I'm running Windows 7 on an Acer laptop. When I run Task Manager, it shows 100% CPU usage. How can I fix this?

Hello John Aukerman,

 

Download Process Explorer which you can obtain from here

Save it to your desktop then run it (Vista or Win7 - right click and Run as Administrator).  

View, Select Column, check Verified Signer, OK

Options, Verify Image Signatures

 

Click twice on the CPU column header to arrange things by CPU usage, this will put the services with the highest CPU usage at the top of the log. 

 

Wait a minimum of a minute while PE settles down, grab an expanded screenshot and upload it with your next reply.

 

To capture and post a screenshot;

 

Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... Click on the More Reply Options tab then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.

 

 

Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

I followed all instructions. But PE has never settled down. It keeps jumping and changing. 10-15 minutes so far.

Wait until you see the same service that has high usage and then grab the screenshot for us if you can, if you cant, I will provide further steps for you to save the log as txt, I prefer the screenshot as it is quicker to check out and get back to folk.

If you run PE again and svchost.exe is still showing 82% + CPU usage, press the space bar to stop it jumping and then hover over the high svchost.exe and it should tell you what services are involved, if yes, make a note of them and then post the info here for us please.

You need to make a note for yourself as part of the troubleshooting procedure you will be disabling one or more of the services as a process of elimination as the cause

 

Click on Start then Run, type msconfig and press Enter.
Click on the Services tab.
Check the Hide All Microsoft Services box, record what is currently starting then click the Disable All button.
Restart the computer and see how it behaves.
If ok, use msconfig to enable services a couple at a time but leaving what is on your PE list to the last.

I did all this. CPU usage now fluctuates between 76% and 100%. So it's a little better ..... previously it was stuck on 100.

Hi,

 

@Phillpower2: Hope you don't mind with my intromission.

 

@John: Next time you see svchost.exe on Process Explorer with high CPU usage right click on it and select Properties then click on the Threads tab, ignore the warning about Debug and post a screenshot of the window.

 

I suspect the high CPU usage happens because of the Windows Update Client and some bugs introduced by Microsoft on recent updates they did to the WU client.

Sorry the last image doesn't provide the correct information because PE isn't running as Administrator. To start PE Right click on Process Explorer and select Run as Administrator, the repeat the last steps and post a new image.
