Hi,

 

I have just had some amazing help from Satchfan on the malware forum which has determined that i definitely have no malware on my system. However my problem remains and i have been directed to this forum. 

 

My web browsing has become very very slow when I switch or reload pages. When i open task manager CPU is running at 100% which slowly reduces but still remains over 70%. Desktop windows manager seems to be running at 50% of CPU but the other tasks do not seem to add up to 100% of even 70%. A simlar picture is true when i open resource manager with CPU at 100% but with DWM running at around 25 of CPU. Can anyone help!

 

Many thanks.

What browser are you using when this occurs?

 

What does the CPU usage look like when the browser is closed?

Thanks for the reply

 

I generally use chrome but the same happens with edge and firefox. 

 

with browser and other applications closed when i open task or resource monitor the CPU usage is 100% at first before dropping down to about 70

Open the Task Manager and click/tap on the Startup tab.

 

Please either use the snipping tool or make a screenshot of the Startup apps.

Did you upgrade to Windows 10 from Windows 7?

The machine was originally windows 7 and upgraded quite a while ago but the problem only started very recently.

I honestly don't see enough in the Startup apps to be concerned with.

 

Please create an image of the processes in Task Manager and post them.

You might also try the following...

 

Download and run Sysinternals' Process Explorer.

https://technet.microsoft.com/en-us/sysinternals/bb896653

See which process is using the most CPU and/or memory.

Double click on the process name and select the Threads tab to see which thread is using the most resources.

Also, enable the VirusTotal check in Process Explorer by clicking on Options > VirusTotal.com > Check VirusTotal.com

Use the built-in Windows Snipping Tool to grab screen shots.

Post the images on a site such as Dropbox, Imgur, etc. and paste the links to the images in the thread.

The Process Explorer link doesn't work.

 

I would still like to see that list, including the VirusTotal results.

 

However, Desktop Windows Manager is known for high CPU usage.

 

Check that you have the latest graphics drivers.

 

Adjust the Visual Effects on the system in Advanced System Settings. Try using Adjust for best performance.

I adjusted for performance and still have the problem. There is definitely something wrong. Is there a way of getting to factory reset or something?

Links are fine.

 

Do the following to run the Perfomance Troubleshooter...

 

Type cmd.exe in the search box, and right click on the result, selecting Run as administrator.

Copy/paste the following in the Command line and press Enter...

msdt.exe /id PerformanceDiagnostic
