Windows 10: Computer randomly slowing down

Yesterday, at one point, my Internet connection suddenly became extremely slow, to the point where I was unable to load any pages in Chrome. A few minutes later, the issue resolved itself. I saw in Task Manager that System was using a significant percentage of the CPU during that time, while the memory and disk usage seemed normal. Today, the same thing happened again, but this time I noticed Task Manager kept visually freezing, and hung when I tried to close it. I had never had anything like this happen until yesterday (I've had this computer for 10 months now). Why is this happening?

Specs:
Windows 10 1803 build 17134.765 (64-bit)
Intel(R) Core(TM) i7-7500U CPU @ 2.70 GHz 2.90 GHz

slowness in computer usage.

Hi John,

Thank you for posting your query on Microsoft Community.

I appreciate if you could answer a few questions to narrow down to the issue.

• 
  What is the make and model of the computer?
  
• 
  What makes you think that system is running slow? Is it when you are trying to run application?
  
• 
  Did you install any third party security application?
  

From the screenshot that you have provided, I understood that it’s not the issue with the disk usage. The slowness might be due to the memory usage.

As an initial troubleshooting step, I suggest you to run maintenance task and check if it helps.

• 
  Press Windows key + X from the desktop.
  
• 
  Select Control panel and Select System and Security.
  
• 
  Click on Troubleshoot common computer problems under System and maintenance.
  
• 
  Now Run maintenance task under
  System and security.
  

Hope the information helps. Let us know if you need further assistance. We will be happy to help.

Thank you.
