Memory high and CPU needle very erratic

Hello all! My trusty, stable Windows 7 Professional HP Elitebook laptop has encountered an issue that I can't seem to resolve. Typically when I have a browser open, the memory is in the vicinity of 50%, and the CPU needle is relatively steady at about 30%. For the past few days, the memory is over 80% and rises to over 90% over time, and the CPU needle jumps all over the place when a browser is open. When the browser is minimized, the CPU needle teases me with under 10% usage. When a browser window is opened, it will often go to 100%. This happens with both Chrome and Firefox. So something has definitely changed.

 

I immediately assumed virus, but anti-virus and Malwarebytes come up clean. I may have identified the culprit? One svchost.exe file is at 155,000 memory. The rest are all between a few hundred and 8,000 memory. As the image shows, right clicking the file reveals the following highlighted files: wudfsvc, WPDBusEnum, Wlansvc, UxSms, TrkWks, SysMain, PcaSvc, Netman, HomeGroupListener, hidserv, AudioEndpointBuilder.

 

Is this normal? If so, what could be the issue? And if it's not normal, how do I fix this? Many thanks for any ideas!       

Open Google Chrome, and when it starts playing up again, press SHIFT+ESC to open the Chrome Task Manager. Click the column-headings for "Memory footprint" and "CPU" once or twice to display the most memory-hungry and active processes at the top.

 

Also in Chrome, open a "New Incognito window", close the main Chrome instance, and see if the problems occur there too.

 

Let me know what you discover for both suggestions.

 

By the way, the Task Manager screenshot you posted is completely normal.

Get Win 11 it allows you to see what is running in svchost  llllollll

Get Win 11 it allows you to see what is running in svchost  llllollll

So does Windows 7 - its Task Manager is just as capable.

Very interesting, Secret-Squirrel! Thanks for this info. Will try it and report back. 

Chrome is not a very capable memory manager.  For every 10 instances it is around a gig of ram being used.

 

Svchost suggest run Speccy and Publish a Report for here or just for yourself and go through it counting up where your ram is going.

 

(I forgot a lot of Win7, do not understand why it is being used it's so ugly. Each there own).

Hi Secret-Squirrel. The Chrome task manager is replicating what the CPU needle is doing. Soon after opening the Chrome browser, the CPU for the task "Browser" jumps around wildly for a while, ranging from 3.1 to over 80. In a few minutes, it settles down to a range of 3.1 to 15 generally. I don't recall the needle jumping around this wildly before. 

 

Firefox behaves differently. I'll report those findings shortly, after I confirm what I saw initially.  

How many and what extensions are you using ??

 

Please run this and do not skip Basic Repair at the end : https://www.bleepingcomputer.com/download/adwcleaner/

Hi Pkshadow. I was going to say just ABP, but I notice an Acrobat extension also appears for some reason. Will try your recommendation and report back. Since it doesn't seem to be malware, adware is certainly a possibility. Thanks! 

@joezapp:

Just curious:

What version of Chrome are you running on this Win7 computer?

What version of Firefox are you running on this Win7 computer?

Perhaps an outdated browser might be contributing to your current issue?
And many websites now require modern browsers & OS platforms.


FYI Mozilla plans to end support for Fx 115 ESR in September 2024.
https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support

& Chrome 109 was the last version to support Windows 7.
https://support.google.com/chrome/thread/185534985/sunsetting-support-for-windows-7-8-8-1-and-windows-server-2012-and-2012-r2-in-early-2023?hl=en

As such, it would be advisable to plan now for upgrading to a supported version of Windows, purchasing a new computer, or moving to Linux. Continued use of unsupported & insecure browsers on an obsolete & unpatched OS is a recipe for disaster even riskier than it is now.

Thank you. I ran adwcleaner. The quarantined items were largely recognizable, so I restored them. Thanks for letting me know about that tool.

I use a Win 11 for important tasks. Still keeping this Win 7 going to use here and there. It's true that Chrome updates are a thing of the past. Firefox is still updating...for now. 

 

It seems the efforts that I have made have helped, as the system seems all the way back to normal. I'm inclined to think that something unknown was running in the background, and it's now stopped. It could have been legitimate, but certainly also resource intensive, invasive, and unwanted. Sometimes the antivirus software will do that. Chrome used to update unannounced, which was annoying. It does seem that there was no malware or virus, which is always the first thing that comes to mind when the system isn't functioning in the way we're accustomed to.    

 

I did learn quite a few troubleshooting methods from all of you that I did not know before. Many thanks for taking the time to help!

Maybe switch to Firefox ESR it is a few versions back of normal release so is more stable.   Should get a little longer support.

 

Note : Backup bookmarks to HTML and Copy out your Passwords as your Profile will not be compatible (unless changed something am not aware of).

 

 

Seems a little late on regular release re Win7 : https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support

Thank you, Pkshadow. This was valuable info, and it makes me know that it will soon be time to retire this system. It seems, from the way the article reads, that Mozilla would have already updated me to ESR without me needing to do anything. Did you gather the same? If so, it would seem very possible that this update could have been the reason that I encountered something temporarily using a lot of resources on my system.
