CPU running too many tasks and processes in many cases.

Cpu Utilization Is High

It is important to check the processor (CPU) if your PC or laptop isn’t performing as well as it should, and high CPU usage is often to blame for poor performance. In case you are experiencing long loading times, crashes, and freezes on your computer, this may be your problem.

As soon as I turned on the computer today, the cursor spun for an eternity before any browser opened, and even when I opened a folder on my computer, it took 30 minutes to reboot.

There are many reasons for high CPU utilization - and in some cases, they are surprising. The slow processing speed may be caused by an anti-virus program you're using, or by a virus that that program needs to stop. Try running a scan with multiple anti-virus tools or manually removing the virus.

If you have a faulty power supply (laptop power cord, desktop power supply), it may automatically start lowering the CPU power to save power. With insufficient power, your processor may only run at a small fraction of its full power, which can lead to 100% CPU usage in Windows 10.
